Abstract

The heat exchange during dry conditions in Curlew Valley for selected clear days is determined from recordings in 10 minute intervals. The two heat budget components, radiative exchange and heat flow in the soil, are studied in detail.

Maximum surface temperature due to radiative exchange above, assuming no heat loss by other components, is determined.

Reduction of surface temperature by heat conduction into the ground was calculated as a second step to solve the heat budget equation.

Substantial heat flow throughout a day is restricted to the upper 10 cm of the soil. Diffusivity of the soil was determined from soil temperature using phase and amplitude equations, of which the first gave better results.
