A short technical explanation of CREMAP and the data employed are also included in an additional document.

The two zip files contain a) the GRID ASCII files of the monthly CREMAP ET estimates (mm) for the March-November period each year within 2000-2009; b) the WREVAP documentation with the original FORTRAN source code of Morton et al. (1985).

For additional information visit the State-wide ET Estimation page.
