Summary
Abstract: The Tropical Rainfall Measuring Mission (TRMM) is a joint U.S.-Japan satellite mission to monitor tropical and subtropical precipitation and to estimate its associated latent heating.

The primary objective of the 2A21 is to compute the path integrated attenuation (PIA), using the surface reference technique (SRT). The SRT relies on the assumption ... View entire text
