The Soil Moisture Estimator couples the FAO prescribed method for calculating hourly standard reference evapotranspiration with the Sacramento Soil Moisture Accounting model. Climate data is derived from the Weather Research and Forecasting program calculated on an hourly basis at 3.3km, 10km and 30km resolutions and reported as accumulated daily values. Re-analyzed forcing files are used in a "hindcast" manner and the rendered images show these atmospheric surface loads at the 3 resolutions over the given time period. Use the mouse to hover over the images with a mouse to get pixel values. Valid input dates are from 2017-01-01 through the present minus a day.

To execute a run reflecting your local conditions, you can create and input your own crop, soil, irrigation and rain input files. The values in your files will be used, not the default values. To use your own files see SME wiki, Create 'csv' files for formatting instructions on each of the input files.
