Comparison of three schemes for predicting surface sensible heat flux

This paper compares three schemes which use standard meteorological observations to estimate values of the surface sensible heat flux. All three schemes have been designed to be applicable to mid-latitude, grass covered surfaces. The estimates are compared with heat flux data measured by a sonic anemometer situated at Cardington in the UK. Consideration is also given to the problem of predicting the surface sensible heat flux when could information is not available, as is the case for automatic weather stations. Provided incoming solar radiation is available, the predictions are not substantially worse.
