Growing degree days (GDD) is a weather-based indicator for assessing crop development. It is a calculation used by crop producers that is a measure of heat accumulation used to predict plant and pest development rates such as the date that a crop reaches maturity. Nov 12, 2014 · One point of confusion for many people is that “degree days” sounds like a unit of time. It’s not. That’s why we can have 5 heating degree days in one day and well more than 365 degree days in a year. Atlanta, Georgia has about 3,000 heating degree days each year (65° F base temperature). It’s not a unit of time. So we need to calculate heating degree days (HDD) for each day. One day, that is Sunday, the outside temperature is 65 minus 49 the outside temperature will give you the degree days. Similarly, 65 minus 47° Fahrenheit, one day times 65 minus 51 in this case. One day times 65 minus 60 and one day 65 minus 65. This would be zero. One day 65 ... May 02, 2019 · Cooling Degree Day is a measure that helps to simplify the cost of projected energy consumption.
