Abstract :
The Advanced Microwave Scanning Radiometer for EOS (AMSR-E) was launched on May 4, 2002 aboard the NASA´s Earth Orbiting System (EOS) Aqua Satellite. This new instrument measures the Earth´s radiation in two orthogonally polarized channels at 6 frequencies extending from 6.925 to 89.0 GHz. Here we study the influence of surface radiation on retrieval of cloud liquid water (CLW) and precipitable water vapor (PWV) using multifrequency polarized measurements of AMSR-E. Based on this preliminary investigation, a physical method to simultaneously retrieve CLW and PWV is proposed to build.
