The use of airborne and space observations to map surface heat fluxes and soil water content at heterogeneous land surfaces was studied. Algorithms to estimate evaporation fluxes with satellite observations were evaluated against measurements. Spatialcorrelation lengths were studied with estimated maps of latent heat flux. Soil water content was estimated with microwaves; effects of soil mineral composition and solute concentration were studied in the laboratory. The significance of observed spatial variability was evaluated with probability distribution functions of errors of estimated latent heat flux and soil water content. Roughness properties were studied with laser measurements. Spatial fields of heat fluxes were obtained from a meteorologicalmodel.
