Hydrological Parameters Derived from Aqua AMSR-E Measurements

Atmospheric and surface parameters including sea surface temperature (SST), sea surface wind speed (SSW), cloud liquid and rain water, and total precipitable water (TPW) are derived from the Advanced Microwave Scanning Radiometer AMSR-E measurements. The AMSR-E brightness temperatures at 6.925 and 10.65 GHz are used to simultaneously retrieve SST, SSW, transmittance, upwelling and downwelling radiative comments. In addition, an emission-based algorithm is modified to retrieve cloud, rain water, TPW from the AMSR-E measurements at 10.65, 23.8 and 37 GHz. The derived products are being validated against various in-situ measurements from ocean buoy, radiosondes and dropsonds. The retrieval errors will be quantified as the project progresses.
