1. Introduction
The Fourth Assessment Report issued by the Intergovernmental Panel on Climate Change (IPCC) in2007 states that most of the observed increase in global average temperatures since themid-20th century is very likely due to the observed increase in anthropogenic Green
House Gas (GHG) concentrations. The drastic increase in the concentration of GHGs,
particularly carbon dioxide (CO2), caused directly and indirectly by human activities, is attributed to
the fact that the emission of CO2 into the atmosphere in the process of the mass consumption offossil fuel, deforestation, etc., significantly surpasses the absorption by the land ecosystem and theoceans. Thus, it is imperative to balance the emission due to human activities and the absorption by
the nature, in order to stabilize the climate for the future. In the meantime, however, we, humans,
have not grasped, to a sufficient level, the mechanisms of the absorption by land ecosystem andocean, and the climatological feedback in the carbon cycle involving atmosphere, land ecosystemand ocean. This lack of understanding comprises a substantial part of the uncertainty in predicting
future climate change.
The clarification of these problems involves not only an ascertainment of the spatial and temporalvariations in the CO2 emission from human activities but also a calculation of the spatial distribution
and temporal variation of CO2 and also methane (CH4), which is the second largest contributor to
global warming after CO2, and the spatial distribution and temporal variation of the source and sinkin land ecosystem and oceans, based on earth observation, and ultimately an attainment of adequate
scientific knowledge on the underlying mechanisms. These efforts to observe GHG concentrations
and to analyze the causes of their variations at some locations are, though still limited, in progress.
On top of these attempts, it is vital to observe the distributions of CO2, CH4, and other GHG
concentrations, which fluctuate both spatially and temporally, on the global scale, using satellite
platforms, in a continuous and systematic manner, and to elucidate the current issues, with a goal toelevate the reliability of prediction of future climate change and climate system models effective forassessing the consequences of climate change.
Under such circumstances, the GOSAT (Greenhouse gases Observing SATellite) Project was
initiated and has been promoted jointly by the Japan Aerospace Exploration Agency (JAXA), theNational Institute for Environmental Studies (NIES) and the Ministry of the Environment (MOE)(hereinafter referred to as the “Three Parties” collectively). The mission of the Project is to increase
the accuracy of the flux (source and sink) estimation of the GHGs on the sub-continental basis (afew thousand kilometers square), thereby to contribute to environmental administration efforts suchas ascertainment of fluxes per region and evaluation of the carbon balance in forests. The Projectwill further contribute, through research on applications of the data acquired by GOSAT, to an
accumulation of scientific knowledge regarding the global distribution of GHG concentrations andits temporal variations as well as the global carbon cycle mechanism and its impact on climatechange, which will assist the prediction of climate change and evaluation of consequences therefrom.
At the same time, the Project aims to maintain and further evolve conventional earth-observing
technologies to develop new methodologies to measure GHGs and enable engineering development
necessary for future earth-observing satellites.
To achieve these goals, JAXA takes charge of developing and launching the satellite with the sensors
on board, calibrating and operating the sensors, acquiring observation data, and processing the1acquired data to Level 1 (spectral) products, whereas NIES undertakes the examination ofrequirements for the sensor specifications, development and operation of the higher-level productprocessing system, development of the data processing algorithms, generation of Level 2 (GHG
concentrations), Level 3 & 4 (global distribution of GHG concentrations, and distribution of carbon
source/sink based on them, etc) products, validation of data quality, and storage and provision of thegenerated data products. Furthermore, the MOE supplements the development of the sensors andbears the responsibility for utilization of the GOSAT data in its environmental administration
through the acquisition of validation data and scientific use of mission data. The Three Parties havebeen and will continue to be vigorously carrying forward the research and development necessary
for fulfilling these tasks with the help and advice from the GOSAT Science Team, which wasestablished and is administered by the Three Parties.
The Research Announcement to be made herein (hereinafter referred to as the “RA”) solicits
proposals for research on the data processing algorithms, calibration, validation, carbon balance
estimation/atmospheric transport models, and scientific use with respect to the GOSAT data from thepublic, on top of the basic research and development topics to be performed by the Three Parties,
with an aim to make the outcomes of the Project more effective. All research teams responding tothis RA whose proposals are selected by the Three Parties based on the results of evaluation by the
RA Selection and Evaluation Committee (hereinafter referred to as the “Committee”) will be granted
a priority in data distribution, the right to make observation requests (within a predetermined scope),
accommodation in obtaining other related data, and so forth. Incidentally, the Committee will consistof the members selected and requested by the Three Parties from among Japanese and non-Japaneseexperts and specialists.
The succeeding chapters in this document describe the contents of the GOSAT Project in detail,including items ranging from the equipment onboard the satellite, overview of data processing
algorithms, calibration and validation plans to data utilization plans. Applicants to this RA are
encouraged to read the contents of this document carefully and make active efforts to write research
proposals.

22. Definitions of the GOSAT/TANSO Research Announcement (RA)
2.1 GOSAT Project
GOSAT carries an observing instrument called Thermal And Near-infrared Sensor for carbon
Observation (TANSO). The GOSAT/TANSO is composed of two sensors called Fourier Transform
Spectrometer (FTS), which measures greenhouse gases (GHGs), and Cloud and Aerosol Imager(CAI), which collects information on cloud and aerosol.
The primary purpose of GOSAT is to measure the global distribution of GHG concentrations and its
temporal variation and to increase the accuracy of the flux estimation of GHGs on the
sub-continental scale, thereby contributing to the sustention and development of systemized
observation in accordance with the Kyoto Protocol, while at the same time facilitating theenvironmental administration efforts, including ascertainment of the flux per region and evaluationof the carbon balance in forests during the first period (2008-2012) as specified by the Protocol. In
the meantime, the Project is intended to develop GHGs-measurement technologies and othertechnologies necessary for future earth-observing satellites, by standing on and further evolving theexisting earth-observing technologies.
2.2 Purpose
The purpose of the RA is to open to public an opportunity for researching on the data processing
algorithms, calibration, validation, carbon balance estimation/atmospheric transport models, andscientific use of the GOSAT data, in addition to the basic research and development topics to be
performed by the Three Parties, with a goal to make more use of the outcomes from the Project. The
research topics selected by the Committee and adopted by the Three Parties will be subject topreferential data distribution, the right to make observation requests (of reasonable amount), andaccommodations in obtaining other related data, etc.
The implementation of the RA is expected to bring about additional researches by other parties than
JAXA and NIES, which will supplement the research to be conducted in accordance with thecalibration and validation plans of the Project, facilitation of studies on the processing algorithms,
carbon balance estimation/atmospheric transport models, and utilization of the GOSAT/TANSO data,
objective evaluation of the research concerning the effectiveness and usefulness of the data,
expansion of opportunities for researchers and scientists inside and outside Japan to access the
GOSAT data, and so on.
2.3 Scope
The GOSAT/TANSO RA is open to all countries across the world, not limited to Japan. All
individual researchers, educational organizations, research institutes, and governmental bodies who
are willing to use the GOSAT data for non-profit and peaceful purposes are entitled to participate in
the RA. In this manner, private companies are also qualified for submitting research proposals aslong as their themes are for non-profit and peaceful purposes.
Investigators involved in carrying out the research themes selected in the RA are called “RA3

Investigators” for the purpose of the RA. A team of RA Investigators working on a research theme
will elect one principal investigator (hereinafter referred to as “PI”) who will represent the team.
The PI will act as the contact person with the Three Parties in carrying out the research on theselected theme, such as communication, data transfer, submission of necessary documents, etc. In
principle the research organization (hereinafter referred to as “RO”) to which the PI belongs shallalso be responsible for signing the joint research contract with the Three Parties, as provided inAppendix E hereto, when selected for the RA. The signer may be the PI himself/herself only in caseif the PI does not belong to any organization.
Incidentally, the research teams selected for the RA may be requested to conclude a separate contract
in order to strengthen the cooperative relationship between the team and the Three Parties.
2.4 Basic Policies
The GOSAT/TANSO RA will be conducted based on the following policies:
1) The Three Parties will establish a committee to select the research proposals and to follow theirresults. This committee will be referred to as “the Committee” hereinafter. Research proposals
submitted in response to the RA will be evaluated by the Committee, and they will be selected by
the Three Parties based on the evaluation results by the Committee. The Committee shall be
responsible for not only evaluating the submitted proposals but also, as shown in Chapter 8.2.1
hereof, evaluating the progress and adequacy of the adopted researches.
2) The research period shall be the operational period of GOSAT/TANSO plus the operational periodof its ground system — five years after the launch, in principle (until January 22, 2014) —. Any
long-term research to be conducted, which goes beyond one year, will be subject to interim
reporting to the Three Parties, basically once a year.
3) The GOSAT/TANSO RA took place in April to July 2008 for the first time and in April to June2009 for the second time, whereas the third RA, this time, is in action from August to October2010. Next RA opportunities will be determined based on the status of applications to these threeRAs.
4) PI of a research team may make multiple research proposals on different themes during themission period. (In other words, a single person may submit proposals on more than one research
themes to be carried out under this RA scheme.)
5) The PI may submit observational requests to the extent determined by the Committee per research
theme.
6) The PI may request for distribution of GOSAT data free of charge to the extent designated by theCommittee per research theme.
7) Applications for the GOSAT/TANSO RA and research plans shall be submitted via the Websites
run by the RA Office or by e-mail, in principle; those documents sent by conventional mail orother means may also be accepted according to the situation.
8) Research themes to be conducted under the RA scheme were selected in August 2008 for the first
RA and in July and August 2009 for the second RA. The third RA selection will be evaluated in
January 2011. Likewise, in the future, the selection will be administered at each time the RA ismade.
9) Proposal titles and names of PIs and their ROs will be disclosed on the Websites run by the RA
Office when their research themes are selected for the RA.
10) Outcomes of the GOSAT/TANSO RA must, in general, be disclosed to the public in the form of4

papers published on academic journals and other media and at the same time be reported at the
research result reporting meetings held by the Three Parties.
11) The Three Parties do not provide any financial assistance to PIs, in principle, under the RA
scheme.
12) RO (or PI in case if he/she does not belong to any organization) must conclude the joint
research contract, as provided in Appendix E, with the Three Parties prior to the start of research
activities on the selected research theme.
2.5 Implementing Organization of the GOSAT/TANSO RA
The Three Parties have set up an office in charge of the RA within the NIES GOSAT Project office,for firm and efficient implementation of the GOSAT/TANSO RA. The RA Office carries out thefollowing tasks in accordance with the basic policies set forth by the Three Parties.
1) Prepares the RA procedures and release them to the world.
2) Carries out administrative works as the secretariat of the Committee.
3) Accepts proposals submitted in response to the RA and requests the Committee for due evaluation
for selecting research themes.
4) Notifies the selection results to all PIs who submitted research proposals and assists those selected
PIs in signing the joint research contract (see Appendix E) necessary for carrying out the
research.
5) Receives the outputs of the research from the PIs by the deadline designated in the contract anddistributes them among the Three Parties.
6) Assists in organizing the research result report meetings to be held by the Three Parties.
7) Notifies the completion of the joint research agreement to the RO (or the PI in case if he/she does

12. Expected Research Topics
The Three Parties have been and will be continually promoting the GOSAT Project by playing therespective roles in the research and development deemed as necessary for achieving its purpose withthe advice and help from the GOSAT Science Team. The specific research and development
activities within the Project include; the calibration of the GOSAT/TANSO equipment, validation ofhigher-level products (observation and analysis for validation), development and improvement of thedata processing algorithms, development of atmospheric transport models and land ecosystemmodels, generation of source inventories, and development of carbon flux estimation models, etc.
Also, the analysis methods for such basic phenomena that have influence on evaluation of thecharacteristics and quality of data such as temporal variation of concentrations and carbon balance
distributions are studied. Furthermore, with the GOSAT Project, research on advanced application of
the GOSAT/TANSO data, for example, detection of CH 4 leakage from natural gas pipelines or local
forest fires, and so forth, is conducted. More details are provided in the succeeding section.
Through the implementation of the RA, the GOSAT Project expects to benefit from the RA researchoutcomes for developing higher level data products. At the same time, the Project wants to see theresearch field of data application being further facilitated, and the data acquired by the GOSAT willcontribute to resolve the global-warming issues through the effective utilization. Therefore, the
GOSAT Project is open and willing to accept new research proposals from all parts of the world.
In this Chapter hereunder is provided a summary of research topics to be or to have been carried out
in the GOSAT Project. It is anticipated that a large number of research themes, that will supplement
the research topics of the GOSAT Project, that will utilize the applicant’s own validation data, or thatare based on very original and unprecedented perspectives, will be proposed.
12.1 Research Topics conducted or targeted by the GOSAT Project1) Calibration
The calibration-related research topics conducted or targeted by the GOSAT Project include
calibration (including wavelength calibration) when interferogram is transformed into spectra,
calibration in relation to correction of the variation of the observation sensors’ field of view,
instrument function calibration, radiance calibration, etc. as for TANSO-FTS, and radiometriccalibration, geometric correction, calibration of the sensor sensitivity, etc. as for TANSO-CAI.
2) Data processing algorithms
The processing algorithm-related research topics conducted or targeted by the Project include
development of fast data processing algorithms, sunglint observation data processing methods,
processing algorithms using polarized data, and algorithms to extract parameters fromthermal-infrared data, evaluation of spectral parameters of gaseous molecules and sunlight
spectra, combined use of short wavelength infrared and thermal infrared data, etc.
3) Carbon flux estimation, atmospheric transport models
The model-development-related research topics conducted or targeted by the Project include
development and refining of source inventory databases, refining of atmospheric transport andland ecosystem models, etc., development of carbon flux estimation models with hightemporal/spatial resolution, etc.
4) Validation20

*Before the launch
