An Intercomparison of Techniques to Determine the Area

This relationship was used to map the latent heat flux on a pixel-by-pixel basis, resulting in <λE> = 194 W m-2. The third method makes use of a supervised classification of the thematic mapper image into eight land use classes. An average latent heat flux was assigned to each class by using field measurements of the latent heat flux.
