Climate grids are 30-year means of PET or PET-P calculated using the Thornthwaite method and PRISM climate grids. The Forsythe model was used in estimating average day lengths for each month.
The following images are for PET and PET-P in June, July, and August as an example. PET-Precipitation (PET-P) provides information on moisture deficit, where a positive value indicates moisture stress and a negative value indicates moisture surplus.
