GPM SSMI on F11 (GPROF) Climate-based Radiometer Precipitation Profiling L3 1 day 0.25 degree x 0.25 degree V07 (GPM_3GPROFF11SSMI_DAY_CLIM) at GES DISC

Version 07 is the current version of the data set. Older versions will no longer be available and have been superseded by Version 07. The "CLIM" products differ from their "regular" counterparts (without the "CLIM" in the name) by the ancillary data they use. They are Climate-Reference products, which requires homogeneous ancillary data over the climate time series. Hence, the ECMWF-Interim (European Centre for Medium-Range Weather Forecasts, 2-3 months lag behind the regular production) reanalysis is used as ancillary data to derive surface and atmospheric conditions required by the GPROF algorithm for the "CLIM" output. The GPROF databases are also adjusted accordingly for these climate-referenced retrievals. 3GPROF products provide global gridded monthly/daily precipitation averages from multiple satellites that can be used for climate studies. The 3GPROF products are based on retrievals from high-quality microwave sensors, which are sensitive to liquid and ice-phase precipitation hydrometeors in the atmosphere.版本07为本数据集当前正式版本，旧版本已停止提供服务，且已被版本07完全替代。 "CLIM"类产品与常规同名产品（名称中不含"CLIM"后缀）的核心差异在于其所采用的辅助数据。此类产品属于气候参考产品 (Climate-Reference products)，要求气候时间序列中的辅助数据具备严格的均一性。因此，为生成"CLIM"类产品的输出，GPROF算法 (GPROF)所需的地表与大气条件将以ECMWF-Interim再分析资料作为辅助数据进行推导——该资料来自欧洲中期天气预报中心，其数据更新较常规生产滞后2-3个月。同时，针对此类气候参考反演结果，GPROF数据库也已完成相应调整。 3GPROF产品可提供多颗卫星反演得到的全球网格化月/日降水平均值，适用于气候研究相关工作。3GPROF产品基于高质量微波传感器的反演结果，此类传感器能够灵敏探测大气中的液态与冰相降水水凝物。
