摘要：The global monitoring of the greenhouse gases is necessary to handle the global warming issue and the monitoring from space is very useful for the global monitoring. In order to realize this and repeatable monitoring, the GOSAT program was started. The mission of the GOSAT is to observe CO2 and CH4 column density with relative accuracy of 1 % for CO2 and 2 % for CH4 at 1,000 km square spatial scale and in 3 months average, and provides these data during the Kyoto Protocol's first commitment period which is from 2008 to 2012. It is expected to reduce sub-continental scale CO2 annual flux estimation errors by half using GOSAT. GOSAT has two main mission instruments to be called TANSO altogether. One of TANSO is the Fourier transform Spectrometer which observes CO2 and CH4 and another one is Cloud and Aerosol Imager whose data are used to compensate the FTS data.. In January of 2009, GOSAT was launched and the initial calibration was completed in July and the initial validation was started. In February, 2010, the initial validation was completed and the data release to the general users was started on Februay 18,2010. The data release to the PI, Princepal Investigator, had been performed prior to the data release to the general users. We are cooperating with NASA/J PL team on the calibration and validation and this collaboration has made notable achievement in the improvement of the analysis accuracy of the CO2 concentation
