Relevance of geographic information systems of landscape characteristics for hydroclimatological models

Research output: Contribution to journalArticlepeer-review

Abstract

An analysis with the Fourier Amplitude Sensitivity Test (FAST) and a sophisticated scheme of land surface processes for hydroclimatological models indicated that plant stomatal conductance and land surface roughness are the two landscape characteristics of greatest importance, in densely vegetated surfaces, for hydroclimatological models. In bare and sparsely vegetated surface, soil surface wetness, instead of stomatal conductance, becomes the predominant characteristic. The relation between these landscape characteristics and land surface energy fluxes is strongly nonlinear. -from Author
