Technical Abstract: Remote sensing data combined with land surface models can provide spatially distributed fluxes over large areas. However, capturing the full range of variability in the fluxes is dependent on the resolution of the remote sensing data. Clearly, for landscapes with patchy vegetation and dissected topography, the resolution is crucial for discriminating fluxes for the different land covers and for interpreting tower-based flux observations. In this paper, a high resolution Landsat 5 TM scene collected during the 2004 Soil Moisture Experiment (SMEX04) conducted in southern Arizona and Mexico was combined with local meteorological measurements in a land surface model at high (30 m) and low (960 m) resolution for investigating the impact of resolution on variability in land surface fluxes. This analysis will focus on a semiarid rangeland watershed, Walnut Gulch.
