EOSAP
Definition
- The EOSAP includes both empirical and modeling studies of rainfall and runoff from sample hillslopes to the entire Amazon basin. The data are contained in one file which is in tar and compressed format covering the period from January 1972 through December 1992. When this file is uncompressed and untarred, 21 HDF files are generated. Each HDF file corresponds to one year within the data set and contains 12 images (one image per month). The monthly total precipitation is in a 129 by 171 element array. The data is based on monthly rain datasets from Peru and Bolivia and daily rain datasets from Brazil. The precipitation data is derived from a linear interpolation of all stations within one degree with data from a minimum of four stations. Topographic and other information is not used in the interpolations. The precipitation data is in units of total mm/month. The extent of the gridded data ranges from latitudes of 20.2S to 5.6N and longitudes from 79.8W to 45.6W. The data are extrapolated to the edge of the grid but are deemed reliable only over the Amazon River Basin area.
