GOSAT (Greenhouse gases Observing Satellite) is a JAXA (Japan Aerospace Exploration Agency) mission within the GCOM (Global Change Observation Mission) programme of Japan. The GOSAT mission goals call for the study of the transport mechanisms of greenhouse gases such as carbon dioxide (CO2) and methane (CH4).
The emphasis is on atmospheric monitoring to clarify the sources and sinks of CO2 on a sub-continental scale.
The overall mission objective is to contribute to environmental administration by estimating the Green House Gases (GHGs) source and sink on a sub-continental scale and to support the Kyoto protocol that was adsorbed at COP3/UNFCCC (3rd session of the conference in the framework of climate change) in 1997. The protocol calls for a reduction of greenhouse gases, in particular CO2; it requires all parties to reduce their emissions by 5% below the level of the year 1990, for the period of 2008-2012

Since 24 November 2018, the GOSAT satellite observations have been temporarily suspended by JAXA due to an unexpected issue causing the satellite enter ‘low load mode'.
29 November 2018
Due to maintenance at Jaxa the dissemination of GOSAT data products on the ESA server will be suspended between 28 November 2018, 01:00(UTC) - 02 December 2018.
