The Advanced Microwave Scanning Radiometer 3 (AMSR3), launched in June 2025 aboard the Global Observing SATellite for Greenhouse gases and Water cycle (GOSAT-GW), is a remote sensing instrument designed to measure weak microwave emissions from the Earth’s surface and atmosphere. AMSR3 is characterized by its very wide range of observation channels and is equipped with a G-band antenna subsystem (G-AS) in addition to the conventional AMSR series, enabling the measurement of snowfall and upper-level water vapor. Furthermore, a 10.25 GHz channel has been added to improve the resolution of sea surface temperatures (SST). This paper presents an introduction to the hardware configuration of AMSR3 and reports on the evaluation of its observation performance in orbit.
