Level 3 Soil moisture (AMSR2) productEntry ID: GCOM-W1_Level3_AMSR2_SM
Abstract: The Advanced Microwave Scanning Radiometer 2 (AMSR2) onboard the GCOM-W1 satellite is a remote sensing instrument for measuring weak microwave emission from the surface and the atmosphere of the Earth. From about 700 km above the Earth, AMSR2 will provide us highly accurate measurements of the intensity of microwave emission and scattering.
The antenna of AMSR2 rotates once per 1.5 seconds and ... obtains data over a 1450 km swath. This conical scan mechanism enables AMSR2 to acquire a set of daytime and nighttime data with more than 99% coverage of the Earth every 2 days.
Definition of Level3 data processing
* Grid data with 0.1/0.25 degrees (10/25km) resolution
* Brightness temperatures and geophysical parameters
