Wieczorek, M.E., 2023, 30 Year (1990 - 2019) Annual Average Difference between Precipitation Potential Evapotranspiration: U.S. Geological Survey data release, https://doi.org/10.5066/P94THJVH/.

Summary

This metadata record describes the 30 year (1990-2019) annual average difference between precipitation potential evapotranspiration in millimeters in geotiff format. The source data is based on the ClimGrid netcdf data for precipitation and temperature (Wieczorek and others, 2022). Units are millimeters.

Purpose

Precipitation minus potential evapotranspiration describes the relationship between the atmosphere and the earth's surface. This effort was undertaken to estimate the 30 year (1990 - 2019) annual average difference between precipitation potential evapotranspiration (mm) from ClimGrid data. This component can be used to evaluate critical aspects of water budget issues such as potential impacts of climate variability on water supply for human and aquatic ecosystem needs.
