OpenET: A Transformative Tool for Tracking Water in the U.S. West

Openet is a satellite-based data resource supplying crucial water use information in 17 Western U.s. States.

Using the best available science to provide easily accessible satellite-based estimates of water use, OpenET is being used to improve U.S. water management. The data is available on 17 western states, most notably the area covered by the Colorado River basin.

The “ET” in OpenET stands for evapotranspiration, which is the process through which water leaves plants, soils, and other surfaces and returns to the atmosphere. It’s a measurement that farmers can use to estimate the amount of water being taken up or used by their fields and crops and that will usually need to be replaced through irrigation or rainfall.
