Question
If the mean daily temperature is 18 oC and the base temperature is 8 oC, what is the thermal time accumulated for that day?
Solution
The thermal time, also known as growing degree days (GDD), is a measure of heat accumulation used in phenology. It is calculated by subtracting the base temperature from the mean temperature of the day.
Here are the steps to calculate the thermal time:
Step 1: Identify the mean daily temperature. In this case, it is 18°C.
Step 2: Identify the base temperature. In this case, it is 8°C.
Step 3: Subtract the base temperature from the mean daily temperature.
So, the calculation would be:
18°C (mean temperature) - 8°C (base temperature) = 10°C
Therefore, the thermal time accumulated for that day is 10°C.
