[ACG38-P08] Implementation and Validation of Rainfall Normalization Module for GSMaP Microwave Imagers and Sounders
Keywords:Precipitation, Validation, Microwave radiometer, Inter-calibration
In order to validate the MMN, scatter diagrams, zonal mean evaluations, and some statistical indices of precipitation intensity are compared between before and after the MMN correction using match-up data within 15 minutes for each sensor with the Dual-frequency Precipitation Radar (DPR) and the Global Precipitation Measurement (GPM) Microwave Imager (GMI) onboard the GPM core observatory.
The zonal mean precipitation after the MMN correction was closer to the GMI than before the MMN correction. The distribution of monthly mean precipitation anomaly for each sensor relative to GMI was closer to that of GMI relative to DPR after the MMN correction. The distribution of the monthly mean precipitation anomaly for each sensor relative to the GMI was close to that of the GMI relative to the DPR after the MMN correction.
