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.[1] It is a successor to the GCOM-W and the GOSAT-2 satellites. GOSAT-GW was jointly developed by the Japan Aerospace Exploration Agency (JAXA), Ministry of the Environment, and the National Institute for Environmental Studies (NIES). GOSAT-GW was launched on 28 June 2025, on the last launch of JAXA’s workhorse H-IIA rocket.[2]
Overview
[edit]GOSAT-GW is a Japanese Earth observation satellite that was successfully launched on 28 June 2025. Unlike its predecessor GCOM-W, GOSAT-GW will not be placed in the A-train satellite constellation orbit. The satellite has two remote sensing instruments: the Total Anthropogenic and Natural emissions mapping SpectrOmeter-3, known as TANSO-3, and the Advanced Microwave Scanning Radiometer 3, known as AMSR3. The mission of GOSAT-GW is to monitor greenhouse gas concentration across Earth's atmosphere and quantifying emissions by nations alongside locating and measuring significant emission sources.[3]
