CPC Merged Analysis of Precipitation (CMAP)

Precipitation from five kinds of satellite estimates and the NCEP/NCAR reanalysis model output are combined for global coverage monthly precipitation values. The standard products merge only the 5 kinds of satellite estimates (GPI, OPI, SSM/I scattering, SSM/I emission and MSU). The enhanced products merge the satellite estimates with the blended NCEP/NCAR Reanalysis precipitation. Both products are available as monthly totals, pentads and long term monthly means on a global 2.5 degree latitude-longitude grid. All data is in the netCDF format.
