Investigation of Microphysical Assumptions in TRMM Radiometer's Rain Profile Algorithm Using KWAJEX Satellite, Aircraft & Surface Datasets

Abstract

The Tropical Rainfall Measuring Mission (TRMM) level 2 radiometer precipitation profile algorithm employs assumed (cloud model- derived) vertical microphysical structures and radiative transfer within the inversion process to generate rainrate estimates. To date, this algorithm has been evaluated through raingauge and ground radar intercomparisons, algorithm- to-algorithm intercomparisons, diagnostic moisture budget analyses, and physical hypothesis testing. None of these approaches has specifically addressed the underlying microphysical properties of the algorithm itself. Therefore, what remains is perhaps the most fundamental check -- direct intercomparison of the assumed profile microphysics with actual three- dimensional microphysical observations.
