Solar Calc: Estimating Hourly Incoming Solar Radiation from Limited Meteorological Data
Soil Temperature and Moisture Model
The STM2 model predicts the soil temperature and moisture conditions based on very limited user inputs.
SeedChaser - Version 2.0
SeedChaser is a 1-D empirical vertical soil tillage distribution model with 1 cm grid spacing that predicts vertical redistribution of weed seeds following user selected (a) sequences of tillage implements, and (b) initial seed distribution values. Results of this model are particularly suited for weed seed emergence modeling. However, the model can be adapted easily to any surface broadcasted agrochemical or incorporated residues.
Nitrogen Decision Aid
The Nitrogen Decision Aid is a computerized program that predicts the amount of N mineralized from planting to side-dress or 5-leaf growth-stage. By applying just enough N-fertilizer to reach the critical soil nitrate concentration it is possible reduce this waste. This model is designed for Northern climates that will have some frost in the soil during the winter.
Global TempSIM - Version 1.0
The purpose of this tool is to estimate daily maximum and minimum air temperatures for a yearly cycle at any location on the globe.
Global RainSIM - Version 1.0
The purpose of this tool is to estimate daily precipitation patterns for a yearly cycle at any location on the globe. The user input is simply the latitude and longitude of the selected location.
Modified Langmuir Equation Spreadsheet
Spreadsheet from the paper entitled: Revisiting a Statistical Shortcoming when Fitting the Langmuir Model to Sorption Data by C.H. Bolster, Journal of Environmental Quality, 2008, 37:1986-1992. Spreadsheet has been modified to make a correction to the calculation of E for weighted data. (3/18/2010).
West Texas Mesonet Agro-Climate Monitor
West Texas Mesonet Agro-Climate Monitor shows the precipitation, temperature, weather forecast for mesonet stations in West Texas.
The Ogallala Agro-Climate Tool
The Ogallala Agro-Climate Tool is a Visual Basic application that estimates irrigation demand and crop water use over the Ogallala Aquifer region.
