Table 1. Summary of Land Surface Information Used in the CEMSYS Simulations Parameter Data Source Aerodynamic roughness Constant for bare soil, derived from vegetation height and LAI for vegetated surfaces [Raupach, 1994] Zero-displacement height Zero for bare soil, derived from vegetation height and LAI for vegetated surfaces [McVicar et al., 1996] Leaf Area Index Derived from SeaWiFS normalized difference vegetation index data Vegetation height Adapted from Australian Surveying and Land Information Group [1990] Soil particle-size distribution Particle-size analysis of selected soil samples Soil moisture Soil moisture model integrated into CEMSYS
