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.
