Greetings from Chief Scientist of GOSAT Science Teamby Gen Inoue, Professor, Research Institute for Humanity and Nature
Chief Scientist, GOSAT Science Team"IBUKI" is promoted by acooperative partnership among
Ministry of the Environment, Japan
Aerospace Exploration Agency, andNational Institute for Environmental
Studies. GOSAT Science Team isa group of scientists who gives
scientific advice to them. The central
figure of GOSAT Science Teamis Chief Scientist Dr. Gen Inoue.

"IBUKI" was successfully launchedlast year, and since then, it has been working
normally although there are minor troubles.
Various functional tests and data acquisition
have been carried out, and the quality ofthe obtained spectra exceeds the expectedlevel. We can say that hardware of "IBUKI" wassuccessful. The carbon dioxide concentrations
calculated from spectral data are consistent
with current knowledge as a whole when
there is no cloud or small amount of aerosol
within the field of view of the instrument.
It should be emphasized that "IBUKI" isobtaining data over the regions where there
were no ground or other measurements
before. So, I would like to conclude that "IBUKI
project is basically successful".
However, this only means the very basicpart of the whole objective of "IBUKI" hasbeen achieved, and we need to makemore efforts before IBUKI’s eventual goal;"Understanding of the global carbon dioxideand methane cycles."Large efforts must be paid to retrieve thecorrect concentrations even in the presenceof some, not much, amount of interferencessuch as cirrus cloud and aerosol. This isbecause the views without any interferences
are quite seldom. It will be achieved using all
the spectral bands as has been planned at the
beginning.
Especially, it is important to be able to1­­

retrieve the concentrations over large forests
even in the presence of scattered tiny clouds
because such clouds often develop due
to active evapotranspiration there. The
luck of the observation in large forest area,such as tropical forests in South America,
Africa or South-east Asia, and boreal forests
in Siberia or North America is serious. The
filling of the spatial observation gaps willcontribute significantly to the science of
global carbon dioxide and methane budgets.
Very important achievements on sources
and sinks, and atmospheric transport will be
expected if the quality of concentration datafrom "IBUKI" is high.
In the future, I think it will become more
important to investigate the emissions ofcarbon dioxide and methane not only inglobal scale but also in regional scale. If we
can utilize "IBUKI" data more to the studiesof emission inventories in the regions where
statistical data are not well managed, or
accidental emissions such as forest fires andleakages of natural gases, IBUKI will gain more
reputation. China, India and some countries
in South-East Asia and Eastern Europe alreadyshow interests in using "IBUKI"'s data for these
purposes. It also provides critical information
to decide the functions "IBUKI"’s follow-on
missions should have.

Research Section, CGER, NIES"IBUKI" obser ves the greenhouse gases in the ear th
atmosphere from space. To confirm the reliability of data is an
important task in the project.
On February 14, 20, and 23 of this year, NIES GOSAT Project
conducted an airborne observation as a part of the GOSAT data
products validation in cooperation with Japan Aerospace Exploration
Agency (JAXA), and measured the concentration of greenhouse gasesin the atmosphere around Tsukuba area using instruments on an
aircraft and a ground-based Fourier Transform Spectrometer (FTS).
The air at the altitude between 500m and 2000m was collected
over Tsukuba City, and between 2000m and 7000m was collected
over Kumagaya City where there is no flight regulation for that height.
The air was taken into the plane, and 16 flask samples were collected.
Onboard the aircraft was the Non-dispersive Infrared Analyzer whichuses infrared absorption of CO2 to measure the concentration of theCO2 continuously while the samples were being collected. During
the airborne observation, the direct solar radiation was measured
on the ground in the Atmospheric Minor Constituents Spectra
Observatory in the Climate Change Research Hall at NIES to obtainthe concentration of the greenhouse gas over Tsukuba. "IBUKI"’s FTS
observes the sunlight reflected by the surface of the earth as well as
the radiation from the land and sea surface and the atmosphere toestimate the concentration of the greenhouse gas in the atmosphere.
In this observatory at NIES, there is a similar FTS that retrieves theconcentration of the greenhouse gas in the atmosphere right above
Tsukuba by observing the direct sunlight. Additionally, sondes werelaunched from NIES to measure the weather conditions such astemperature, humidity, wind-direction and wind speed. There were tenother different observations carried out at once on February 20, 2010.
These results are going to be analyzed, and the data will be used for"IBUKI"’s data validation.
As you may already know, "IBUKI" is unable to observe thegreenhouse gas when there is a cloud. Fortunately, the observation on
February 20 was conducted in the warm and clear weather. NIES SeniorResearcher Isamu Morino was happy about the success of the airborne
observation; "It is almost clear sky today and now we have a set of data
under the observation condition with little chance of errors."

AHA! OF THE MONTH

Atmospheric Tracer Transport Model
Used in Inverse Modeling— Hiroshi Takagi
Specialist, CGER, NIES

The Level 2 data products of"IBUKI" show the spatial and temporalvariations of CO 2 on a global scale,but they are not direct indicators of
how much CO 2 was emitted throughhuman activities and how much thegas was taken up or released by theocean and forests. Regional emissions
and absorptions of CO 2 are inversely
estimated from the Level 2 data products
by using a computer program called"atmospheric transport model" that cansimulate the global movement of CO2
by the wind. This estimation method iscalled "inverse modeling."
The role of the atmosphericFigure: Flowchart of inverse modeling using "atmospheric tracer transport model" and "IBUKI"'s Level 2transport model in the inverse modelingdata products.
is to predict CO 2 concentrations along
the footprint of “IBUKI" ( ① in the figure) based on global meteorological data and modeled emission/absorption data ( ② ).
Although the transport model does quite well in predicting the concentrations, there are some differences between thepredicted and the Level 2 concentrations ( ③ ). These gaps, however, can be minimized by "tweaking" the modeled emission/
absorption data used to calculate the predicted concentrations as follows. In a region where the predicted concentration islower than the Level 2 value, the region’s CO2 emissions are increased (or the absorptions are decreased). In another region
where the predicted concentration is higher than the Level 2 value, the CO2 emissions are decreased (or the absorptions are
increased). This adjustment of the modeled emission/absorption data is carried out mathematically in the inverse modeling( ④ ). The outcomes, which are the modeled emission/absorption data adjusted to match the Level 2 CO2 concentrations, arethe emissions and absorptions estimated via the inverse modeling ( ⑤ ). The modeling research scientists in the NIES GOSAT
Project will estimate source/sink strengths in 64 global regions on a monthly basis, using the IBUKI’s Level 2 data products
combined with the ground-based observational data. The results will be released in 2011 as the Level 4 data product.

Starting this issue, GOSAT Project Office would like to bring you monthly updates on "IBUKI"’s standard data products available
to the public. This time, we would like to explain some basic facts, which are necessary for you to understand the upcoming articles of thisnewsletter.
The following six types of "IBUKI"’s standard data products are currently available to the public. The data are distributed in different units
noted in parenthesis.
1. FTS L1B (Scene: FTS data for one revolution are divided into 60 scenes, each of which normally includes more than 20 scans)
2. FTS L2 SWIR CO2 column amount (Scan: observation data of FTS, whose normal duration is four seconds)
3. FTS L2 SWIR CH4 column amount (Scan : same as above)
4. CAI L1B（Frame: CAI data for one revolution are divided into 60; but actually there are only 31-32 frames since the CAI data are acquired
only during the day time）
5. CAI L1B+ (Frame : same as above)
6. CAI cloud flag (Frame : same as above)"IBUKI"’s nominal operation started in
April, 2009, and Level 1 data products
