Hilly-land satellite pixel-scale aerodynamic surface temperatures (AdST) are investigated using LAS (Large Aperture Scintillometer) and meteorological observations during 21-22 May 2001,indicating that the calculated temperatures are predominantly subject to estimated roughness lengths and,to a less extent,to estimated Bowen ratios,with errors to within 3.0 K between the AdST calculations and hilly radiometric surface temperatures retrieved from satellite data with the split window model.The errors depend heavily on the model used and the zenith angles and azimuth of the satellite and sun with respect to the observational site.
