Soil Moisture and Agromet Models

Abstract

Two automated models, known as Soil Moisture and Agromet, used operationally to monitor crop growing conditions are described. The Soil Moisture model uses Thornthwaite's water balance method to estimate moisture parameters from daily temperature and precipitation analyses. The model is relatively simple, and it has been providing useful information for over 20 years. The newer and more complex Agromet model estimates daily evaporation potential using Penman's equation. This model also uses a complex cloud analysis to estimate radiation effects. Agromet provides daily grid-point analyses of temperature, precipitation, snow depth, radiation, and evaporation.
