MWRI - Feng-Yun - 3 - Regional Data Service
Description
The EARS-MWRI service collects data from the Micro-Wave Radiation Imager (MWRI) instrument, on board the FY-3D spacecraft, operated by CMA.
MWRI is a conical scanning microwave imager at five frequency points with dual polarizations (10 channels); The sensor measures thermal microwave emission of land and ocean surfaces, and measures various forms of water in the atmosphere, clouds, and surfaces.
The MWRI imager can penetrate clouds, providing an all-weather measurement capability. The spatial resolutions are from 12 to 80 km, depending on the wavelengths. At higher-frequency channels, such as 89 GHz, the scattering signature from the cloud and precipitation are also good indicators for detecting rainfall over land and ocean.
