2. Topics
2.1. Masterplan 2017
Research Institute for Sustainable Humanosphere (RISH), Kyoto University, National Institute of Polar
Research (NIPR), Institute for Space-Earth Environmental Research (ISEE), Nagoya University, andInternational Center for Space Weather Science and Education (ICSWSE), Kyushu University proposed
the research project “Coupling process in the solar-terrestrial system” (PI: Prof. Toshitaka Tsuda at RISH,
Tsuda et al. [2016]) to Masterplan 2017 of Science Council of Japan (SCJ). This is a project to study thesolar energy inputs into the Earth, and the response of Geospace (magnetosphere, ionosphere andatmosphere) to the energy input. We plan to install large atmospheric radars with active phased array
antenna at the equator and the Arctic regions. One is Equatorial MU (EMU) radar by RISH in Sumatera
Island, Indonesia, and the other is EISCAT_3D by NIPR in northern Scandinavia under international
collaborations. We develop the global observation network is planned (ISEE, ICSWSE with otherinstitutions). SCJ announced the Masterplan 2017 on February 8, 2017 (see web page). Our proposal was
selected as one of the important large research projects (in total 28 projects were selected), which is thesame status as in Masterplan 2014. Selection of the Roadmap 2017 of the Ministry of Education, Culture,
Sports, Science and Technology will soon start following this result of Masterplan 2017.

Effectiveness of highly sensitive submillimeter-wave limb sounder in vertical-distribution measurements
of atmospheric chemical compositions, temperature, and wind over a wide altitude range has been
demonstrated by the Superconducting Submillimeter-wave Limb-Emission Sounder (SMILES), which was
operated in 2009-2010 winter on the International Space Station [Kikuchi et al., 2010]. Our proposed new
submillimeter-wave limb sounder boarded on a small satellite will inherit excellent highly-sensitive
superconducting sensor technology of SMILES and will provide precise measurement of vertical
distribution of compositions, temperature, and wind, but extremely extend the altitude coverage andvariety of observing targets by implementing multi-frequency band receiver including THz channel. The
proposed sounder will be outstanding at measurement precision and altitude coverage in comparison withother currently planned satellite missions.

3. Research Report
3.1. Report from National Institute for Polar Research (NIPR)(Yasunobu Ogawa, NIPR)=== Recent research activity related to PANSY ===A 1-year continuous full system observation of the PANSY radar has been successfully conductedfrom late September 2015 through September 2016. This is the first MST radar data in the world
covering a whole year continuously. It will enable us to capture various temporal- and spatial-scale
phenomena in the Antarctic troposphere, stratosphere and mesosphere with high temporal and verticalresolution throughout the year and to contribute to improving global climate models for better
understanding of future climate change.
In addition, the second Interhemispheric Coupling Study by Observations and Modeling (ICSOM: seedetails at http://pansy.eps.s.u-tokyo.ac.jp/icsom/) campaign was successfully conducted from January
22 to February 28, 2017. International collaborative studies based on the first and second ICSOM
campaigns are ongoing. It is expected that these international collaborations including the PANSY
radar will promote a more accurate understanding of the Antarctic atmosphere and interhemisphericcoupling processes.

3.2. Report from Institute for Space-Earth Environmental Research (ISEE), Nagoya University(Satonori Nozawa, Nagoya University)=== Research topics ===A new scenario is presented for the cause of magnetospheric relativistic electron decreases (REDs) andpotential effects in the atmosphere and on climate. High-density solar wind heliospheric plasmasheet(HPS) events impinge onto the magnetosphere, compressing it along with remnant noon-sector outerzone magnetospheric ~10-100 keV protons. The betatron accelerated protons generate coherent
electromagnetic ion cyclotron (EMIC) waves, which interact with relativistic electrons and cause therapid loss of these particles to a small region of the atmosphere. A peak total energy deposition of ~3 ×
10^20 ergs is derived for the precipitating electrons with a maximum energy deposition and creation ofelectron-ion pairs at 30-50 km and at<30 km altitude. We focus the readers' attention on the relevanceof this present work to climate change mechanisms.

3.6. Report from Tohoku University(Takeshi Sakanoi, Tohoku University)=== Symposium===
The 18th symposium on planetary science 2017 was held in Sendai on February 20-22, 2017. The
symposium concerned the following topics: atmospheres and magnetospheres on terrestrial and Jovian
planets and their satellites studied by observations and numerical analyses, and development of new
observational and computational approaches. Invited talks and discussions were held relating toplanetary explorations by Akatsuki, Juno and Hisaki etc. and to future planetary and satellite missions.
=== Summary of the research ===< Gravity wave in the mesopause region>
Perwitasari et al. (2016) reported a statistical study on concentric gravity waves (CGWs) in themesopause (~95 km) using 3 years nightglow data obtained by Ionosphere, Mesosphere, upper
Atmosphere and Plasmasphere/Visible and near-Infrared Spectral Imager. The 235 CGWs events were
found with horizontal wavelength ranging from 40 to 250 km and maximum radius of 200 to 3000 km.
The latitudinal distribution of the CGWs centers had peaks in mid latitude (40°N and 40°S) andminimum at low latitudes (10°S). More events were found in the summer hemisphere midlatitudes,with a rapid transition between northern and Southern Hemisphere around the equinoxes.
<Small-scale auroral dynamics>
Nishiyama et al. (2016) observed mesoscale pulsating aurora aurora (100 km × 100 km) with patchy
structure and equatorward propagation. Fast Fourier transform (FFT) analysis revealed that thispulsating patch clearly exhibited temporal variations that can be categorized into two types: on-off
pulsation (7.8–10 s) with large amplitudes and luminosity modulations excited during on phase with afrequency of about 3.0 Hz. In addition, they applied principal component analysis (PCA) to time series
image data of the pulsating aurora for the first time. Time coefficients were estimated by PCA for thewhole patch and the substructures were consistent with those obtained from the FFT analysis, andtherefore, they concluded that PCA is capable of decomposing several structures that have different
coherent spatiotemporal characteristics.
<Radiation belt>
Kato et al. (2016) carried out a self-consistent simulation of the generation process of whistler-mode
chorus by a spatially one-dimensional electron hybrid code, by assuming the magnetic field
inhomogeneity corresponding to L = 4 of the dipole field. Chorus emissions with rising tones are
reproduced in the simulation result, while the frequency range, sweep rate, and the amplitude profiles
in the spectra of the reproduced elements are consistently explained by the nonlinear wave growththeory. Kitahara and Kato (2017) report the application for the Wave-Particle Interaction Analyzer(WPIA) on the Arase (ERG) satellite which was launched successfully in December 2016, whichmeasures the relative phase angle between the wave magnetic field vector and the velocity vector ofeach particle and calculates the energy exchange from waves to particles. They expand its applicability
by proposing a method of using the WPIA to directly detect pitch angle scattering of resonant particles
by plasma waves by calculating the g values.
< Planetary sciences>
IPRT (Iitate Planetary Radio Telescope) is a ground-based VHF-UHF radio telescope developed by
Tohoku University, which has been developed at the Iitate observatory in Fukushima prefecture Japan
since 2000 and dedicated for the observations of solar and planetary radio emissions. IPRT has two
distinctive radio receivers; one is a low noise and quite stable receiver tuned at 325MHz and 785MHz,
and another one is a 100-500MHz spectro-polarimeter, named AMATERAS (the Assembly of Metric-5

資料8-G

band Aperture TElescope and Real-time Analysis System). The former is mainly used for observing
Jupiter’s synchrotron emission with the sensitivity of 0.1Jy, and enables us to investigate dynamicalvariations of Jupiter’s deep inner magnetosphere. The latter is used for observing solar radio bursts
with 10ms accumulation time and 61 KHz bandwidth, and enables us to clarify various micro structureof wave-particle or wave-wave interactions generated in the solar corona region.
The Jovian and solar radio wave receiver system in HF range (15-40MHz) was continuously operated
at Iitate Observatory of Tohoku University. Spectrograms of Jovian and solar radio wave with a time
resolution of 0.5 sec were automatically archived and provided to the researchers through the internet.
The discussion on combining this data archive with that of Nancay observatory has started between the
researches of Paris Astronomical Observatory and Tohoku University. In addition, the operation of RF
waveform recording receiver system for the observation of Jovian decametric S-bursts was started at
Iitate Observatory since October 2013. The data will be useful for the analysis of the repetition of Sbursts, which is caused by Jovian Ionospheric Alfven Resonator (IAR).
Sakanoi et al. (2017) reported specifically designed instruments on 40 and 60cm telescopes on Mount
Haleakala, Hawaii, to study phenomena such as volcanic activity on Io and exoplanetary polarization.
For continuous monitoring of planetary atmospheres by the telescope at Haleakala, Nakagawa et al.
(2016) developed a new Mid-Infrared Laser Heterodyne Instrument (MILAHI) with >106 resolving
power at 7–12 μm. Room-temperature-type quantum cascade lasers (QCLs) that cover wavelength
ranges of 7.69–7.73, 9.54–9.59, and 10.28–10.33 μm have been newly installed as local oscillators toallow observation of CO2, CH4, H2O2, H2O, and HDO. They also showed scientific capabilities andmeasurement sensitivities of the MILAHI using a model with radiative transfer code.
For Matian atomosphere, Terada et al. (2017) revealed gravity wave-like perturbations in theMartian upper thermosphere observed by the Neutral Gas Ion Mass Spectrometer (NGIMS) onboard
the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. The amplitudes of small-scale
perturbations with apparent wavelengths between ~100 and ~500 km in the Ar density around theexobase show a clear dependence on temperature (T0) of the upper thermosphere. The average
amplitude of the perturbations is ~10% on the dayside and ~20% on the nightside, which is about 2
and 10 times larger than those observed in the Venusian upper thermosphere and in the low-latitude
region of Earth's upper thermosphere, respectively. Kuroda et al. (2016) carried out simulations with a
new high-resolution Martian general circulation model (MGCM) (T106 spectral resolution, or ~67-km
horizontal grid size) to reveal global distributions of gravity waves (GWs) during the solstice andequinox periods. They showed that shorter-scale harmonics progressively dominate with height, andthe body force per unit mass (drag) they impose on the larger-scale flow increases. GW energy in the
troposphere due to the shortest-scale harmonics is concentrated in the low latitudes for both seasonsand is in a good agreement with observations. Terada et al. (2016) develop a one-dimensional fullparticle model of the Martian upper thermosphere-exosphere, where the Direct Simulation Monte
Carlo (DSMC) method is applied to both thermal and non-thermal components. Their full-particle
model can self-consistently solve the transition from collisional to collisionless domains in the upper
thermosphere, so that the energy deposition from non-thermal energetic components to thermal
components in the transition region is properly described.
Masunaga et al., (2017) examined Venusian EUV dayglow using the Hisaki data. They showed that ∼4-day periodic variations are detected and are dominant on the dawnside of Venus. The ∼4 day
periodic dayglow variations may reflect atmospheric dynamics of Venus. For Jupiter aurora, Kita et al.
(2016) reported the statistical relationship between the total power of the Jovian ultraviolet aurora andthe solar wind properties found from long-term monitoring by the spectrometer EXCEED on board theHisaki satellite. Superposed epoch analysis indicates that auroral total power increases when an
enhanced solar wind dynamic pressure hits the magnetosphere.
