AB: Soil moisture data, measured as a volumetric content fraction, produced by multi-year runs of the Noah Land Surface Model were compared with soil moisture point measurements available from the Soil Climate Analysis Network (SCAN). The comparison area covered the Lower Mississippi Delta region. All Noah model runs were configured and performed using the NASA Land Information System (LIS) software. Noah retrospective runs were performed at horizontal grids with different spatial resolutions (ranging from 1km to 25km) to examine a scale-dependence accuracy/quality of simulated soil moisture fields. The North American Land Data Assimilation System (NLDAS) atmospheric forcing data were used in these simulations. The sensitivity of soil moisture fields to uncertainties associated with the specification of atmospheric forcing and soil parameters within the Noah model will be estimated and discussed.
