GSMaP V8

GSMaP has multi-satellite global precipitation map under the Global Precipitation Measurement (GPM) Mission, by using Dual-frequency Precipitation Radar (DPR) onboard GPM core satellites, other GPM constellation satellites, and Geostationary satellites. GSMaP provides hourly precipitation estimates. A gauge-corrected precipitation estimate is also provided.
Note: Both datasets may contain negative values, which denotes missing in observation data or no retrieval was done in microwave retrieval algorithm. More information can be found in the related documentation https://sharaku.eorc.jaxa.jp/GSMaP/document/new/DataFormatDescription_NRT8.pdf.

**Prendre note que pour les données horaires, la précipitation avec le timestamp à hZ consiste en la précipitation accumulée [h,h+1[.**

IMERG

Multi-satellite precipitation product for the U.S. GPM team. The precipitation estimates from the various precipitation-relevant satellite passive microwave (PMW) sensors comprising the GPM constellation are computed using the 2017 version of the Goddard Profiling Algorithm (GPROF2017), then gridded, intercalibrated to the GPM Combined Ku Radar-Radiometer Algorithm (CORRA) product, and merged into half-hourly 0.1°x0.1° (roughly 10x10 km) fields. The data contain multiple fields that provide information on the input data, selected intermediate fields, and estimation quality. In general, the complete calibrated precipitation, precipitationCal, is the data field of choice for most users. This is the "Final", satellite-gauge product, using both forward and backward morphing and including monthly gauge analyses.
