Abstract :
The effects of rain on SeaWinds data are investigated using one year of SeaWinds /spl sigma//sub 0/ data, SSM/I and TMI rain rates collocated within 5 minutes of the SeaWinds observation, and tri-linearly interpolated ECMWF 10-m wind analyses. Attenuation and volumetric backscattering are parameterized in terms of rain rate, and the modification of the surface radar cross-section by rain roughening is found. The effects of different rain drop size distributions and non-uniform beamfilling are investigated.
