IEM :: ISUSM - Soil Temperature Probabilities

4 inch Soil Temperature Probabilities

This application computes soil temperature exceedance based on the observation record of a ISU Ag Climate site. The average daily 4 inch soil temperature is used in this calculation.

Spring: The values represent the percentage of years that a temperature below the given threshold was observed after a given date.
Fall: The values represent the percentage of years that a temperature below the given threshold was observed before a given date.

This application uses the legacy ISU Ag Climate network for its computations. Data from the newer ISU Soil Moisture Network is not considered.
