GCOM W1

NSSDCA/COSPAR ID: 2012-025A

Description

GCOM-W1 (Global Change Observation Mission-Water), a Japanese satellite, was launched from Tanegashima on 17 May 2012 at 16:39 UT by an H-2A rocket. The JAXA satellite, nicknamed Shizuku, which in Japanese means water drop, weighed 1.99 tonnes. It’s the first satellite for the GCOM-W series which will study water circulation systems in the Earth’s atmosphere. The GCOM-W1 will track precipitation, clouds, atmospheric water vapor, sea surface temperatures, sea ice, snow cover, and soil moisture. GCOM-W1 carries The Advanced Microwave Scanning Radiometer 2 (AMSR2), a remote sensing instrument for measuring weak microwave emission from the surface and the atmosphere of the Earth. It is expected to operate in orbit for at least five years.
