The current tendency in 'physically based' soil-vegetation-atmosphere transfer (SVAT) schemes is to use increasingly complex process descriptions to predict evaporative fluxes at both patch and landscape scales. This approach does not take proper account of the heterogeneities that are evident in any landscape. A top-down approach to sub-grid-scale land surface parameterization would suggest that the current complexity may not be supported by the calibration data available.
