Influence of the local urban environment on the thermo-radiative and hydrological behaviour of a garden lawn

Abstract Several urban canopy models now incorporate vegetation to represent local cooling related natural soils and plants evapotranspiration. Nevertheless, little is known about the realism of simulating these processes turbulent exchanges within canopy. Here, coupled modelling thermal hydrological was investigated for a lawn located in an environment, which soil temperature water content measurements were available. The ISBA-DF surface-vegetation-atmosphere transfer model inline TEB mixed environments. For present case study, applied first evaluated its default configuration. Particular attention then paid parameterization above lawn, description characteristics. results highlighted importance taking into account roughness surrounding obstacles computing over realistic surface temperatures. nature texture vertical heterogeneity are also key properties evolution exchanges.
