Projet mondial d'établissement d'une climatologie des précipitations

OBS: The Global Precipitation Climatology Project (GPCP) is an element of the Global Energy and Water Cycle Experiment (GEWEX) of the World Climate Research Program (WCRP). It was established by the WCRP in 1986 with the initial goal of providing monthly mean precipitation data on a 2.5 x 2.5 degree latitude-longitude grid for the period 1986-1995. This was recently extended to the year 2000. The GPCP will accomplish this by merging infrared and microwave satellite estimates of precipitation with rain gauge data from more than 30,000 stations.
