Uncertainty Analysis on Quantities Predicted by the Hydro- Thermodynamic Soil Vegetation Scheme (HTSVS)

This paper discusses an uncertainty analysis preformed on a soil vegetation atmosphere transfer scheme described in Kramm et al. (1996). The effects of using several uncertain but required parameters in the prediction equations were estimated using Gaussian Error Propagation. The analysis considered the effects on the model prediction with respect to certain soil and atmospheric conditions that were varied over typical value ranges. It is shown that the effects of the uncertainty in the parameters on the predicted quantities can vary strongly. However these effects change only slightly with respect to different soil and atmospheric conditions. 1
