 and its temperature above a reference temperature. In many cases the reference temperature is inferred from common knowledge, i.e. "room temperature".

To make the meaning more explicit, it is the heat given to a body, when the body is in such a state that the heat gained by it doesn't convert to latent heat, or the energy supplied is not used up to change the state of the system (as in latent heat).

In the atmosphere
Earth's atmosphere

The Earth's atmosphere is a layer of gases surrounding the planet Earth that is retained by the Earth's gravity. Dry air contains roughly 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% Carbon dioxide in the Earth's atmosphere, and trace amounts of other gases....
