This data set provides estimates of daily total precipitation from the European Center for Medium Range Weather Forecasts (ECMWF) ERA-40 Reanalysis (ECMWF 2002). Data cover the period 1 January 1979 to 31 August 2002. Data were obtained from the National Center for Atmospheric Research (NCAR) Data Support Section dataset ds117.0 (). Precipitation is archived as 6 hour accumulations of convective and large scale (Stratiform) precipitation. Daily total precipitation was computed by summing 6 hour accumulations of convective and large-scale components. Fields of total precipitation were regridded from the native N80 (roughly 1 degree resolution) reduced Gaussian grid to the Equal-Area Scalable Earth 25km Grid (EASE 25km grid) using a bilinear interpolation scheme. This scheme is described in ECMWF [2003]. The data is presented in 24 sub-datasets of different spatial and temporal aggregations.
