The 32nd Assembly of Intergovernmental Oceanographic Commission (IOC)Yutaka Michida, Professor, Center for International Collaboration

The 32nd Assembly of the Intergovernmental Oceanographic Commission (IOC) was conducted as an in-person
meeting from June 21 to 30, 2023 at the UNESCO Headquarters in Paris. At the 55th session of the Executive Council ofthe IOC held in 2022, all Member States of the Executive Council were requested to have a maximum of four attendees intheir delegations to prevent the further spread of COVID-19, and no restrictions were imposed on the number of delegatesto the session in 2023. Prof. Yutaka Michida, the Director of the Center for International Collaboration (CIC) of AORI,
participated as the head of the Japanese delegation. Professors at the CIC, namely, Hiroaki Saito, Mitsutaku Makino, andNaomi Harada, also joined the meeting as part of the delegation. In addition to the four professors, representatives of the
Ministry of Education, Culture, Sports, Science and Technology (MEXT), Japan Meteorological Agency (JMA), Japan
Coast Guard (JCG), and Japan Agency for Marine-Earth Science and Technology (JAMSTEC) also participated.
The Assembly adopted four resolutions as follows,
IOC Resolution A-32/1: Establishment of an IOC Sub-Commission for the Central Indian Ocean (IOCINDIO);IOC Resolution A-32/2: Improving Climate Observations;
IOC Resolution A-32/3: I mplementation of the United Nations Decade of Ocean Science for Sustainable Development(2021–2030);
IOC Resolution A-32/4: Governance, Programming, and Budgeting Matters of the Commission.
With the first IOC Resolution A-32/1, the Commission decided to establish a regional sub-commission for the Central
Indian Ocean (IOCINDIO) by upgrading theregional committee for the Central Indian
Ocean after intensive discussions among
Member States and with existing neighboring
Sub-Commissions. IOCINDIO is the fourth
IOC sub-commission, in addition to thethree Sub-Commissions for the Caribbean
Ocean, Western Pacific, and Africa. This willplay a key role in promoting ocean science,

between the atmosphere and ocean, disaster prevention/mitigation measures to deal with such extreme climate events,
and pressing social issues. Within this context, the need for a new approach to study meteorological phenomena has
become increasingly important. Moreover, academia is also expected to promote the UNDOS through collaboration
among domestic and international researchers. Therefore, the Atmosphere and Ocean Research Institute hosted this
symposium to discuss how we, as a research community, can contribute to and promote the UNDOS by 2030. In addition
to the Oceanographic Society of Japan, the symposium was supported by the Ocean Policy Society of Japan, Fisheries
Society of Japan, and Japanese Society of Fisheries Oceanography.
The symposium comprised two parts: lectures in the first half and a panel discussion in the second half. The firsthalf of the symposium featured lectures by 22 experts from various fields in Japan, including atmospheric and oceanic
sciences, marine biology, fishery sciences, social sciences, and engineering. The lectures were interwoven with the sevensocial goals of the UNDOS (a clean ocean, healthy and resilient ocean, a productive ocean, a predicted ocean, safe ocean,an accessible ocean, and an inspiring and engaging ocean) and introduced cutting-edge research that could contribute to
any of these goals.
Throughout the two days of the sessions, I was struck by the fact that many symposium speakers, who are experts
in various fields, such as atmospheric and oceanographic sciences, social sciences, engineering, and earth sciences,emphasized the contribution of their research to “a predicted ocean.” In the panel discussion, participants discussed how
the community can and should contribute to UNDOS by 2030, in cooperation with each other. The following questions
were addressed: how to build partnerships with people outside of one’s field of expertise; what is Japanese-style“sustainability;” how to create a lenient network; how to change those who are indifferent to the "ocean" into those whoare interested in it, and how to involve them; and how can conflicts of interest be balanced. Some participants suggested
continuing the symposium, namely, developing it into an international symposium with overseas participants, which weplan to conduct in the future.
In addition to the 100 participants who attended the symposium at the venue and online through Zoom, some viewers
watched the live stream on YouTube, indicating that although the symposium was intended for specialists, many ordinary
people also participated. Videos of each presentation are available on YouTube (https://www.youtube.com/channel/

PICES Annual Meeting, 2023, Seattle
Mitsutaku Makino, Professor, Center for International Collaboration

PICES-2023 was held from October 23 to 27, 2023 in Seattle, Washington State, on the West Coast of the UnitedStates. It owes its name to Native American leader Seattle, the chief of the Duwamishes, Suquamishes, and other tribesof the Puget Sound area. This area is famous for its great natural beauty and for the most advanced IT companies, suchas Microsoft and Google. Many researchers enjoyed coffee from Seattle, such as that from Starbucks, which opened its
first shop near the fish market. The meeting was hosted by National Oceanic and Atmospheric Administration (NOAA)
in coordination with the Secretariat of The North Pacific Marine Science Organization (PICES), and many brilliant
presentations and discussions were conducted to assess the progress of PICES and set a path for the remaining period of
the United Nations Decade of Ocean Science for Sustainable Development until 2030.
After the COVID-19 pandemic, many ocean scientists in the Pacific conducted face-to-face discussions. PICES-2023
is the largest annual meeting ever conducted. A total of 672 attendees, including 76 virtual participants, participated in
the meeting. Remarkably, there were 244 early career ocean professionals (ECOPs) in-person participants and observers
from 20 international and regional organizations and programs. We organized 19 Science Board/topic/paper sessions, 11
workshops, and 22 business meetings. The meeting was paperless (which has currently become the tradition of PICES),
and participants were encouraged to use the Whova app to access the updated schedules, communicate with each other,and make announcements from organizers.
The PICES Chair Award is awarded to individuals who have contributed significantly to our organization. This year,
it was awarded to Dr. Robin Brown (Canada) for his sustained dedication to the scientific activity and administrationof PICES. The Wooster Award was awarded to Dr. Steven J. Bograd (USA) for his long-term and ongoing excellencein the research and teaching of North Pacific marine science. The PICES Ocean Monitoring Service Award (POMA)
was awarded to the Chinese Harmful Algae Bloom Monitoring and Research Program. Finally, the Zhu-Peterson

Prof. Shoshiro Minobeemphasized the importance of advancing our capacity for marine biological forecasting for the success of the UN Decadeof Ocean Science, for which one of seven desired outcomes is “A Predicted Ocean.” This other topics of this year’s
sessions focused on deep learning, extreme weather, climatic events, small pelagic fish and extreme events, anticipatedand realized effects of climate change, non-indigenous species, emerging pollutants, and seamount diversity.
One of the impressive activities of PICES-2023 was the mentoring program. A total of 26 mentor-mentee pairs weredeveloped based on their background information and preferences. The program was largely successful and beneficial forboth mentors and mentees. This will boost the engagement opportunities of ECOPs in PICES. AP-ECOP members haveagreed to continue this scheme as one of the top priorities for 2024.

JSPS Core-to-core Project CREPSUM
Hiroaki Saito, Professor, Center for International Collaboration

AORI has spearheaded international collaboration and activities between Japan and Southeast Asian (SEA) countries
over the past two decades. One of the leading initiatives was a multinational research and education program fundedby the Japan Society for the Promotion of Science (JSPS). In autumn 2019, AORI launched a new JSPS project called
Collaborative Research and Education Project in Southeast Asia for Sustainable Use of Marine Ecosystems (CREPSUM),
which began in spring 2020. Over 200 scientists have since gathered under CREPSUM, hoping to achieve the following
transdisciplinary goals: 1) establish an international science and educational network for SEA marine ecosystems; 2)develop marine ecosystem studies to address emergent issues in conservation and achieve the sustainable use of SEA
marine ecosystem services; and 3) contribute to the UN Decade of Ocean Sciences (Ocean Decade) and UN SDG 14: Life

below water efforts by imparting thebest scientific knowledge on marine
ecosystems.
Un for t u nately, t he a nt icipatedlaunch of the CREPSUM coincidedwith the global COVID-19 pandemic.
Until the summer of 2022, most planned
field research activities and training/educational courses were canceled.
Under difficult conditions, CREPSUM
scientists have made substantial efforts
t o s u m m a r i z e p a s t c ol l a b o r a t ive
studies by publishing review papers
and field guides, as well as conducing
online workshops and seminars. This
Fig. 1 Group photo of CREPSUM Joint Seminaris because of the rapid developmentof online meeting technologies. From the autumn of 2022, we gradually resumed field studies and seminars, but still
had difficulty traveling and obtaining permission for field studies owing to the repeated waves of COVID-19 infection.
Consequently, most field and laboratory studies have been conducted in each member country. We shared obtained
results in online meetings. However, with the increase in new findings, we believed that in-person meetings should beheld to further understand the findings and foster inspiration to develop new ideas and strategies for the sustainable useof marine ecosystem services in SEA countries.
On March 8-9, 2023, we held the CREPSUM Joint Seminar at the Atmosphere and Ocean Research Institute, theUniversity of Tokyo. A total of 38 and 25 scientists from five SEA countries and Japan, respectively, were invited.
The symposium began with a welcome speech from Prof. Tomohiko Kawamura, the director of AORI, followed by an
introductory keynote titled Marine ecosystem studies in the southeast Asia: Collaborative scientific activities for thesustainable use of ecosystem services by the project coordinator Prof. Hiroaki Saito. Subsequently, we conducted a photosession (Fig. 1) and offered a coffee break. At the coffee break, many voices of joyful greeting echoed in the venue, andconsequently, the resumption of the symposium was slightly delayed. This “rescheduling” was necessary to celebrate
our reunion. Thereafter, the symposium was resumed by country reports from National Coordinators, and reports fromresearch groups and individual scientists. We shared novel findings of the status and change in SEA marine ecosystems,
and also discussed various activities to disseminate scientific knowledge to the general public and/or decision makers.
These activities are expected to achieve the goals of the Ocean Decade. Notably, many excellent studies were reported byearly career scientists. They are going to be future leaders of marine ecosystem studies after the Ocean Decade (2030) as
the significant influence of global change on marine ecosystems and our society will continue even after 2030.
At the symposium, we recognized that our scientist network developed under JSPS projects, including CREPSUM.
This is essential for the sustainable use of marine ecosystem services in the Anthropocene as our goals are too large tobe achieved by one country alone. Prof. Saito stated that AORI would launch the Section for Research Alignment with
Southeast Asia (SERASEA) in April 2023, which would realize joint research between SEA countries and Japan. We aim
to use SERASEA as a platform for joint research and education activities to achieve the goals of the Ocean Decade and
UN SDG14 Life below water.

of Education, Culture, Sports, Science and Technology, Japan (Top Global University Initiatives of MEXT), andAtmosphere and Ocean Research Institute (AORI). More than 15 students from ANU have studied various aspects ofgeohazards, including science, technology, and social sciences, along with UTokyo students.
Participants from ANU were from the Research School of Earth Sciences and Center for Public Awareness of
Science (CPAS), and the latter is concerned with science communication, whereas the UTokyo students came fromthe schools of Science and Engineering as well as Law, Literature and Economics. With such diverse backgrounds, we
expected lively discussions during the group work. The mixed ANU and UTokyo students were divided into five groups
and all activities were conducted accordingly. Students participated in all the discussions and provided daily accounts
that were uploaded to social networking sites, which helped them think deeply about methods to engage with the public.
The students attended lectures at AORI for the first two days
after the opening ceremony, which was held on the second floorof the building. During the opening ceremony (see programme),
the students were warmly welcomed by staff from the Australianand Japanese embassies, directors of the International Education
and Research Offices of both universities, and director of AORI,
Professor Susumu Hyodo. Lectures and lab tours were provided by
AORI professors and staff (Drs. Makino, Takagi, Watanabe, Aze,
Miyairi, myself, and others), along with those from other institutes
within and outside UTokyo (Drs. Sayuda, Sato, Heslop, and Grant).
One of the highlights of this year’s trip was a visit to the
Fukushima Nuclear Power Plant Decommissioning Archive Center,as the release of treated water was worldwide news. The students
realized the importance of science communication, which wasreflected in their final presentations after a two-week trip. We also
visited Ohkawa Elementary School, which was severely affectedby the 2011 tsunami and more than 80 students lost their lives.
Evacuation drills were conducted and the students followed therules; although many casualties were recorded, critical reviews
were conducted and even the local government was taken to court.
According to the reflective diary written by the students, they wereof the same generation as the students of Ohkawa Elementary
School.

The second half of the trip was to Mt. Fuji and its surrounding areas. After a visit to the Fujitsu Research Institutein Kawasaki to learn about the cutting-edge technologies developed by the company, we travelled to Yamanashi and
Shizuoka prefectures. Ecology, culture, geology, tourism, engineering, and social sciences were topics that were studied
and discussed by students through lectures by experts and visits to various sites. Owing to the pleasant weather, thestudents enjoyed climbing the Hoei Crator that strengthened their friendships as they helped each other during theactivity.
We witnessed the fostering of students’ friendships across cultural and language barriers and realized the importanceof this type of activity for this young generation. We are grateful for the support provided by various organizations and
AORI staff for the success of this program.

The 2nd EarthCARE Modeling Workshop, March 27–29, 2023
Masaki Satoh, Professor, Division of Ocean–Earth System Science
Kentaro Suzuki, Professor, Division of Climate System Research

A new satellite called EarthCARE (Earth Clouds, Aerosols and Radiation Explorer) will be launched in May 2024
as a joint European and Japanese mission. The EarthCARE satellite is intended to observe clouds, aerosols, and radiation
processes and improve climate models by better understanding these processes. To enhance collaborative studies
between the EarthCARE observations and modeling, the 2nd EarthCARE Modeling Workshop was conducted on March
27-29, 2023, at Hotel Laforet Shuzenji. The workshop was organized by Profs. Masaki Satoh and Kentaro Suzuki (AORI,The University of Tokyo), Prof. Bjorn Stevens (Max Planck Institute for Meteorology), Prof. Hajime Okamoto (Kyushu
University), and Dr. Takuji Kubota (Japan Aerospace Exploration Agency).
Following the 1st EarthCARE Modeling Workshop held on February 16-18, 2022, this workshop was intended
to enhance the activities of the cutting-edge atmospheric climate and weather models, including “K-scale” or global
storm-resolving models and their collaboration with the EarthCARE satellite. The EarthCARE satellite will provide
the first global observation of the vertical motion of cloud particles from space by CPR (Cloud Profiling Radar) Doppler
measurements). Before its launch, we invited modeling scientists to discuss possible directions and areas of collaboration
between the EarthCARE satellite and modeling communities to enhance the model representations of cloud andconvection physics. We also aimed to facilitate ongoing discussions on NASA AOS (Atmosphere Observing System),
which is planned to launch around 2030.
Approximately 90 experts attended the workshop to discuss the EarthCARE satellite project, satellite simulators,
and cloud and convection processes. After introducing the modelers to EarthCARE and using satellite data for evaluating
global storm-resolving models and conventional climate models, issues related to the evaluation and improvementof cloud, convection, and aerosol processes in models using EarthCARE observational data were discussed in thisworkshop. Rapporteurs prepared daily summary reports based on these discussions.
This workshop was jointly hosted by the International Core-to-Core Project on Global Storm Resolving Analysis(ICCP-GSRA). ICCP-GSRA fosters activities promoting international collaboration for global storm-resolving
meteorological data analysis and their social implementation.

on convection and water cycles and their interactions with weather andclimate. However, the complex nature of relevant scientific issues and the large amount of data pose great challenges
for processing all the information to achieve breakthroughs in such studies. We invited the participants to share recent
research results and jointly synthesize outstanding research outcomes to promote communication and collaboration.
Approximately 50 participants joined the workshop, including 23 students/post-doctoral students and five faculty
members of NTU. Students from AORI and NTU made the agenda and organized the workshop. Mr. Koryu Yamamoto(AORI) and Ms. Chai-Wei Chang (NTU) formed a student convener team and communicated their intention toformulate the program before the workshop. They arranged the abstracts into oral and poster presentations, and a longer
presentation time was given to the PhD students. They also invited all faculty members to conduct presentations on
popular topics or lectures on their specialties. On the afternoon of the second day, students were divided into five splintergroups for intensive discussion on the following topics:
1. Issues in predicting extreme rainfall events.
2. W hat types of satellites or spaceborne sensors are required to advance climate change research?
3. W hat types of geoengineering technology are envisioned for extreme weather events, and what factors should beconsidered when implementing them?
4. W hat factors influence the cloud radiative feedback on global and regional circulation and precipitation?
5. Physically informed machine learning approaches and their application in atmospheric science studies.
Each group summarized the discussions and reported the results on the third day to stimulate further discussions
with all participants.
The next joint workshop between AORI and NTU will be held at NTU in 2025. Although the workshop is intended
to provide an opportunity for interaction between members of both universities, students are encouraged to visit eachother’s universities for short or extended stays. We also encourage students to communicate with each other’s faculty
members to continue their research activities.
For participating students from NTU, AORI provided support in the form of travel fees. We acknowledge the supportof the Virtual Laboratory for the Earth’s Climate Diagnostics Program.

after finishing a master’s course on physicaloceanography at the University of Tokyo in
1983. During my service as a government
official, I obtained my Ph.D. in physicaloceanography in 1999 from the Universityof Tokyo with my doctoral dissertation
entitled ‘Structure of the Kuroshio andMichida giving a lecture on oceanic current data management at the 7

I was a member of the CIC for almost all of the last 24 years, except from November 2007 to March 2010,
when I was a professor of the International Coastal Research Center, a branch research center of AORI locatedin Otsuchi Town, Iwate Prefecture. I was appointed as an Advisor to the Director of AORI from 2011–2015 andthen as a Vice Director from 2015–2019. I was also appointed as an Advisor to the President of the University ofTokyo for the 2011 academic year.
My research interests covered a wide range, including physical oceanography, as my baseline background,which mainly targeted the velocity structure and variability of oceanic currents in the surface mixed layer
by analyzing observational data measured with surface drifters and ADCP. Many other fields, such as
oceanographic data management and ocean policy, were extended research interests over the last 20 years.
While my research papers have mainly
been published in natural science journals,
some are social science journals, such as“Ecological Economics” and “Journal ofJapan Society for Ocean Policy” for example.
In addition, I have been involved in a seriesof research activities on marine microplastic
pollution since 2016.
While conducting the oceanographic
research and related studies above, roughly
one-third to a half of my efforts have beenspent on activities to promote international

then elected as the Chair of the IOC in 2023
at its 32 nd Assembly (see another article
in this issue). From 2015 to 2019, I was cochair of the International Oceanographic
Data and Information Exchange (IODE), a
flagship programme of the IOC with almost
60 years of history.
The CIC was established in 1994 topromote international cooperation in ocean
science. One of the primary goals of the
CIC was to lead IOC-related activities inJapan so that enhanced contributions fromJapan to the IOC could be realized. I wasin the Japan Coast Guard when the CIC

my retirement, I would like to remind
all faculty members of the AORI, as well as those of the CIC, that the IOC has played and will keep playing
essential roles in international coordination for ocean research, services, and marine policies, even though it isa small international organization in comparison to other ocean-related UN agencies. I do hope my successors
in the CIC and AORI maintain the promotion of IOC-related business and further enhance them under evencloser cooperation with the oceanographic community in Japan and with internationally leading institutes andorganizations worldwide. This might be a key component for my happy retirement.
Finally, I sincerely express my mosttremendous appreciation to all present
and previous members of t he CIC for
their continuous support, in particular, all
successive secretaries in my laboratory, Ms.
Masumi Arai, Ms. Chizuru Kinoshita, Ms.
Naomi Kobayashi, and Ms. Akiko Kasuya,
for their careful and precise administrative

professors, including Prof. Keisuke Taira,Prof. Makoto Terazaki, and Prof. Masaki
Kawabe, for encouraging and supporting
me in promoting international cooperation,
mainly through the IOC/UNESCO and its
subsidiary bodies.
Good luck to all, and may we all havea bright future in the ocean based on theName tags of international meetings attended by Michida between 1990s andspirit proposed by the IOC: ‘One Planet,2014. Michida has accumulated 100 more between then and 2024.

Visiting Professors’ report
LIU, Hongbin
Professor, Hong Kong University of Science andTechnology
I visited Professor Hiroaki SAITOʼs lab in the
Atmosphere and Ocean Research Institute (AORI), The
University of Tokyo, during December 2022 to January

122023. I have known Dr. Saito since 1999 when I was a
JSPS postdoctoral fellow in Nagoya University. We
have b e e n c ollab orating sinc e. I have always
considered AORI the best oceanographic research
institute in Asia and it is my great honour to have theopportunity to work with Dr. Saito and other globally
recognized scientists in this most prestigious research
institute.
During my visit to the Atmosphere and Ocean
Research Institute at the University of Tokyo, I had theopportunity to collaborate with Professor Hiroaki Saito
and his team on our shared interest in the role ofpicophytoplankton in the global carbon cycle. We
discussed the distribution of different ecotypes ofProchlorococcus and Synechococcus , the two mostimportant picocyanobacterial in the open ocean,

CIC NEWSLETTER No. 21 2023

affected by hydrographic features in the Pacific andIndian Oceans and their response to global warming.
We worked together on the data collected from theIndian Ocean by Dr. Siyu Jiang, a postdoc researcher
in Saito-sanʼs team. We also worked on the draft of apaper based on the results of that dataset.
As part of my visit, I gave a seminar on the effect ofnutrient limitation on phytoplankton thermal sensitivity.
It was an excellent opportunity to share my researchwith the team and receive valuable feedback fromthem. We also visited Professor Hiroyuki Ogataʼs lab in
Kyoto University, where I gave a seminar on thediversity and adaptation of Synechococcus in estuarine
waters, which was well-received by the audience.
Apart from academic activities, I enjoyed my stay in
Kashiwa and explored the vicinity of Tokyo. I hiked the
Tsukuba Mountain, visited the lakes of Fuji Mountain,
and tasted thewonderful food inTokyo and Kyoto. It
was a great culturalexperience, and I
appreciated thehospitalit y of theJapanese people.
Looking ahead, we plan to further collaborate on
the ecophysiology and molecular mechanisms of
picoplankton in the Pacific and Indian Ocean, with afocus on their role in carbon and nitrogen cycling. I am
excited about this collaboration and the potential
impact our research can have on our understanding of
the global carbon cycle.
In conclusion, my visit to Professor Hiroaki Saitoʼs
lab in the Atmosphere and Ocean Research Institute at
the University of Tokyo was a fruitful and enjoyable
experience. It was an excellent oppor tunit y tocollaborate with a renowned researcher in my field andhis team, share my research, and learn from theirexpertise. I am grateful for the opportunity and lookforward to futurecollaborations.

AORI visit August-September 2022
In August 2022, Andreas Fahlman visited Japan on ascholarship from AORI to work on two projects in ecophysiology with faculty at AORI. One project, let byDrs. Kagari Aoki and Katsufumi Sato, we measured theresting metabolic rate and hear t rate of small
cetaceans. The heart rate was measured with asuction cup attached physio-logging device developed
by Little Leonardo in Japan, and the respirometersystem developed specifically for smaller dolphins. The
respirometer system measured respiratory flow, andexhaled O2 and CO2, from which the energy consumed,

13

CIC NEWSLETTER No. 21 2023

animals manage O2 and CO2 while foraging for foodand makes it possible to understand limitations to
diving. Thus, these measurements provide us with amethod to predict how climate change may change theability for survival in cetaceans.
The project in turtles was led by Dr. Kentaro
Sakamoto and we worked with his students, and Drs.
Katsufumi Sato and Kagari Aoki in Oguchi to makemeasurements on heart rate and respiratory flow.
Recently, Dr. Sakamoto’s team has developed methods
to measure heart rate in free swimming turtles. This

uses the same heart rate logger as was used in thedolphins, but this is attached to the carapace of theturtles. As the heart rate is affected by respiration, we
wanted to see if we could use heart rate as a method
to estimate breathing frequency. If so, it may bepossible to determine breathing frequency in freeswimming tur tles. A s the breathing frequenc y
increases with metabolic demands, this would make itpossible to determine how activity and diving alters
metabolic cost.

Malcolm Roberts
Manager of global high resolution climate modellingat UK Met Office.

Visiting scientist at AORI, 2 Oct-26 Dec 2022.
This was my first visit to Japan for several years,
and my longest stay ever – I was one of the managersof the UK-Japan Climate Collaboration back in the early
2000s which involved many shorter visits to the Earth
Simulator in Sugita, and to Tokyo. During that time I
got to know many Japanese colleagues at JAMSTEC,CCSR and the University of Tokyo (as well as meeting
my wife Yoko!), and we’ ve ke pt in touc h andcollaborated since those times. So when my European
PRIMAVERA project finished in late 2019, we started
planning this visit – unfortunately we all know what
happened then! After many attempts we were finallyable to make the trip, very generously hosted by
Hasumi-sensei and greatly assisted by Kitajima-san.
Due to the delay in the trip, I had to split my timeand continue more Met Office work than was ideal.
This is because we have a new European project
EERIE starting in January 2023, for which I needed toprepare and start running a global coupled model withan 8km ocean resolution. Fixing various model
problems, and developing the required tools to docontinuous monitoring and assessment of such
simulations, took up some time. So far the model has
completed 120 years of pre-industrial spin-up, and I
plan to shortly include a 15km atmosphere resolution
and do the full CMIP6 simulations.
A key region of the real ocean is the Labrador Sea
in the North Atlantic, where ocean deep convection
occurs, and where we found problems in our previous
model simulations in CMIP6 HighResMIP. Discussions
with Hasumi-sensei and Kawasaki-san on the key

14

processes in this region highlighted the importance ofeddying and the representation of ocean bathymetry,
and further collaboration on this would be welcome in
EERIE, where we’ll have 4 different models at ~10km
global resolution in atmosphere and ocean.
As co-lead of HighResMIP (a new intercomparison in
C M I P 6 t o c o m p a r e g l o b a l m o d e l s a t ~2 5 k m
resolutions), we are now discussing how to progress
and improve towards CMIP7. I had ver y useful
discussions with Satoh-sensei on how HighResMIP canpotentially help to make links between global km-scalemodelling efforts such as NICAM and the DYAMOND
project, and longer term climate simulation at lower
resolutions. Satoh-sensei already had some ideas on a
1 year simulation designs for DYAMOND, and we’ll
discuss in HighResMIP if this could be incorporated
into our designs.
We also visited various other groups for in-person
discussions. At the Hokkaido University we had
productive talks with Minobe-sensei about the diurnal
cycle of precipitation, and using HighResMIP models tounderstand the causes of some recent tropical cycle
trends and possible future changes to bomb cyclones.
At JAMSTEC in Sugita we discussed ongoing work with

CIC NEWSLETTER No. 21 2023

MIROC and NICAM models, including work on thesynchronisation of the Kuroshio and Gulf Stream which
is very relevant. I also talked with Nonaka-sensei andNakamura-sensei and people involved in the HotSpot2
project about mid-latitude air-sea interaction processes
which will also be extremely relevant to EERIE. We
also visited MRI and had good discussions about
HighResMIP with Mizuta-san.
As well as our work, we managed to take some timeto enjoy Japan in autumn. We enjoyed the Shinkansen
on our way to Hokkaido, and visited many fish
markets, the Nikka whisky distillery, Toya-ko and thecoastline near Sapporo. We went to the fireworks

display at Tsuchiura, the Christmas market in Hibiya
Park, and the Railway Museum in Omiya, and I also
managed to climb Mount Tsukuba. It was also apleasure to meet Mike Fiorino and Johannes Iohmann
whom we shared an office with during our stay, andwe have some ideas for future collaboration with themas well.
Overall I enjoyed a wonderful time in Japan, andnow I’m back in the UK I’m missing the Tokyo sunshine
very much! Dōmo arigatō gozaimashita to everyone formaking me feel welcome at the University of Tokyo,
and I hope to return soon.

radiance contribution from aerosols.
In the above backdrop, the Cloud and AerosolImage r-2 (C A I-2) on-b oard G re e nhous e gas e s
Observing Satellite-2 (GOSAT-2) is a state-of-the-art
addition to the satellite based remote sensing ofaerosols. Even though most the satellite sensors
possess their unique strengths and weaknesses, CAI-2
on-board GOSAT-2 is expected to provide deeper
insight in to the several new aspects of global aerosol
characterization.
A key reason for my visit to the University of Tokyo
is to explore more about scientific utilization of CAI-2
data. To this end, I would like to extend my sincere
thanks to Prof. Ryoichi Imasu his heart-warming
welcome, wholehearted support, and attention to myvarious tasks at AORI. During my stay, I had very
fruitful scientific discussions with Prof. Imasu about
satellite retrieval of aerosols from different spaceborne sensors and assimilation of Black Carbon (BC)using numerical model simulations. As the lightabsorbing BC aerosols have very sensitive role inaffecting the Earth’s radiation budget and climate,satellite-based retrieval of BC from the CAI-2 on-board
the GOSAT-2, combining with surface measurements
over the Indian region is unique in terms of enabling
retrieval accuracy as well as expanding it to theunderstanding of global distribution of BC in near-realtime. A first level analysis in this regard is completed
during my stay at AORI.
Overall, my visit to the prestigious 1870s research
university has provided me with new insights into
various scientific information, academic environment
and the research and cultural arenas in Japan as awhole. It was a very smooth and successful experience

In current environmental research, atmosphericaerosol is a vital problem which plays important role inatmospheric optics, energetics, radiative transfer
studies, chemistry, climate, biology, and public health.
Because of their presence in the atmosphere, aerosols
influence the energy balance of the terrestrial
atmosphere, the hydrological cycle, atmospheric
dynamics, and monsoon circulations. However, thelarge uncertainties in the knowledge of accurate
aerosol type, their amount in the atmosphere andproperties are one of the central topics in current
climate and environmental research. While in situ
measurements provide accurate information about
aerosols’ chemical composition, size distribution andlocal variation, the scope of such observations for
wider geographical coverage and spatial variations ona regular basis is extremely limited. In this regard,
remote sensing measurements can provide a broader
view of the atmospheric aerosol field. Substantial
progress in the retrieval of aerosol properties fromsatellite measurements has been made in the past
three decades which has resulted in significant
improvements in the knowledge of aerosol
characterization and distribution over the oceanic
regions. However, over land, contribution of theradiance arising from reflection of solar radiation fromthe surface (which is bi-directional in nature) issignificantly large, and often far exceed the total

Makiko Hashimoto (Japanese Aerospace eXploration
Agency, JAXA) who provided insightful scientificperspectives on satellite retrieval of aerosols using
MWPM inversion algorithms. Thanks to Prof. Imasu fortaking me to JAXA. Furthermore, it was a pleasure to
visit the National Institute for Environmental Studies(NIES), Tsukuba, where I met Dr. Morino for scientificdiscussions, had a lab tour, and looked at the highresolution Fourier Transform Infrared Spectrometersystem. Visiting the greenhouse gas observatory at
the Center for Environmental Science in Saitama(CESS) is another fantastic experience to share with
Prof. Imasu. In addition to the above, I visited Kyoto
and met with Prof. Sochiko Hayashida and her team at
the Research Institute for Humanity and Nature(RIHN). I thoroughly enjoyed the scientific interactionthat followed my presentation.
During my stay in Japan, I also took part in a lot ofother activities and met many wonderful people. Firstof all, I want to express my thanks to Asako Ando-san
for the continuous support and help she has provided
me in various aspects. She helped me with everythingfrom sharing my international travel details to making
arrangements at Kashiwa International Lodge andgetting a bike to roam around. Additionally, it was apleasure to meet Anamika Anand-san, Arthur Ho Wang
LI-san, Ardhi Adhary Arbain-san, Yutaka Arai-san, Qiao
Wang-san, Yokifan-san. As a guide to new places,
shopping and foods in Japan, Anamika-san was always
helpful. Discovering live K ABUKI at the National
Theatre with Anamika-san is another delight. It was agreat opportunity to experience the essence of Kabuki,
which is listed as an intangible cultural heritage of

humanity. Similar to this, I had many more enjoyable
events beyond AORI, such as visiting parks, museums
and shrines in Tokyo and Kyoto. I am happy to notethat some temples in Japan combines the Japanese
double-roofed ‘irimoya ’ style and the Indian ‘tenjiku ’style in to one building.
Towards the end, I was also lucky to share theoffice with Dr. Mike Fiorino from USA. We had many
opportunities to discuss the scientific issues related toclimate change and to share our experiences at Japan.
Sharing the common room with friends from different
countries at the international lodge at Kashiwa was yet
another big enjoyment to have different varieties offood, as well as discussing about science, human life
and the future of earth. Itʼs also worth mentioning thebeautiful library on the Kashiwa Campus. Its ambience
was perfect for me to spend hours there and learn
about different disciplines through its rich content.
Thanks to the library staff for their quick action andsupport in arranging the visitor card within a day.
Every member of the institution shows unparalleledsincerity and dedication to their work. I am truly
impressed by the laboratory facilities and scientificresearch life in the UTokyo, Japan.
