	The [[WRF Hindcast]] project generates the input data used by the [[Grow Degree Calculator]] (GDC) and the [[Soil Moisture Estimator]] (SME) applications. WRF stands for Weather, Research, and Forecasting and is a program made available by [http://www.wrf-model.org/index.php UCAR/NCAR] and other research participants. We use WRF to calculate a virtual weather station at a 3.3km resolution on an hourly basis for ~~about half of the Western United States~~.

	The [[Grow Degree Calculator]] project is based on the WRF Hindcast project and calculates the Grow Degree values for both crops and insects. Users can enter a location, a start and end date with lower and upper temps for the organism of interest. Output includes a text report, a plot of accumulated values over time, and an image the total accumulated values over the target sector.

The [[Soil Moisture Estimator]] project is also based on the WRF Hindcast project and estimates the soil moisture at a given location. This is a more sophisticated program than the GDC as it requires crop and soil information provided by the user.

			The standard reference evapotranspiration, ETo, is calculated on an hourly basis for a daily total. The ETo calculation is based on the Food and Agriculture Organization (FAO) method given in this [http://www.fao.org/docrep/X0490E/x0490e04.htm paper] and are not values calculated by the WRF model. The calculated ETo values and the WRF precipitation values give the atmospheric loads at the soil surface. These loads are presented to our implementation of the [http://www.nws.noaa.gov/oh/hrl/nwsrfs/users_manual/part2/_pdf/23sacsma.pdf Sacramento Soil Moisture Accounting] model for soil moisture estimation.
