Data CAL/VAL of FY-3/HY-2 MWRI with intercalibration of AQUA/AMSR-E

As a second generation of China's polar meteorological satellite, the satellites of FY-3A and FY-3B launched in 2008 and 2010, respectively, carried 11 sensors, including microwave sensors such as microwave temperature sounder (MWTS), microwave humidity sounder (MWHS) and microwave radiometer imager (MWRI) etc. To fuse the MWRI and AMSR-E data and promote MWRI applicability, brightness temperature (Tb) of multi-channel MWRI are first simulated based on a radiative transfer (RT) model, and the difference between the technical features of MWRI and AMSR-E for Tb observations, correspondingly, are analyzed. Data validation of MWRI and inter-comparison with AMSR-E data are discussed for monitoring drought, precipitation and flooding happened during the periods. It lays applicability of MWRI in future operational services.
