CORRECTING WIND SCATTEROMETERS FOR RAIN

Scatterometers on spacecraft provide vector wind fields over the oceans. Those launched by the United States and Japan (Seasat, NSCAT, QuikSCAT, ADEOS-II) operate at Ku-band frequencies where backscatter from and attenuation through rain can corrupt the measurements. European systems (ERS-1/2, ASCAT) operating at C band are relatively unaffected by rain. For the Ku-band systems, one must somehow identify rain-corrupted data and either discard it o
