    • Integrated Multi-satellitE Retrievals for GPM (IMERG) CPEX V1

    Metadata Updated: March 13, 2026

    The Integrated Multi-satellitE Retrievals for GPM (IMERG) CPEX dataset includes measurements gathered by IMERG during the Convective Processes Experiment (CPEX) field campaign. IMERG combines precipitation estimates from multiple passive microwave (PMW) sensors available in a 30-minute analysis time. These estimates are retrieved using the Goddard Profiling (GPROF) algorithm that converts PMW brightness temperatures to a precipitation estimate. The CPEX field campaign took place in the North Atlantic-Gulf of America-Caribbean Sea region and conducted a total of sixteen DC-8 missions. The CPEX campaign collected data to help explain convective storm initiation, organization, growth, and dissipation in the North Atlantic-Gulf of America-Caribbean Oceanic region during the early summer of 2017. IMERG combines information from the GPM satellite constellation to estimate precipitation over the majority of the Earth's surface. Data are available from May 24, 2017 through July 16, 2017 in netCDF-3 format.
