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 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 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.
