The energy received by the earth through insolation is lost by outgoing radiation.

Atmosphere is mainly heated by outgoing radiation from 2 to 4 pm. So the maximum temperature is recorded between 2 and 4 pm regularly and minimum temperature is recorded around 4 am before sunrise.
- Mean Temperature:
-
The average of the maximum and minimum temperatures within 24 hours is called mean daily temperature [(87°F + 73°F)/2=80°F].
-
Diurnal range of temperature is the difference between the maximum and minimum temperatures of a day. Annual range of temperature is the difference between the highest and lowest mean monthly temperatures of a year.
