LBA Regional Climate Data, 0.5-Degree Grid, 1960-1990 (Willmott and Webber)


This data set is a subset of a 0.5-degree gridded temperature and precipitation data set for South America (Willmott and Webber 1998). This subset was created for the study area of the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA), defined as 10° N to 25° S, 30° to 85° W. The data are in ASCII GRID format.

The data consist of the following:
