Abstract

By its end of mission in 2015, the Tropical Rainfall Measuring Mission (TRMM) far exceeded its three-year design life, providing over 17 years of invaluable Earth observations. This paper details how a previously undiscovered source of calibration error for the TRMM Microwave Imager (TMI) has been recently detected and how a simple mitigation technique may be applied for correcting bogus data. The source of error is believed to be Radio Frequency Interference (RFI) from geostationary satellites transmitters that are collected by the TMI Cold Sky Reflector antenna beams as they sweep through the equatorial plane. This paper details how this source of error was discovered, its characteristics, and how to flag and correct for the upcoming TMI 1B11 Archive/Legacy Data.
