Report: The 1st International Workshop on GOSAT Data Utilization- NIES GOSAT Project Leader Tatsuya Yokota
First of all, I would like to convey our deepest condolences

to all the victims of the Great East Japan Earthquake. In the afternoon
of March 11, 2011, the National Institute for Environmental Studies,
the Japan Aerospace Exploration Agency, and the Ministry of
the Environment were hosting the 1st International Workshop
on GOSAT Data Utilization at the International Congress Center
EPOCHAL TSUKUBA in Japan. The workshop had to be closed dueto the earthquake that occurred halfway through the presentations.
I would like to express my sincere apology to those who traveled all
the way for this workshop.

Their instruments were set at the

the pulsed laser light. As such, the threegroups measured the vertical profile in

NEWSGlobal Oceanic Emission and Absorpton Maps of CO2 Gas Using
Model Simulations and Assimilation- Vinu Valsala, Research Associate,  and Shamil Maksyutov, Chief
  Biogeochemical Cycle Modeling and Analysis Research Section, CGER, NIES

Partial pressure of carbondioxide in equilibrium with thesurface ocean waters (pCO2) is a key parameter that determines

the absorptions and emissions of carbondioxide gas (CO2) by
the ocean. A positive (negative) difference of pCO2 between theatmosphere and ocean (i.e. ∆ pCO2) will cause an absorption(emission) of CO2 gas by the ocean. Therefore, a global map of

pCO2 is required to calculate the total oceanic absorptions andemissions of CO2 gas. The oceanic pCO2 values varies from region

to region depending on the surface ocean temperature andbiogeochemical *1 parameters.

We have developed an ocean model to calculate the surface

ocean pCO2. The model operations are based on ocean general

Principal Scientist

DR. TAROH
MATSUNOthe United States, but we did not have computers for that in Japan. We
also needed a specialized organization or research institute, but we did
not have that either. I thought I needed to make efforts to change thesituation.
In fact, back in the 1960s when the National Center for AtmosphericResearch (NCAR) was founded in the U.S., we Japanese meteorologists
were saying, "isn’t it nice to have an organization like that in Japan?" anduniversity faculties had a meeting to discuss the possibility of creating sucha facility.
Y: Is that true? When was this?
M: It was around 1963, and I participated in this effort. We drafted a plan
for an organization like a Japanese version of NCAR. The Kyoto University
submitted a budget request to the government in 1972, but it was neveraccepted for many reasons including the nation’s fiscal situation backthen. So, we had to give up the idea. Since I was involved in this activity,
I continued to think that we had to do something in Japan, remindingthat it is Japanese pioneers who were leading the world. In time, theperformance of Japanese computers became comparable with others in
the world in 1980s, so I thought I just had to found an organization.
At the same time, in 1970s and 80s I was involved in the research on ozone(O3) layer issues from early days because then I was studying dynamics
of the stratosphere. In 1972, I was already involved in the project toinvestigate effects of nitrogen oxide emissions from supersonic planeson the O3 layer, one of the first of O3 depletion issues. Since I was familiar
with this subject and I also knew Dr. Manabe’s work well, I began to thinkthat the ‘global warming’ would be a very big issue soon or later, and weshould have a research system ready to handle it by ourselves.
Y: At the NIES, I remember you were on the advisory board for the
Improved Limb Atmospheric Spectrometer (ILAS), a sensor for O3 layer
observation. Is this because you were studying the stratosphere?
M: Yes, I think that is possible. Before I was appointed to a professor in 1984,
I had been working in a rather theoretical studies on the fluid dynamics.
