1. Preface

1. Preface
The Institute for Space–Earth Environmental Research wasestablished on October 1, 2015, by merging the Solar–Terrestrial
Environment Laboratory, the Hydrospheric Atmospheric ResearchCenter, and the Center for Chronological Research at the Nagoya
University campus. The name of the institute represents our mission
to conduct studies to clarify the mechanisms and relationships thatexist between the Earth, the Sun, and cosmic space, treating them asa seamless system, to contribute to solving Earth's current
environmental issues and to expanding human activity out into
space. The new institute is approved to be a new Joint
Usage/Research Center for the period from April 1, 2016, to March
31, 2022. Therefore, we continued our activities both as the Center for
Solar–Terrestrial Environmental Study and as the Center for
Hydrospheric Atmospheric Research from October 1, 2015, to March 31, 2016. The annual report for
the former two centers are published separately, and this report is dedicated to describing the structureof the new institute and its activities for the first fiscal year (October 1, 2015–March 31, 2016).
Previously three different organizations promoted studies in separate research fields even though
they had a common scientific goal. However, we have now succeeded in making our research fields
more closely related to each other, and we have organized our system to make our research fields
further interdisciplinary to create a new research field. We aim to promote interdisciplinary researchusing advanced knowledge and expertise accumulated at our previous laboratory and centers. To start
our activities, we created seven divisions in our Research Department, i.e., Integrated Studies, CosmicRay Research, Heliospheric Research, Ionospheric and Magnetospheric Research, Meteorological andAtmospheric Research, Land–Ocean Ecosystem Research, and Chronological Research, as well as
three centers, i.e., International Collaborative Research, Integrated Data Science, and Orbital andSuborbital Observations. In the research divisions, we emphasize conducting basic science andeducation for undergraduate and graduate students. At the three centers, we primarily conduct
activities to promote joint usage and research. Further, we conduct interdisciplinary studies toeffectively organize the research department and the three centers to explore the continuity of theboundary region and the interaction between the different regions.
To manage the activity of the institute, we have a director and two vice directors, three directors
for the centers, and other necessary people in the administrative department. Further, we have afaculty council to deliberate important matters concerning the organization, human resources,
research plans, and the budget. In addition, to offer various opinions and advice to the institute director,
we have an advisory board that consists of the institute’s professors, professors of associated graduate
schools in our university, and experts from related field outside the university; this promotes ouractivity as a Joint Usage/Research Center.
It is known that the Sun’s activity varies with an approximately 11-year period; however, the 24thsolar epoch that started in the year 2009 has had the lowest activity observed in the last 100 years.
Currently, numerous researchers are concerned about the behavior of the Sun. To understand andforecast such variations in the Sun and its effects on the electromagnetic environments and climate of
the Earth, a program called “Variability of the Sun and Its Terrestrial Impact” (VarSITI), which is
promoted by the Scientific Committee on Solar–Terrestrial Physics (SCOSTEP) has been formed. Oneof the members of our institute was selected as an international leader of this project, and our instituteis expected to play a major role in running this program. It is necessary to conduct research to predict
space weather and to respond to space storms, which could become a serious problem for human beings

advancing out into space, and to understand and to predict extreme weather, which has started tooccur frequently due to global warming. In terms of considering long-term fluctuations in extreme
weather and global climate, the energy balance of the Earth’s surface is an important issue. In thiscase, greenhouse gases, such as carbon dioxide, aerosols, and clouds formed using aerosols as a nucleus,
are important elements. Further, the formation of clouds causes more rain to fall, and the circulationof water associated with precipitation has a significant influence on the land vegetation and marine
ecosystems, and these ecosystems control the climate and weather in turn. There are certain locations
where disasters related to water, such as heavy rain, typhoons, and floods, occur frequently, and there
is a hypothesis that the circulation of water is changing due to global climate change; therefore, theimportance of these studies is increasing. We conduct interdisciplinary studies of phenomena that
occur in the atmosphere, ocean, and on land using in-situ observations, satellite observations, andnumerical models, and we plan to contribute to society by applying the outcomes of our research topreventing disasters, protecting the environment, and understanding the causes of extreme weather.
To promote such interdisciplinary studies, we created the following four projects, i.e., solar–terrestrial
climate research, aerosol and cloud formation, the interaction of neutral and plasma atmosphere, andspace–Earth environmental prediction.
As for joint usage/research activities, we offer the following programs: ISEE International Joint
Research Program, ISEE/CICR International Workshop, Joint Research Program (International,
General, Student Encouragement, Symposium, Computing Infrastructure, Database Management,
and Accelerator Mass Spectrometry Analysis), and Carbon 14 Analysis Service.
The faculty members at our institute belong to one of the following graduate schools, the graduate
school of science, the graduate school of engineering, and the graduate school of environmental studies,and are involved in their educational activities.
We have participated in the 21st Century COE program, the Global COE program, and the Leading
Graduate School program and have been involved in educational activities related to these programs.
Therefore, we are further developing educational content, using our infrastructure and humanresources, to foster young students in this interdisciplinary environment in which the subjects ofscience, engineering, and environmental studies are truly intermixed with each other. At the sametime, we foster people who can play an active role in various fields in society, such as in companies andin governments, to solve the various issues that humans are encountering. In addition, we aim tocontribute to the internationalization of our community by dispatching students overseas as well as
accepting students from foreign countries. As mentioned above, we plan to deploy the international
joint research program to study the space–Sun–Earth system comprehensively and to settle issues inEarth’s environment and in our space activities, such as Earth’s climate variation, which depends onsolar activity, predictions of the space–Earth environment, and extreme weather.
We will try to make our efforts at the center of space–Earth environmental research open to theworld to contribute to academic and social developments. I sincerely ask everyone for theirunderstanding and cooperation for our institute and our activities.
As mentioned at the beginning, this report describes the structure of the new institute and its
activities for the period from October 1, 2015, when our institute was formed, to March 31, 2016. We
hope this report helps you understand our activities and the current status of our institute.

5. Joint Research Programs
One of the major functions of the ISEE is to promote and conduct collaborative research on Space–
Earth Environmental Science together with researchers from universities and institutes outside the
ISEE. On January 14, 2016, the ISEE was certified as a core research institution of Space–EarthEnvironmental Science, which is a “Joint Usage / Research Center” as defined by MEXT of Japan.
We prepared application forms for joint research programs focusing on the following two researchissues. One is the “Study of coupling processes in the solar–terrestrial system using ground-based
observation network,” and the other is the “Establishment of an international collaborative research
hub to solve research issues in the global (terrestrial) environment and space applications based oncomprehensive studies of the space–Sun–Earth system.” The former focuses on coupling processes
in the solar–terrestrial system and the interactions of neutral and plasma components in the Earth's
atmosphere by establishing an international ground-based observation network ranging from low tohigh latitude regions, especially in Asia and Africa. The latter aims to establish an international
collaborative research hub for comprehensive studies of the space–Sun–Earth system, space
applications, space weather forecasting, and environmental problems, such as global warming. The
following ten research programs were prepared for the application during the 2016 Japanese fiscal
year.
01) Joint Research Program (International)
02) ISEE International Joint Research Program (*)03) ISEE/CICR International Workshop
04) Joint Research Program (General)05) Joint Research Program (Student Encouragement)
06) Joint Research Program (Symposium)07) Joint Research Program (Computing Infrastructure)08) Joint Research Program (Database Management)09) Joint Research Program (Accelerator Mass Spectrometry Analysis)10) Carbon 14 Analysis Service(*) Applicable only to foreign researchers

These collaborative research programs will be executed using the instruments, software /databases, and facilities of the ISEE. Joint research programs from 01) to 03), described above, will
be managed by the Center for International Collaborative Research (CICR). Those of 07) and 08)
will be managed by the Center for Integrated Data Science (CIDAS), and 09) - 10) will be managed
by the Division for Chronological Research.

Introduction to Division for Integrated Studies
The solar-terrestrial environment is a complex system that consists of nonlinear,
non-equilibrium, and multi-scale interacting processes. The research activities in the Division for
Integrated Studies aim to understand the mechanisms, as well as predict the dynamics, of various
phenomena in the solar-terrestrial environment via data analyses and modeling studies. Some of
their major results are introduced below.
1. Microwave Observations of White-Light FlaresWhite-light (WL) flares are solar flares that are enhanced in the WL continuum. To investigate thekey factors generating a WL flare, we analyzed six WL and four non-WL (NWL) flares. The
microwave spectrum has a peak at the so-called turnover frequency. WL flares show systematicallyhigher turnover frequencies, which might correspond to stronger magnetic fields. This is consistent
with the fact that WL flares tend to be compact. NWL flares tend to show spectral hardening in time;
this indicates that the magnetic mirror effectively works due to the weak magnetic field in the loop.
2. The Trigger Mechanism of Solar Flares
Solar flares are explosive phenomena, in which free energy stored in the solar corona is disruptively
liberated. However, their triggering mechanism is still not sufficiently understood, and therefore ourcapacity to predict the occurrence of solar eruptions and to forecast space weather is substantiallyhindered. We recently revealed, using numerical simulations and analyses of solar magnetic field data
observed by the Hinode and SDO satellites, that internal reconnections between sheared magnetic
fields and small-scale magnetic fields of two different structures can trigger solar flares. We further
studied the detailed trigger process based on a statistical analysis of the magnetic field data anddata-driven simulations, in which the photospheric boundary condition was given by the data. As aconsequence, we successfully reconstructed the three-dimensional structure of the magnetic field
during the flaring process and found an MHD instability that may trigger the initial phase of the flares.
3. Solar Cycle Variation of Coronal Heating Characteristics Above the Polar Coronal HoleWe studied the coronal heating process above the polar coronal hole using Hinode/EIS data. The
corona above the polar coronal hole is very dark at EUV wavelengths. The stray light/scattered
light from the solar limb/disc may affect this result. Therefore, we tried to model the straylight/scattered light effect using a Moon eclipse event or a Venus transit on the solar disc event. We
statistically studied the solar cycle variation of the coronal heating characteristics above the polar
coronal hole. We found that the characteristics of the coronal heating process seem to change fromfast solar wind (solar minimum) to slow solar wind (solar maximum).

4. The Energy Spectra of the Pulsating Aurora and the Frequency Spectra of the Chorus Waves
We investigated the origin of the fine structure of the energy spectrum of precipitating electrons
in the pulsating aurora (PsA) observed by the low-altitude Reimei satellite. The main modulation of
the electron precipitation, of a few seconds, and the internal modulations, of a few hertz, which areembedded inside the main modulations, was identified above ~3 keV. Moreover, stable
precipitations at ~1 keV were found for the PsA. A “precipitation gap” was discovered between twoenergy bands. We identified the origin of the fine structure of the energy spectrum for the
precipitating electrons using a computer simulation. The lower band chorus (LBC) bursts cause themain modulation of the energetic electrons, and their generation and collapse determines the on-off
switching of the PsA. A train of rising tone elements embedded in the LBC bursts drives theinternal modulations. A close set of upper band chorus (UBC) waves causes the stable precipitationsat ~1 keV. A wave power gap near the half gyrofrequency at the equatorial plane in themagnetosphere between the LBC and UBC reduces the loss rate of the electrons in the intermediate
energy range, forming a gap of precipitating electrons in the ionosphere.
5. Stepwise Tailward Retreat of Magnetic Reconnection: THEMIS Observations of an Auroral Substorm
A multiple-onset substorm that occurred on February 27, 2009, was investigated Five successive
auroral brightenings were identified at approximately 10-min intervals. The first brightening was afaint precursor. The second one had a wide longitude and therefore represents the Akasofu
substorm onset. The other brightenings expanded poleward and therefore were interpreted to beauroral breakups. They occurred stepwise; that is, later breakups were initiated at higher latitudes.
Their corresponding reconnection signatures were studied using THEMIS satellite observations
from between 8 Re and 24 Re down the magnetotail. The Akasofu substorm onset was notaccompanied by a clear reconnection signature. Conversely, the three subsequent auroral breakups
occurred concurrently with three successive fast flows at 24 Re; accordingly, these breakups havebeen interpreted as being associated with impulsive reconnection episodes. These three fast flows
consisted of one tailward and two subsequent earthward flows. The flow reversal at the second
breakup indicated that a tailward retreat of the near-Earth reconnection site occurred during thesubstorm expansion phase. This tailward retreat is likely to have occurred in a stepwise manner.
We interpreted the stepwise characteristics of the tailward retreat and poleward expansion topotentially be associated with the stepwise magnetic flux pile-up.
6. Ion Gyro-Viscosity in the Kelvin-Helmholtz Instability
The Finite-Larmor-radius (FLR; gyro-viscous) term was evaluated using a full kinetic Vlasov
simulation result for the Kelvin-Helmholtz instability (KHI). The velocity field and the pressure
tensor were calculated from high-resolution data of the velocity distribution functions obtained by
the Vlasov simulation, which was used to approximate the FLR term according to Roberts andTaylor (PRL, 1962). A direct comparison between the pressure tensor and the FLR term shows
agreement. In addition, the off-diagonal pressure gradient enhances the linear growth of the KHI
when the inner product between the vorticity of the primary velocity shear layer and the magnetic
field is negative, which is consistent with previous FLRMHD simulation results. This suggests that
it is not sufficient when reproducing the kinetic simulation results using fluid simulations to only
include the FLR term (or the pressure tensor) in the equation of fluid motion.

Introduction to Division for Cosmic-Ray Research
Cosmic rays, which are mostly protons with small amounts of charged particles such as electrons or
nuclei and neutral particles such as gamma rays or neutrinos, are produced in space and propagate
through interstellar and interplanetary magnetic fields before reaching the Earth. The Division for
Cosmic-Ray Research performs cosmic gamma-ray observations using the Fermi Gamma-ray Space
Telescope (Fermi satellite) and the Cherenkov Telescope Array (CTA) and high-altitude solar neutron
observations to reveal the cosmic-ray acceleration mechanisms as common space plasma phenomena.
Cosmic rays also provide hints for ultra-high energy phenomena and unknown particles that cannot be
explored in a laboratory. We conduct LHCf and RHICf experiments to study hadronic interactions ofultra-high energy cosmic rays using accelerators such as LHC or RHIC. This division also conducts
neutrino physics research with the Super-Kamiokande experiment and participates in the XMASS liquid
xenon experiment at the Kamioka Observatory in Japan to search for dark matter.
Cosmic rays deeply penetrate the atmosphere, producing ionization and cosmogenic nuclides. Our
division studies past solar activities and sudden changes in cosmic-ray flux that are recorded in the
carbon-14 fractions of ancient tree rings and other cosmogenic nuclides from Antarctic ice cores.
In addition, this division conducts the MOA experiment with a dedicated 1.8-m wide-field opticaltelescope at Mt. John University Observatory in Tekapo, New Zealand. It conducts surveys ofgravitational microlensing due to massive astrophysical compact halo objects (MACHOs) or exoplanetsand optical follow-up observations of gamma-ray bursts and gravitational wave events.
Main Achievements in FY2015
1. Cosmic gamma-ray observations
We conducted morphological studies of supernova remnant IC 443 as a verified galactic
cosmic-ray source using the Fermi satellite. We found that acceleration characteristics of cosmic
rays are rather uniform in IC 443. We also searched for gamma-ray signals from annihilation of
weakly interacting massive particles (WIMPs) in the Galactic Center and nearby dwarf galaxies
using the Fermi satellite, excluding WIMPs with a mass region below 100 GeV/c2. In parallel, wedeveloped custom integrated circuits and silicon photon sensors for the Gamma-ray Cherenkov
Telescope of the CTA. We fabricated a prototype in December 2015 and successfully observed
cosmic-ray air showers for the first time in CTA. Furthermore, we played a central role indeveloping a new-generation gamma-ray instrument, the Soft Gamma-ray Detector, which launched

19 Institute for Space–Earth Environmental Research7-1. Research Divisions

onboard Hitomi, a JAXA X-ray Satellite, on February 17, 2016. Commissioning of the instrument wascompleted on March 25, but the mission was terminated owing to an accident on March 26, 2016.

2. Solar neutron observations using SciCRT
We installed a new detector SciCRT at Sierra Negra, Mexico, (19°N, 97°W, 4600 m) in April 2013
and started data taking using 3/8 volume of a full detector for the muon telescope and the solar
neutron telescope. We developed a new, fast data acquisition system using a network processor
called SiTCP, developed by KEK, and installed it for the data taking of 1/8 of the full detector.
3. Cosmic neutrinos and direct dark matter search
We performed a design study for the Hyper-Kamiokande detector that aims to enlarge thefiducial volume of Super-Kamiokande by a factor of 20. We conducted research and development
activities for a new photomultiplier tube (PMT) dedicated to Hyper-Kamiokande and studied
various performance aspects of the PMT, such as incidence position dependence. We also conducted
WIMP direct searches using the XMASS liquid xenon experiment and published emission timemeasurements of xenon scintillation light irradiated by low-energy gamma rays. Moreover, wedeveloped a single-phase liquid xenon TPC prototype with thick glass GEM electrodes.
4. Studies of cosmic-ray interactions using accelerators
A highlight in 2015 was collecting data from proton-proton collisions at 13 TeV in the LHC. We
gathered physics data for 27 hours, taken over the course of three days of a special physics run for
LHCf in June, after which the detectors were removed from the LHC. We also continued analyses ofdata taken before 2015 and published cross-sections of neutron production in 7-TeV collisions andneutral pion production in various collisions. A proposal for a new experiment to take data during
510 GeV proton-proton collisions planned for 2017 at the RHIC at Brookhaven National Laboratory
in U.S.A has been approved and preparation is now in progress.
5. Past cosmic-ray variability probed by cosmogenic nuclides
We continued C-14 and Be-10 measurements for the AD775 and AD994 cosmic-ray
rapid-increase events discovered in 2012-13 and confirmed that the AD775 event was found in
Be-10 data from the Dome Fuji Antarctica ice core. We also measured old tree rings in the U.S. andfound a possible rapid-increase similar to the AD775 one.
6. Laboratory experiment for cloud formation by cosmic rays
In 2015, we continually studied cloud formation in a reaction chamber using high-energy proton,
nitrogen ion, and xenon ion beams at HIMAC as radiation sources. We found that cloud density
depended on ion density and formation rate seems unrelated to beam species.
7. Search for exoplanets and optical counterparts for gravitational waves by a wide-field opticaltelescope
In 2015, we detected 577 microlensing events and issued real-time alerts to follow-up groups. We
discovered eight candidates for new exoplanets. Among the past events, we found six new
exoplanets, bringing the total number of exoplanets discovered by microlensing to 46. We also
observed the occultation of a star by Pluto in June. In addition, we executed follow-up observations
for the first gravitational wave detection by the LIGO group on September 14, 2015 using a 61-cm
B&C telescope. We found no suitable candidates for optical counterparts.

Introduction to Division for Heliospheric Research
We have conducted remote-sensing observations of the solar wind since the 1980s using themulti-station Interplanetary Scintillation (IPS) system. Tomographic analyses of IPS observations
enable accurate determination of the global distribution of the solar wind speed and density
fluctuations. IPS observations provide valuable information particularly for high-latitude solar
wind, where in situ observations are currently unavailable. We investigate the global structure of
the solar wind, the acceleration mechanism of the solar wind, the propagation ofinterplanetary-coronal mass ejections (CMEs), and their solar cycle dependences using IPS.
Main Achievements in FY2015
1. North–South Asymmetry in the Solar Wind Structure at the Solar Cycle 24 Maximum
The Solar Cycle 24 (SC24), whose activity is the lowest observed in the past 100 years, passed its
maximum phase and is currently entering its declining phase. The structural evolution of the solar
wind during the SC24 maximum to declining phase, that is, the appearance of a fast solar wind at
the poles, was clearly discernible from our IPS observations. Polar fast winds observed by IPS
showed marked differences in their distribution between the north and south. Such an asymmetric
distribution of the polar fast wind has been observed in the maximum phases of past cycles.
However, the asymmetry of this cycle lasted longer than that of past cycles. The north–south
asymmetry of the polar fast winds is likely due to the effect of the Sun’s magnetic field. We
compared our IPS data with magnetograph observations at the Wilcox Solar Observatory. As theresult, we found a significant correlation between the observed asymmetry and the ratios of thequadrupole to dipole moments of the Sun’s magnetic field.
2. International Collaborations for Space Weather Forecasts
We collaborated with Dr. B. V. Jackson and his colleagues at the University of California, San Diego on
3D reconstructions of the time-varying heliosphere from tomographic analyses of the IPS observations.
The time-dependent tomography (TDT) program was developed via this collaboration. This program is
now freely available to researchers on the web server of the NASA Community Coordinated ModelingCenter (CCMC) and is also running at the Korean Space Weather Center (KSWC) in real-time to predict
the solar wind at the Earth. The TDT enables the determination of the solar wind speed and density at
the Earth using our IPS observations. To make reliable predictions of space weather, information about
the interplanetary magnetic field (IMF) is necessary. A computer system to predict the IMF wasestablished at KSWC by combining the TDT analysis and the ENLIL solar wind model (developed by Dr.
D. Odstrcil, GMU/NASA). The IMF Bz (north-south) component is particularly important, because it
21 Institute for Space–Earth Environmental Research7-1. Research Divisions

controls the influence of solar wind disturbances on the Earth’s magnetosphere, and reliable predictions of
the IMF Bz are required. We collaborated with Dr. Jackson’s group to improve the IMF Bz prediction by
combining a potential field model of the Sun’s magnetic field and the TDT analysis of the IPS data. The
results obtained so far show that a significant correlation exists between the calculated fields of thepotential field model and the IMF Bz data observed near the Earth.
3. Study on the Propagation Dynamics of CMEs
Precise predictions of CME arrivals at the Earth are important from the viewpoint of space
weather forecasts. CMEs are known to accelerate or decelerate during propagation in the solar
wind. However, their physical processes are not yet fully understood, and this results in large errors
in the prediction of CME arrival times. We collaborated with Dr. S. Yashiro (Catholic University) on
the acceleration/deceleration of CMEs using our IPS data and SOHO/LASCO observations. As aresult, we found an excellent correlation between CME acceleration rates and its speed relative tothe ambient solar wind. This suggests that the acceleration/deceleration of CMEs is controlled byinteractions with the ambient solar wind, and this is thought to be an important finding that willlead to improvements in space weather forecasts.
4. Very Low Density and Very Low Speed Solar Wind
The density of the solar wind according to in-situ measurements in SC24 decreased more than
30% compared to SC23. Recent IPS observations also indicate that very low speed solar wind has
decreased density. We analyzed solar wind with very low density and very low speed (LDSW) toreveal the origin of this peculiar solar wind and its solar cycle dependence using IPS data from 1997
to 2014. We found that the LDSW originating from mid-latitudes (30–50°) increased remarkably in
SC24. In addition, we determined the coronal magnetic properties via PFSS analysis and foundthat the magnetic field strength in the photospheric origin of the LDSW decreased in SC24;
however, the magnetic expansion factor did not change significantly. We concluded that LDSW
originating from open magnetic field regions in quiet regions increased remarkably and that the
supply of mass flux from these regions into the corona decreased in SC24.
5. Determination of solar wind density and temperature using the IPS-MHD tomography method
The solar wind is a consequence of coronal heating and solar wind acceleration processes that have notbeen completely solved. The solar wind is the background for the propagation of interplanetary
disturbances. To address the unknown coronal dynamics and enhance our capabilities in the space
weather paradigm, it is important to determine and characterize the solar wind plasma quantities on a
global scale. In this context, IPS solar wind speed data provide a unique and powerful observation-based
approach. We recently developed a new approach to find a three-dimensional MHD solution of the solar
wind solution that simultaneously satisfies three theoretical and observational constraints, the MHD
equations, the IPS-LoS observation of the solar wind speed, and the in-situ measurements (ULYSSES
and/or the near-Earth OMNI dataset). The preexisting IPS-MHD tomography can find solutions
satisfying the first two constraints. By embedding an optimization algorithm to satisfy the third
requirement in the tomography method, we can now derive MHD solutions of the solar wind that are
more realistic. An advantage of this new optimization method is that we can determine solar windsolutions from the early 1970s until now and assess long-term variations in the solar wind characteristics.
The dependency of solar wind plasma on the solar cycle and/or coronal magnetic field found in the results
could be key to enhancing our understanding of solar coronal heating and acceleration processes.

Introduction to Division for Ionospheric and Magnetospheric Research
The Division for Ionospheric and Magnetospheric Research investigates the physical processes oftransfers of matter and energy from the magnetosphere to the ionosphere and thermosphere. The
plasma and energy carried by the solar wind to the Earth and other planets exert physical effects on
the magnetosphere and ionosphere; in other words, the region known as geospace. We study theseeffects and associated phenomena with international cooperation primarily through various
observational approaches using ground-based instruments, for example, EISCAT radars, HF/VHF
radars, GNSS receivers, high-sensitivity passive/active optical instruments, magnetometers, andinstruments onboard satellites/spacecraft, which are developed in our division. We also lead future
space exploration missions based on our expertise. Remote sensing data are combined with in situ
measurements from rockets and satellites/spacecraft for studying dynamic phenomena in geospace.
These data are then used to study the interactions between space plasma and the Earth's
atmosphere, as well as couplings between the high- and mid-latitude regions.
Main Achievements in FY2015
1. Lower thermospheric wind variations in auroral patches
Auroral patches, which tend to appear during the second half of the substorm recovery phase,are characterized by an eastward drift along the ionospheric convection path and a relatively clear
edge of each patch. Many measurements with a Fabry-Perot interferometer showed that lower
thermospheric vertical winds fluctuated with amplitudes of greater than tens of m/s only in thedarker area and/or at the edges of patches. We investigated their presence by analyses ofmeasurements by EISCAT radars and the results of simulations.

3. GNSS observations of ionospheric irregularities in equatorial regions
In order to observe ionospheric irregularities in equatorial regions, wehave been operating GNSS receivers at Abuja, Nigeria and Chiang Mai,
Thailand since March 2016. These receivers track GNSS signals from
GPS, GLONASS, and Galileo satellites at triple frequencies so that total
electron content (TEC) and scintillation data can be obtained
simultaneously at multiple points. At both Abuja and Chiang Mai, optical
instruments belonging to Optical Mesosphere Thermosphere Imagers(OMTIs) are in operation. Coordinated observations with the GNSS
receivers and the optical instruments could enable us to reveal thestructures of the ionospheric irregularities and disturbances.

Experimental development and facility improvement of the Atmospheric Neutral Analyzer(ANA) for realizing in situ observations of the terrestrial and planetary upper atmospheres
In order to understand the atmospheric circulations, heating, and dissipation, observations ofneutral particles in the terrestrial and planetary upper atmospheres have been carried out overmany years. For further detailed investigations of these dynamics in the neutral upper
atmospheres, in situ observations utilizing spacecraft are required. We are newly developing a
Bennett-type radio-frequency mass spectrometer, which is called the Atmospheric Neutral Analyzer(ANA). The ANA is capable of observing 2D velocity distributions, from which the density, windvelocity, and temperature are derived, for each component of neutral species. We use asuprathermal ion beamline for the calibration of the ANA and are now improving the capability ofthe beamline in order to obtain more detailed specification data of the ANA.

Calibration of the space plasma particle analyzers for the ERG
geospace exploration mission
We conducted laboratory calibrations of the space plasma particle

analyzers for the ERG geospace exploration mission, which will belaunched in 2016 in order to carry out in situ observations of the plasma
dynamics occurring in the terrestrial radiation belts. We have completed
the calibration of the medium-energy ion analyzer, which is one of the six
particle analyzers on the ERG mission, using a high-energy beamline in
our institute. The results indicated good agreement with the numericaldesign performance and previous experimental data, and we also obtained
more detailed calibration data for evaluating the instrument specification.

Introduction to Division for Ionospheric and Magnetospheric Research
The ongoing global warming, due to an increase in carbon dioxide and other greenhouse gases,
will not only result in gradual climate change but may also lead to an intensification of weather
extremes and ecological catastrophes. To better confront global environmental problems, one of ourmost urgent tasks is to closely monitor the atmosphere using various means of observations and tobetter understand the atmosphere using theoretical insights and numerical modeling. To addressthese problems, the Division for Meteorological and Atmospheric Research is dedicated to a numberof research projects to explore the atmosphere from a range of different angles.
Main Achievements in FY2015
1. Balloon-borne measurements of CO2 and O3 vertical profiles over Syowa Station, Antarctica
We conducted balloon-borne measurements of CO2 and ozone to obtain detailed information on
the source and sink of CO2, the transport of air masses, and the chemical reactions of ozone in
Antarctica. As a result, the influence of the uptake of CO2 by the ocean and the depletion of O3 byphotochemical reactions with halogens emitted from the ocean was detected.
2. Continuous in-situ observations of CH4 using an open path sensor at a paddy field in India
We have conducted in-situ observations of CH4 at north of Delhi, India, since the end of 2014 using
a low-cost CH4 measurement system based on laser absorption spectroscopy. Large variations in theCH4 concentrations between day and night often appear, especially in winter, likely due to theformation of a stable boundary layer during the night. In addition, concentrations of CH4 increased in
the monsoon season due to large CH4 emissions from the paddy field during rice cultivation.
3. Observations of the light absorption properties of black carbon particles at the Noto Peninsula
Coating black carbon (BC) with inorganic salts and organic compounds can enhance themagnitude of light absorption by BC. To examine the enhancement of light absorption of aged BC
particles, we conducted observations of particles at an Asian outflow site at the Noto Peninsula inJapan. A large enhancement in the light absorption of coated BC of up to approximately 50% was
observed when the air mass was transported long-range from urban areas in China.

4. Assessment of a Satellite-based Atmospheric Budget Analysis Method with Ground Data
For global climate research, it is critical to better understand tropical convective systems. A
developed satellite-based method to analyze moisture and the thermal budget was examined incomparison with sounding array observations from CINDY2011. Overall, the satellite analysis wasfound to quantitatively reproduce the statistical behaviors of large-scale mean vertical motion, moisture
convergence, and moist static energy (MSE) convergence as observed from the sounding arrays.
5. Analysis of Arctic Mixed-Phase Clouds Using a Cloud Radar
Mixed-phase clouds are clouds in which ice particles and liquid droplets coexist below the freezing point. In
the Arctic boundary layer, mixed-phase clouds are frequently observed and maintained up to several days. The
maintenance mechanisms and climatological roles of Arctic mixed-phase clouds are currently being examined.
In this study, an estimation method for ice mass fluxes at the mixed-phase cloud bases was developed using a
Ka-band vertical pointing cloud radar. Theoretical considerations showed that the riming process must be
taken into account for clouds with high liquid water paths, even for clouds developing in high latitudes. This
result provides both a constraint for studying the maintenance processes of clouds and an observational
estimation for comparisons with numerical simulations.
6. End of mission experiments of the Tropical Rainfall Measuring Mission (TRMM) satellite
The TRMM satellite re-entered the Earth's atmosphere on June 16, 2015. During its descent,special experiments using the Precipitation Radar were implemented to obtain fundamental data
for future spaceborne precipitation radar designs. Early analysis results indicate that a wide swath
observation can be achieved with the current radar design. The incident angle dependency of thesurface echo from a single target was confirmed via a 90-degree yaw experiment.
7. Monitoring of stratospheric ozone, UV, and aerosols in the Patagonia region, South America
A joint research project called the “Development of the Atmospheric Environmental Risk

with Argentina and Chile. In 2015, we made several campaign observations during the period from
October to December, coordinating with the Differential Absorption Lidar (DIAL), ozonesondes, and themillimeter-wave radiometer. Comparisons show a good agreement between these instruments within adifference of 10% at altitudes ranging from 20 km to 35 km. We also detected significant variations in
the vertical profiles of ozone during the period when the site was located within the ozone hole.
8. Measurements of composition changes in the polar stratospheric and mesospheric atmosphere
The polar middle-atmosphere is a region where energetic particle precipitation (EPP) events due
to solar activity frequently occur due to the configuration of the magnetic field. The ISEE and the
National Institute of Polar Research (NIPR) started ground-based observations at Syowa Station in
Antarctica in March 2011 using a millimeter-wave spectroscopic radiometer, and we have carriedout continuous monitoring of millimeter-wave nitric oxide (NO) and ozone spectra since January
2012. An analysis of the monitoring data obtained over four years clearly detects seasonalvariations peaking near polar winter, except in 2014. In addition, several events of short-term
sporadic enhancement lasting for several days were observed in the fall of 2015.

Introduction to Division for Land–Ocean Ecosystem Research
The Land–Ocean Ecosystem Research Division investigates regional and global energy, waterand material cycles, and physical/biogeochemical processes in the land–ocean ecosystem primarily
via in situ observations, data analysis, and numerical modeling.
On land, synthetic research is performed using in-situ observations, sophisticated coupled land–
atmosphere models, atmospheric reanalysis data, and remote sensing to understand therelationships between climate change and water/material cycles over land from the tropics to thenorth polar region. We observe precipitation, evapotranspiration, soil moisture, carbon dioxide, andthe methane budget at multiple observation sites. We intensively investigate how anthropogenic
forcing, such as land-use and land-cover change; surface conditions, such as sea-ice change and sea
surface temperature; and the responses of vegetation interact with local and global climate systems
through the atmospheric water cycle.
Ocean research is performed using satellite remote sensing, numerical simulations, and in-situ
observations. We perform synthetic studies of physical and biogeochemical processes in the ocean
and their interactions with the atmosphere and climate. In particular, we investigate the manner inwhich oceanic heat content, circulation, and surface waves interact with atmospheric environments
and how they are linked to climate and meteorological phenomena such as tropical cyclones. We
also investigate how the variations in ocean circulation, mixing processes, and air–sea fluxes
influence marine ecosystems where phytoplankton is a primary producer. Moreover, we areinterested in the possible impact of the marine ecosystem on physical processes and climate in theocean and atmosphere.
1. Interdecadal changes in the interannual variability of precipitation and atmosphericcirculation over northern Eurasia
We found interdecadal modulations in the relationships between the interannual variability insummer (June, July, and August) precipitation and atmospheric circulation patterns in three major
Siberian river basins (Lena, Yenisei, and Ob) over northern Eurasia. The interannual variations insummer precipitation over the Ob and Lena River Basins were negatively correlated from themid-1970s to the mid-1990s. By contrast, a significant positive correlation was apparent between
the Yenisei and Lena River Basins after the mid-1990s. We also found that there has been asignificant increasing trend in the geopotential height in the low-level troposphere since the27 Institute for Space–Earth Environmental Research7-1. Research Divisions

2. Reducing Errors in Satellite Chlorophyll-a in the Ise/Mikawa Bay and Absorption Aerosols
Phytoplankton is an ocean primary producer
and the base for fish production. However,phytoplankton abundance often increases toomuch due to human nutrient input in coastal
areas and forms red tides, which sometimes
harm aquaculture and form anoxic conditions in
the water. Ocean color remote sensing is a useful
tool to observe chlorophyll-a concentrations insurface water, which is an indicator of the total
phytoplankton biomass; however, errors arelarge in coastal areas due to complex water andatmospheric optical properties. The frequency ofnegative remote sensing reflectance (the ratio of
the radiance from the water and the input
irradiance) at 412 nm measured by the satellite
sensor MODIS is shown in Fig. 2 for the
Ise/Mikawa Bay. High frequency was observed inspring and fall, and the frequency in a large area
was greater than 80%. It is believed that theFig. 2. Frequency of negative remote sensing

cause of the negative remote sensing reflectance is related to the presence of absorptive aerosols. In
this study, we developed a method of atmospheric correction using optical properties in the in situ
water and reduced the error of the in-water algorithm estimating chlorophyll-a to make an accurate
chlorophyll-a dataset in the Ise/Mikawa Bay. Making further improvements in the atmosphericcorrection algorithm is critical to better evaluate the influence of absorptive aerosols

Introduction to Division for Chronological Research
Short- and long-term forecasts of global environmental changes and their countermeasures areissues of great urgency. Determining when an event occurred in the past, “dating,” is of great
importance to predict future states of the Earth. Therefore, we conduct chronological studies on abroad range of subjects from events in Earth’s history spanning approximately 4.6 billion years, toarcheological materials, cultural properties, and modern cultural assets.
The Tandetron dating group conducts interdisciplinary research that involves radiocarbon (14C)
dating using accelerator mass spectrometry (AMS) to understand changes in the Earth’s
environment and the cultural history of humankind from approximately 50,000 years ago to thepresent day; the group also conducts R&D on new methods of 14C analysis and dating. In addition,
the group studies near-future forecasts of Earth and space environments, focusing on
spatiotemporal variations in cosmogenic nuclides, such as 14C and 10Be, and conducts research that
integrates art and science through collaborations between researchers in archeology, historicalscience, and other fields.
The micro-scale spatial dating group uses CHIME (the chemical U-Th total Pb isochron method),which was first developed at Nagoya University, to shed light on events in Earth’s history from theformation of Earth 4.6 billion years ago up to approximately 1 million years ago. With an electronprobe microanalyzer (EPMA), non-destructive microanalyses of rocks and other samples are
performed to reveal records of complex events recorded in zircon, monazite, and other materials.
Main Achievements in FY2015
1. Changes in the 14C Contents in Environmental Samples
Since 1983 we have measured the 14C content in pine needles at Nagoya
University to study changes in the atmospheric 14C within an urban area.
The sample values are significantly lower than global estimates based on
14C in the CO2 observational data at Mauna Loa, Hawaii, confirming local

increases in 14C-free CO2 caused by the heavy use of fossil fuels. We also
examined regional characteristics and sources of PM2.5 aerosols in urban,
suburban, and mountainous areas based on 14C in carbonaceous aerosols in
the atmosphere. In addition, we detected foreign aerosols entering Japan
from neighboring countries.

2. Attempts to Reconstruct Paleoclimates from 14C in Stalagmite
The 14C content in stalagmite is diluted by 14C-free (dead) carbon derived from thelimestone bedrock. To quantitatively interpret the 14C in stalagmite, we investigated
14C in drip water in the Ryugashi Cave in Shizuoka Prefecture, Japan, over a span of

two years. The result shows a correlation between the precipitation amounts and the
14C in the drip water, illustrating a trend of higher 14C in drip water during periods ofCollecting a sample of drip

high precipitation. Therefore, 14C in stalagmite is likely an effective proxy for palaeoclimate reconstructions.
3. AMS 14C Dating of Historical Materials
We focus on materials such as fragments of ancient manuscripts and bronze artifacts andinvestigate methods to determine their ages. The fragments, known as kohitsugire, are valuable

source materials to investigate society in the Heian and Kamakura Periods. However, included withthe genuine kohitsugire are numerous counterfeits and copies created later. Therefore, we areworking to reveal the ages of kohitsugire, and, in turn, their historical value.

4. Growth Histories of Rocks and Minerals through a Combination of EBSD and EPMA
Understanding the formation processes of minerals is essential forinterpreting the “age” from a geoscientific viewpoint. We combined two
methods of electron backscatter diffraction (EBSD) and EPMA and appliedthem to metamorphic and deformed rocks to examine their metamorphic anddeformation histories. The garnet shown in the right figures appears to havegrown as a single crystal based on its chemical composition information;
however, the EBSD data reveals a polycrystalline garnet composed of fourdomains with different crystallographic orientations, forcing us to significantly
alter our interpretation of its growth process.

5. Ultratrace Titanium in Zircon with High Precision

U-Pb dating was used on zircon in Toki granite to define the period of zircon crystal growth, while EPMA
was used to measure the formation temperature of the dated region with high precision. The study succeeded
in measuring titanium concentrations of approximately 10–20 ppm with less than a 10% relative error (2σlevel). The zircon can be divided into two types with different crystal growths and different formation times.
6. Developing a Simple Fixed Dead Time System for EPMAIn quantitative EPMA analyses of trace elements, it is necessary to detect very weak X-rays atlarge currents. However, the X-ray strength is extremely high when measuring standard materials
at large currents. Because dead time inherent in X-ray detectors can lead to counting losses, theaccuracy of the dead time correction is indispensable for accurate quantitative EPMA analyses. We
developed a simple fixed dead time circuit designed specifically for quantitative EPMA analyses.
7. Making a Nationwide Spatial Distribution Map of Sr Isotope Ratios
We are making a nationwide spatial distribution map of strontium isotope ratios (87Sr/86Sr) using <180µm stream sediments to detect the producing area of crops and ancient human migrations. Our studies
have demonstrated that information on the origin of biological samples can be predicted from 87Sr/86Sr in
the exchangeable fraction, while geological information of drainage basins can be estimated from 87Sr/86Srin bulk stream sediments.

Introduction to CICR
The Center for International Collaborative Research (CICR) was established in October 2015 to promoteinternational collaborative research to understand the physical mechanisms of phenomena occurring in thespace–Sun–Earth environmental system and their interactions with each other. CICR uses leadership to
encourage and promote internationally coordinated programs, such as those carried out by SCOSTEP and
Future Earth, ground-based observation networks, international satellite projects, hosting international
workshops and conferences, international exchange of foreign and Japanese researchers and students, andcapacity building in developing counties through training courses and schools. CICR replaces the Geospace
Research Center of the former Solar-Terrestrial Environment Laboratory at Nagoya University.
The cycle 24 of the 11-year solar cycle has had the smallest maximum in the last 100 years, andscientists in solar–terrestrial physics worldwide are greatly interested in this anomaly and its consequencesfor Earth’s environment. Therefore, the Scientific Committee On Solar–TErrestrial Physics (SCOSTEP)
under ICSU started a 5-year international program in 2014 entitled “Variability of the sun and its
terrestrial impact (VarSITI)”. One of the co-chairs of the VarSITI program belongs to CICR and is
responsible for leading this program. Therefore, CICR publishes the VarSITI Newsletter every threemonths, operates the VarSITI mailing list, which currently contains more than 700 VarSITI members from
more than 60 countries, and coordinates international symposiums related to VarSITI. CICR also
contributes to other international programs related to the space–Sun–Earth environment, such as Future
Earth and iLEAPS. Related to these international programs, CICR also takes part in/operates
ground-based observation projects, i.e., the EISCAT radar project, Optical Mesosphere Thermosphere
Imagers (OMTIs), the ISEE magnetometer network, the SuperDARN radar network including the
Hokkaido HF radars, the ISEE VLF/ELF network, and the ArCS operation office.
In addition, CICR is preparing international collaborative research programs, 01) the Joint Research
Program (International), 02) the ISEE International Joint Research Program (applicable only to foreign
researchers), and 03) the ISEE/CICR International Workshop, as well as introducing new foreign appointed
professors. These new programs and positions were started in the 2016 fiscal year. The ISEE/CICR
international workshop is intended to provide a comprehensive discussion on a focused topic with 10–15
attendees for one week and will summarize the results in international journal papers and/or books.
In addition to these activities, CICR maintains four domestic observatories at Moshiri, Rikubetsu, Fuji,
and Kagoshima, which make observations of solar wind, the geomagnetic field, and the upper atmosphere,
as well as VLF radio waves. Some of these observations have been conducted for over 30 years.

Introduction to COSO
Because the research subjects of ISEE encompass natural phenomena over a wide region ranging
from the Earth's surface to outer space, COSO is expected to perform empirical and advanced researchby observation. In particular, collaborations between industry, academia, and government have led toremarkable technological developments in observations by aircraft, balloons, sounding rockets, andspacecraft. We develop and implement innovative observation projects for orbital and suborbital
observations and also promote technological developments in these fields.
COSO plays a key role in aircraft observations in Japan and promotes aircraft observations of
the Earth in cooperation with other organizations. We also investigate and promote future space
exploration missions in collaboration with institutions in Japan and overseas to gain new insights
into physical phenomena. We help to advance observation capabilities for future orbital andsuborbital observations by developing an efficient common technological and development
environment via interdisciplinary activities. In addition, the Hydrospheric Atmospheric ResearchLaboratory in COSO contributes aircraft/balloon observations and satellite observations via two Xand Ka-band radars, together with observational and numerical model studies related to the VL.
Details about ongoing projects and technological developments in COSO are as follows: (1) We plan
to establish a central base for aircraft observations at this center, which will lead aircraft
observations in Japan and also implement aircraft observations of phenomena such as typhoons. (2)We use comparatively small balloons and are working on the development of devices for measuring
the distribution of concentrations of the greenhouse gas CO2 as far as 10 km above the ground. A
balloon-borne CO2 sonde can function regardless of the location, even when there are clouds. (3) We
promote the ERG satellite mission, which is an exploration project being developed at the
JAXA/ISAS. The ERG satellite will be launched and start observations in 2016. COSO has
contributed to the development of the space plasma particle analyzers onboard the ERG satellite.
(4) ChubuSat-2, which is a 50-kg microsatellite designed to observe solar neutrons, was launched in
February 2016. (5) COSO also plans the world's first exploration project for performing
state-of-the-art measurements with high temporal and spatial resolution for space physics by aformation flight of a number of spacecraft in the ionosphere/magnetosphere of the Earth's polar

Project for Solar–Terrestrial Climate Research
Solar activity, which corresponds to the sunspot number, has an 11/22-year cycle. However, it
undergoes long-term variability on cycles ranging from decades to several thousands of years.
Because long-term solar activity has coincided with variations in the terrestrial climate over several
thousands of years, many researchers have reported that long-term solar activity, as well as volcanic
activity, may be one of the causes of natural climate variability. In particular, the years between the1650s and the 1700s are known as the Maunder Minimum, during which time the sunspot number
was significantly lower than the mean and the terrestrial climate was reported to have fallen into theso-called Little Ice Age.
However, the physical processes by which solar activity affects terrestrial climate variations is notvery clear. Therefore, understanding this physical process is not only one of the main scientific issues
in solar–terrestrial environmental research but it also contributes to our understanding of thecurrent climate warming trend, as well as our ability to predict climate variations in the near future.
Because the current solar activity (cycle 24) is considered to be the lowest in the last few decades,
most solar–terrestrial environmental researchers believe that solar activity may be shifting into aquiet phase in the near future. Therefore, revealing how solar activity affects the terrestrial climate
in the 21st century is an important issue both scientifically and socially.
This research project aims to reveal how solar activity affects the terrestrial climate andenvironment via a collaboration of researchers from fields such as solar physics, meteorology,
oceanography, paleoclimatology, space physics, and cosmic-ray physics. This collaborative research
focuses on the following issues, which will be studied by both domestic Japanese and international
researchers:
1. Paleoenvironmental and solar activity data from the past will be reconstructed at high resolution
using tree rings, ice cores, and permafrost.
2. Nitrogen oxides and hydroxide, both of which are produced by intrusions of high-energy charged
particles (i.e., galactic cosmic rays) accelerated by solar flares into the atmosphere, will bemeasured over the Antarctic.
3. The physical mechanisms of variations in sunspot number will be revealed via numericalsimulations compared to observation data. Based on this analysis, total solar irradiance in the
recent past, as well as in the near future, will be projected along with terrestrial climate change.
4. The effects of solar radiation, high-energy charged particles, and cosmic rays on the terrestrial
climate and environment will be analyzed using several Earth system models. Future projectionsof such effects will also be actively performed.

7-3. Projectfor Space–Earth Environmental Prediction
Over the past 50 years, space exploration has expanded rapidly and has now reached past theedge of the heliosphere. Consequently, it is known that solar activity and the dynamics of the spaceenvironment can significantly impact human socio-economic systems as well as the global
environment. For example, the giant solar flare observed by the British astronomer Richard
Carrington in 1859, called the Carrington Event, caused powerful magnetic storms. If such an event
occurred in the modern era, power, satellite, aviation, and communication networks would possibly
suffer damage on a global scale. Moreover, analyses of the latest stellar observations and of
cosmogenic isotopes in tree rings suggest the possibility of even larger solar flares. However, themechanisms of the onset of solar flares and their subsequent processes have not yet been fully
explained. Therefore, modern society is at a risk from severe space weather disturbances, which arecaused by such solar explosions, and understanding and predicting variations in the space–Earthenvironment is both a scientific subject and a crucial issue for modern society. Further, because theaccurate prediction of complex phenomena is a common problem in science, this is also a crucial
subject for various scientific disciplines. The Project for Space–Earth Environmental Prediction is a
new joint research project aimed at synergistically developing our predictive capability for the
space–Earth environment through the cooperation and interaction of solar physics, geomagnetismand space sciences, meteorology, climatology, space engineering, and other related fields. This
project addresses the various issues shown in the figure below based on the ISEE Collaborative
Research Programs and the support of a Grant-in-Aid for Scientific Research on Innovative Areas
from MEXT/Japan “Project for Solar-Terrestrial Environment Prediction (PSTEP).”

Project for the Interaction of Neutral and Plasma Atmospheres
The Earth’s atmosphere is partly ionized due to solar ultraviolet emissions forming theionosphere. Ionospheric plasma affects human activities in space, such as radio communicationsand GPS positioning. The significant consequences of climate change appear in the upper
atmosphere and ionosphere. As shown in the figure below, the neutral–plasma interaction processes
in the upper atmosphere and ionosphere can be observed as various phenomena occurring fromhigh to low latitudes. The aurora in the polar region is caused by precipitation of high-energy
plasma, which heats the upper atmosphere and generates atmospheric waves and disturbancesthat propagate toward low latitudes. Conversely, ionospheric plasma instabilities, which are calledplasma bubbles, occur in the equatorial upper atmosphere, causing interference in satellite–groundcommunication and GPS positioning. These phenomena can be measured by various ground-based
remote-sensing instruments, such as airglow imagers, magnetometers, radars, lidars, andmillimeter-wave telescopes. This interdisciplinary project investigates the interaction of neutral
and plasma components of the Earth’s atmosphere using various ground remote sensing techniques
and in situ satellite measurements, as well as global and regional high-resolution modeling of theneutral–plasma interaction, and contributes to dependable human space activities.

Project for Cloud and Aerosol Processes
Hydrometeors and aerosols closely interact with each other in their generation and dissipationand play important roles in the atmospheric water circulation and the earth’s radiation budget.
They are, however, some of the most unknown quantities in the atmosphere. So far, hydrometeors
and the related circulation of water have been studied in the Hydrospheric Atmospheric ResearchCenter, whereas aerosols and related processes have been studied in the Solar–Terrestrial
Environmental Laboratory. In the joint research program, researchers from both sides will
cooperate to study the interaction between aerosols and hydrometeors, their variations in theformation of precipitation, and cloud–aerosol–radiation interactions using laboratory experiments,
field observations, and numerical simulations. On the basis of field observations, the numericalmodel will be improved for quantitative simulations of cloud and aerosol processes. In cooperation
with the Center for Orbital and Suborbital Observations, we will make in situ observations of
typhoons using an aircraft, balloons, and drones. This research will improve the cloud-resolving
model (CReSS) and the impact of aerosols on typhoon clouds will be studied. The present program
will interact with the other program on solar climate impacts to study the formation of clouds inassociation with cosmic rays.

9. Education

9. Education
The Institute for Space–Earth Environmental Research primarily offers graduate programs inthree schools, i.e., Science, Engineering, and Environmental Studies; however, it also provides
opportunities for both undergraduate and postdoctoral experiences in these schools. In addition to theacademic staff of the faculties, specially appointed members also contribute to education via graduate
and undergraduate courses. Graduates are enrolled in the doctoral programs. Academic members are
responsible for guiding the progress of the students’ thesis projects. The students studying at theinstitute also have opportunities to attend seminars and discussions with foreign researchers and toparticipate in international meetings/conferences and observations/experiments.
Graduate Programs
The institute has its own graduate course program for Heliospheric and Geospace Physics as a partof the Division of Particle and Astrophysical Science in the Graduate School of Science at Nagoya
University.
In addition, it cooperates with the Department of Electrical Engineering and Computer Science via
the Space Electromagnetic Environment group (http://www.nuee.nagoya-u.ac.jp/soshiki/electrical-e.php)
in the Graduate School of Engineering and the Department of Earth and Environmental Sciences (as agroup in the Earth and Planetary Sciences Course and the Hydrospheric–Atmospheric Sciences Course
http://www.env.nagoya-u.ac.jp/english/dept/index.html) in the Graduate School of Environmental
Studies by teaching/training graduate students in disciplines related to Space–Earth Environmental
Research. Graduates are enrolled in the doctoral programs. Academic members are responsible for
guiding the progress of the students’ thesis projects. They also teach core and topical courses.

11. Outreach
Public lectures, open lab., and school visits (October, 2015 – March, 2016)ISEE members have contributed to the public education through 13 lecture visits, 4 public
lectures in the university, 3 open laboratory events, 6 receipts of the high-school students’ visits.
ISEE and former STEL have continued a close relationship with the Rikubetsu town in Hokkaido
since 2003. A public lecture and experiment were held on 13 Nov. at the Rikubetsu elementary andjunior-high school. Another public experiment took place on 14 Nov. at the Rikubetsu Space Earth
Science Museum. From 22 to 29 Nov. ISEE hosted a visit of 24 high-school students and teachers
from Finland.

They learnt research topics at ISEE and visited other facilities in the Nagoya

university and also a facility of the Kyoto university.
ISEE distributes series of booklet to answer 50 questions and comics related to the space–Earthenvironment for public.
The website of ISEE (http://www.isee.nagoya-u.ac.jp/) continues to publish the most up-to-date
activities and outcomes of the laboratory to public.
