The AMSR3 microwave radiometer is installed on the GOSAT-GW satellite, also known as Ibuki GW.
Akihiro Kuze previously served as Project Manager of the Ibuki-2 (GOSAT-2) mission.
Japan launched Ibuki (GOSAT), the first satellite dedicated to observing greenhouse gases from space.
JAXA and ANA have applied observation techniques derived from JAXA’s greenhouse gas observation satellite Ibuki (GOSAT) starting in September 2020 to aircraft-based atmospheric measurements.
JAXA's Hiroshi Yamakawa shared updates on the GOSAT-GW satellite, HTV-X, and MMX Mars moon exploration project.
GOSAT-GW is equipped with the Advanced Microwave Scanning Radiometer (AMSR3).
The Japan Aerospace Exploration Agency (JAXA) launched the Greenhouse Gases and Water Cycle Observation Satellite (GOSAT-GW) in June 2025.
GOSAT-GW aids in tracking the water cycle and advances climate change studies.
The AMSR3 sensor onboard GOSAT-GW observes microwaves emitted from the land, sea surface, and atmosphere.
Mitsubishi Electric is the prime manufacturer for GOSAT-GW.
GOSAT-GW was launched on June 29 aboard the last unit of the domestic core rocket, H-IIA, which is the 50th unit.
The TANSO-3 sensor onboard GOSAT-GW was developed by a contract from MOE to JAXA and is a successor to TANSO-FTS-2, which was onboard GOSAT-2.
It has been revealed that the annual increase in CO2 concentration observed by GOSAT from 2023 to 2024 is the largest since observations began, at 3.5 ppm per year.
GOSAT-GW continues the water cycle variation observation mission of Shizuku (GCOM-W), launched in 2012, and the greenhouse gas observation missions of GOSAT, launched in 2009, and GOSAT-2, launched in 2018.
GOSAT-GW is part of the Earth observation satellite project GOSAT promoted in cooperation with JAXA, the National Institute for Environmental Studies (NIES), and the Ministry of the Environment (MOE).
The greenhouse gas and water circulation observation satellite, GOSAT-GW, has completed its initial function confirmation operation period and has begun routine operation.
ADRAS-J is designed to rendezvous with and characterize a Japanese H-2A upper stage rocket body left in low Earth orbit after the 2009 launch of the GOSAT Earth observation satellite.
The target upper stage is from an H-2A rocket that launched the GOSAT Earth observation satellite in 2009.
ADRAS-J is designed to rendezvous with and inspect an aged, derelict H‑2A upper stage left in low Earth orbit after the 2009 launch of the GOSAT Earth observation satellite.
Japan plans to extend its GOSAT series in 2024 with the GOSAT Greenhouse gases and Water cycle (GOSAT-GW) spacecraft that will carry an infrared spectrometer to measure monthly mean concentrations of greenhouse gases and calculate national anthropogenic greenhouse gas inventories.
