GPM IMERG Final Precipitation L3 1 month 0.1 degree x 0.1 degree V07 (GPM_3IMERGM) at GES DISC

Version 07B is the current version of the IMERG data sets. Older versions will no longer be available and have been superseded by Version 07.The Integrated Multi-satellitE Retrievals for GPM (IMERG) is the unified U.S. algorithm that provides the multi-satellite precipitation product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 2021 version of the Goddard Profiling Algorithm (GPROF2021), then gridded, intercalibrated to the GPM Combined Ku Radar-Radiome...

07B版是IMERG数据集的当前正式版本，旧版数据集已不再提供，并已被07版完全取代。GPM集成多卫星反演产品（Integrated Multi-satellitE Retrievals for GPM，IMERG）是美国团队开发的统一算法，可为美国GPM团队提供多卫星降水反演产品。构成GPM星座的各类与降水相关的卫星被动微波（Passive Microwave，PMW）传感器所生成的降水估测值，将采用2021版戈达德廓线反演算法（Goddard Profiling Algorithm 2021，GPROF2021）进行计算，随后完成网格化处理，并与GPM联合Ku雷达-辐射计。
