Postscript version of this map	ASCII Grid version of Total Annual Precipitation Data

This map is a representation of total annual precipitation within South America. (Legates, D.R. and C. J. Willmott. 1990a. Mean Seasonal and Spatial Variability in Gauge-Corrected, Global Precipitation. Intl. J. of Climatolgy 10: 111-127.) This data set is in ASCIIGRID format and can be ingested into Arc/Info software with the ASCIIGRID command or into other geographic information system or cartographic software capable of ingesting a matrix of values to form a raster layer. This data is referenced to a geographic coordinate system and its units are in millimeters per year.
