Press the "Apply" button in the app below for a demonstration run. See our SME wiki for detailed instructions on how to use this application for your location and other information.
Note: currently about 1/2 of the western United States is available for processing. See the image at the bottom of this page.
Available sectors for processing are shown in shaded areas. For more information see the 'Sectors' section in our WRF Hindcast wiki page.
Agrineer.org thanks the following open source software providers. Their code made many of the screen graphic elements of our application much easier to accomplish: OpenSeadragon, OpenSeadragonImagingHelper, Knockout, Flot, D3.
The Soil Moisture Estimator couples the
prescribed method for calculating hourly standard reference
evapotranspiration with the
Sacramento Soil Moisture Accounting
Climate data is derived from the Weather Research and Forecasting program calculated on an hourly basis at 3.3km resolution. Re-analyzed forcing files are used in a "hindcast" manner.
Numerical calculations use the modeled 3.3km ETo and precipitation data. The images show these atmospheric surface loads at 3.3km, 10km and 30km resolutions per pixel. Hover over the images with a mouse to get pixel values.
