Cooling degree days base temperature

WebFor example, if the mean temperature was 75° F, then the GDD amount equals 10 for a TBASE of 65° F. You can think of Growing Degree Days as similar to Cooling Degree Days, only the base temperature can be something besides 65° F. In equation form: Where: TBASE = Growing Degree Day base temperature. TMEAN = mean … WebBy using a general climatological approach, the base temperature is set to a constant value of 24°C in the CDD calculation. If Tm ≥ 24°C Then [CDD = ∑iTim - 21°C)] Else [CDD = 0] where T im is the mean air temperature of day i. Examples: If the daily mean air temperature is 26°C, for that day the value of the CDD index is 5 (26°C-21°C).
