Global Precipitation Climatology Project (GPCP) - Pentad, Version 2.2

GPCP-Pentad

The Global Precipitation Climatology Project (GPCP) comprises a total of 27 products. The Version 2.2 Pentad product covers the period January 1979 to the present, with a delay of two to three months for data reception and processing. Version 2.2 supersedes all previous versions of the GPCP pentad product (Previous versions are not available from the NOAA/NCEI archive). All the GPCP products are produced by optimally merging precipitation estimates computed from microwave, infrared, sounder data observed by the international constellation of precipitation-related satellites, and precipitation gauge analyses, taking advantage of the strengths of each data type. Files are provided monthly, and the newest pentad data are appended to a yearly data file as they are available. Data are available on a 2.5 degree grid. Code and documentation are also available.
