USCRN Average vs Mean data

From the downloaded data from uscrn

        Average temperature, in degrees C, during the 24 hours of the day.
        Note: USCRN/USRCRN stations have multiple co-located temperature
        sensors that record independent measurements. This value is a single
        temperature that is calculated by averaging 24 full-hour averages
        derived from the multiple independent measurements of 5-minute intervals
        during each hour

        Mean temperature, in degrees C, calculated using the typical historical
        approach of (T_DAILY_MAX + T_DAILY_MIN) / 2.

 

Mean temperature gives twice the slope of average
