摘要：The major sensor of the Water Series of Global Change Observation Mission (GCOM-W1) is The Advanced Microwave Scanning Radiometer-2 (AMSR2). AMSR2 is multi-frequency, total-power microwave radiometer system with dual polarization channels for all frequency bands. The instrument is a successor of AMSR on the Advanced Earth Observing Satellite-II (ADEOS-II) and AMSR for the Earth Observing System (AMSR-E) on NASA's Aqua satellite. Standard products of GCOM-W1 based on AMSR2 data are currently defined. All the eight standard products are: integrated water vapour, integrated cloud liquid water, sea surface temperature, sea surface wind speed, and sea ice concentration over ocean, snow depth and soil moisture content over land, and precipitation over the globe except for high latitude. Development of the GCOM-W1 system is going smoothly. Current target launch year of GCOM- W1 is in Japanese fiscal year 2011. Participation of GCOM-W1 in the A-Train constellation is now being coordinated. This is beneficial both to the inter-sensor calibration between AMSR-E and AMSR2, and synergistic use of the multiple instruments available in the A-Train. Offline simulation system of a land surface model has been developed at JAXA/EORC as for a pilot system of the future data assimilation products merging satellite data and model estimates, and shows promising results. The future possibility of installing a U.S. provided scatterometer on the second generation satellite of GCOM-W (GCOM-W2) is under discussion. Simultaneous active and passive microwave measurements will enhance the water cycle observation capability of the GCOM-W series
