Summary

Actual ET (ETa) is produced using the operational Simplified Surface Energy Balance (SSEBop) model (Senay and others, 2013) for the period 2000 to present. The SSEBop setup is based on the Simplified Surface Energy Balance (SSEB) approach (Senay and others, 2007, 2011) with unique parameterization for operational applications. It combines ET fractions generated from remotely sensed MODIS thermal imagery, acquired every 8 days, with reference ET using a thermal index approach. The unique feature of the SSEBop parameterization is that it uses pre-defined, seasonally dynamic, boundary conditions that are unique to each pixel for the hot/dry and cold/wet reference points. This summary of the SSEBop ET dataset was created by attributing [...]

Purpose

This dataset was archived by the U.S. Geological Survey Center for Integrated Data Analytics here: http://cida.usgs.gov/thredds/ It was sampled to 12 digit hydrologic units using the Geo Data Portal. The results of the analysis were written to a NetCDF-CF Discrete Sampling Geometry file and are being served via the Sensor Observation Service protocol.

summaryThis dataset was generated using the USGS Geo Data Portal. A national coverage of Actual Evapotranspiration was aerially averaged for every HUC12 in the country. The NHDPlus Version 2 Watershed Boundary Dataset HUC12s were used for this subset.
