AB: A network of seven scintillometer transects was established in New Mexico in 2006 covering different soils, vegetation types, and altitudes. Scintillometers measure spatially-averaged sensible heat fluxes over transects of 0.5 - 4 kms, i.e., over footprints comparable in size to several pixels of a satellite image. The Surface Energy Balance for Land (SEBAL) algorithm is applied to radiances from Landsat and MODIS to obtain net radiation Rnet, soil heat flux G, and sensible heat flux H. The latent heat flux is obtained from the energy balance equation as LE = Rnet - G - H. The scintillometer measurements are used to validate and calibrate the SEBAL sensible heat flux product. Results from this ground-truthing experiment and plans for automated and calibrated daily evapotranspiration maps will be presented.
