The Global Precipitation Measurement (GPM) Core Observatory launched on February 27, 2014. The GPM mission actually comprises an international network of satellites that provide the next-generation global observations of rain and snow. The two instruments on the Core Observatory, the Dual-frequency Precipitation Radar (DPR) and the GPM Microwave Imager (GMI), provide the baseline standard to maintain consistency among global precipitation retrieval and climate studies.
The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) archives and distributes GPM data products, which are processed and then provided to the DISC by the Precipitation Processing System (PPS), also located at NASA Goddard Space Flight Center. GPM Profiling Algorithm (GPROF) data, DPR data, and the Integrated Multi-satellitE Retrievals for GPM (IMERG) data are the primary data sets available, and can be acquired from the GES DISC using several different methods, which are listed below. Note that ftp access will be unavailable in the future when a User Registration System (URS) is implemented at the GES DISC.
Users can access GPROF Level-2 and Level-3 data through their Data Holdings Web Interface, which also contains documentation and services for each product. Users can also directly access the products through the following:
♦ Mirador search
♦ OPeNDAP (ftp://gpm1.gesdisc.eosdis.nasa.gov/ftp/data/opendap/)
Level-2 and Level-3 DPR data can be accessed from:
Users can access IMERG Half-hourly and Monthly products through their Data Holdings Web interfaces, which also provide documentation and services for each product. The data can also be directly accessed via the following methods:
Simple Subset Wizard
♦ IMERG data products
