Forcing and Normalizing Operation (FANO) method for the Operational Simplified Surface Energy Balance (SSEBop) ET model

We developed an improved approach to the parameterization of the Operational Simplified Surface Energy Balance (SSEBop) model using the Forcing and Normalizing Operation (FANO). The FANO parameterization was implemented on two computing platforms using Landsat and gridded meteorological datasets: 1) Google Earth Engine (GEE) and 2) Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA). Evaluation was conducted by comparing modeled actual evapotranspiration (ETa) estimates with AmeriFlux Eddy Covariance (EC) and water balance ETa from level-8 Hydrologic Unit Code sub-basins in the conterminous United States for five water-years (Oct-Sep; 2009, 2011, 2013, 2016, 2018). The results of the Water balance evaluation and other graphics to support the journal publication are available at "Results of the Water Balance evaluation and supplemental data for publication". The ET data set in raster format are available for download at "Annual Water-Year SSEBop Landsat 30-meter Actual Evapotranspiration (ETa) rasters for 5 years between 2009-2018 using the Forcing and Normalizing Operation".
