The Global Change Observation Mission-Water (GCOM-W1)

Click image for alternate view

Status: Current
Mission Category: A-Train
Launch Date: May 18, 2012

Japan Aerospace Exploration Agency (JAXA) mission (No NASA contribution)

The “Global Change Observation Mission” (GCOM) aims to construct, use, and verify systems that enable continuous global-scale observations (for 10 to 15 years) of effective geophysical parameters for elucidating global climate change and water circulation mechanisms.

Water circulation changes will be observed by a microwave radiometer onboard the GCOM-W (Water) satellite (scheduled to be launched in Japan Fiscal Year 2012). The GCOM-W will observe precipitation, vapor amounts, wind velocity above the ocean, sea water temperatures, water levels on land areas and snow depths.
