Map of gridded values of 1971-2000 avg precipitation minus avg PET.
Detailed Description
Figure 5. Map showing gridded values of 1971-2000 average precipitation minus average potential evapotranspiration (PET) (precipitation and PET estimates from McCabe and Wolock, 2011). The red line indicates zero, where average precipitation equals PET. PET exceeds average precipitation in brown areas, and precipitation exceeds PET in green areas.
