Evapotranspiration Units for Tule Valley and part of Sevier Valley, Utah

This data set represents evapotranspiration (ET) units based on a 2017-2018 summer mean modified soil adjusted vegetation index (MSAVI). The MSAVI information was used to partition Tule Valley and part of Sevier Valley, UT into six discharging ET units (playa; open water; very sparse desert shrub; sparse-to-dense desert shrub; grassland; and dense meadow and marshland), and scale estimates of groundwater evapotranspiration (ETg) to the basin level. ET units represent generalized groupings of vegetation and soil conditions. The units are constrained by a groundwater discharge area (GDA) which represents the area where discharge from evaporation by open water or bare soil and transpiration from phreatophytic plants exceeds the volume [...]
