How are growing degree days calculated
WebWhat are growing degree days, and how are they calculated? Growing degree days (GDD), sometimes also called thermal days, are a unit of measure describing the amount of accumulated heat through the growing season. Temperature data from 1981 to 2010 was used to construct an interactive growing degree day map of the northeastern USA. WebCorn growing degree days (GDD) are calculated by subtracting the plant’s lower base or threshold temperature of 50 F (10 C) from the average daily air temperature in F or C. Average daily air temperature is calculated by averaging the daily maximum and minimum air temperatures measured in any 24-hour period.
