CPC Merged Analysis of Precipitation

Precipitation Data, which is an average of the estimates from 5 different satellite sources: (GPI, OPI, SSM/I scattering, SSM/I emission and MSU). The raw data has missing values, however there is an enhanced version, blended with the NCEP/NCAR Reanalysis Precipitation values that supplement the missing values.

Spatial Coverage:

88.75N to 88.75S and 0E to 357.5 E based on a 2.5° by 2.5° grid

Temporal Coverage:

January 1 1979 through December 2001 for precipitation
