"IBUKI" (GOSAT: Greenhouse gases Observing SATellite) is a greenhouse gas observation technology satellite jointly developed by the Ministry of the Environment, the National Institute for Environmental Studies (NIES), and the Japan Aerospace Exploration Agency (JAXA). It observes, from space, the concentration distribution of greenhouse gases such as carbon dioxide CO2 and methane gas CH4, which cause global warming. It was launched by the H-IIA Launch Vehicle No. 15 from the Tanegashima Space Center on January 23, 2009.
"IBUKI" has two sensors, both of which are provided for greenhouse gas measurement. Greenhouse gas concentrations have also been observed on the ground, but the number of observation points was only 348 (as of January 2013). "IBUKI" can measure the concentration distribution of greenhouse gases at regular intervals over almost the entire surface of the earth once every three days. The number of observation points has increased dramatically, and the quality of the data for discussing global warming has been improved.
The data can be used by anyone who registers, not just government agencies and scientists in each country.

"IBUKI 2" (GOSAT-2), a successor of GOSAT-1, was successfully launched on October 29, 2018. GOSAT-1 is steadily operating even after the originally planned five-year steady-state observation period, nevertheless troubles such as the failure of the refrigerator. Whereas conventional artificial satellites were designed to prevent breakdowns, GOSAT-1 is designed to be "safe even if it breaks down", such as by duplicating important parts.
GOSAT-1 has still been accumulating observation data of the column average concentrations* of carbon dioxide (CO2) and methane (CH4), which are the main greenhouse gases, in the clear sky region on a daily basis. We are analyzing the data received from the GOSAT-1.

* Column average concentration: Located in a vertical column from the ground surface to the upper end of the atmosphere. An average concentration that indicates the ratio of the target gas amount to the total amount of dry air.
