Filling the Biggest Data Gap in Water Management
How it Works
OpenET relies entirely on publicly available data as inputs to multiple well-established ET models to calculate ET. The primary inputs include data from Landsat, Sentinel-2, GOES, and other satellites; weather station networks and models; and field boundary and crop type datasets. The satellite data from Landsat are one of the most important inputs to the ET models, which use the satellite data to measure patterns in land surface temperature and vegetation extent and condition at the scale of individual fields. A complete description of the methods used by OpenET can be found here.
