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.
