Global Observing Satellite for Greenhouse gases and Water cycle

Global Observing Satellite for Greenhouse gases and Water cycle (GOSAT-GW), also called Ibuki GW, is a Japanese Earth observation satellite for observing the global water cycle and greenhouse gas monitoring. It is a successor to the GCOM-W and the GOSAT-2 satellites, and it is the third satellite in the GOSAT series. GOSAT-GW was jointly developed by the Japan Aerospace Exploration Agency (JAXA), Ministry of the Environment, and the National Institute for Environmental Studies (NIES). Operated by JAXA, the mission focuses on monitoring the average global concentrations of greenhouse gases, confirming greenhouse gas emissions inventories, and locating large sources of GHGs (greenhouse gases). The satellite is also being used to monitor the global water cycle. The system operates using two onboard instruments: AMSR3 and TANSO-3. These instruments utilize electromagnetic radiation to collect data. GOSAT-GW was launched on 28 June 2025 on JAXA's workhorse H-IIA rocket.
