Abstract

Microwave measurements strongly depend on the incidence angle of the incoming radiance. Although the SSM/I instruments are designed for constant incidence angle, small deviations caused by the satellite orbits exist. The effects of these incidence angle variations on brightness temperatures are investigated. As a consequence a correction procedure is developed and applied to measured brightness temperatures. Significant differences between corrected and uncorrected brightness temperatures and retrieved meteorological parameters are found, especially for the SSM/I on DMSP F10
