Evaporative Stress Index

The Evaporative Stress Index (ESI) shows higher and lower than normal evapotranspiration rates from the land surface, corresponding to areas of higher and lower water use.  ESI uses data from the GOES satellites to produce 10km resolution data for the CONUS.  ESI is a USDA project in cooperation with NDMC and NOAA.
