The TRMM Multisatellite Precipitation Analysis (TMPA): Quasi-Global, Multiyear, Combined-Sensor Precipitation Estimates at Fine Scales

摘要: Abstract The Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA) provides a calibration-based sequential scheme for combining precipitation estimates from multiple satellites, as well gauge analyses where feasible, at fine scales (0.25° × 0.25° and 3 hourly). TMPA is available both after in real time, based on calibration by the TRMM Combined Instrument Microwave Imager products, respectively. Only after-real-time product incorporates data present. dataset covers latitude band 50°N–S period 1998 to delayed Early validation results are follows: reasonable performance monthly scales, although it shown have rate–dependent low bias due lack of sensitivity rates over ocean one input products [based Advanced Sounding Unit-B (AMSU-B)]. At finer successful approximately reproducing s...
