Technical Abstract: Various remote sensing and in situ data have been collected over the Upper San Pedro Basin of southeast Arizona and northeast Sonora, Mexico, as part of the SALSA(Semi-Arid Land-Surface-Atmosphere) program. A common goal of these measurements is an improved diagnosis of the surface fluxes in semi-arid lands. In this session there are discussions of the broad coverage provided by remote sensing. This presentation focuses on the potential ability of an atmospheric model to aid in diagnosing the spatial distribution of surface fluxes over the entire basin. The model would ideally assimilate all kinds of remotely sensed data with different error characteristics and various temporal and spatial coverages. As a start in this direction, the RAMS mesoscale atmospheric model was run in a diagnostic mode in near real-time for all of 1997 at a 4 x 4 kilometer grid spacing over the entire San Pedro Basin.
