Abstract:
Stochastic weather generators are often employed with process-based soil erosion prediction models.
Longterm observed weather station statistics (precipitation, temperature, etc.) can be used to provide a daily series of
temperature, precipitation, solar radiation, and wind parameters needed by an erosion model in its calculations
for evapotranspiration, plant growth, soil frost and thaw development, snow melt, infiltration, runoff, and soil
erosion. The Water Erosion Prediction Project (WEPP) erosion model typically uses the CLIGEN weather
generator to provide the daily climatic inputs that drive its hydrologic and erosion processes. This presentation
describes recently identified problems with CLIGEN and its weather station database, as well as enhancements
to improve the generator program and supporting database.
