| Abstract |
Accurate modeling and prediction of global monthly precipitation have been extremely difficult because precise climatological data on the worldwide distribution of precipitation do not exist. The goal of the Global Precipitation Climatology Project (GPCP) is to provide global data sets of area, time-averaged precipitation for a minimum period of 10 years (1986-1995). To produce these data sets, GPCP will merge geostationary and polar-orbiting satellite microwave and infrared data with rain gauge data from more than 6,000 stations. GPCP data will be used to validate atmospheric general circulation and climate models, and to study the hydrologic cycle.
