Validation Of Simulated MM5-Coupled Promet Land Surface Temperature Using MSG/SEVIRI Data
Abstract
Progress in land surface process modelling has improved both spatial and temporal resolution and process representation. A crucial variable in land surface mass exchange and energy balance is land surface temperature (LST), as it controls latent and sensible heat flux. Aim of this work was to validate diurnal cycles of LST of the MM5-coupled land- surface-atmosphere process model PROMET with time series of spatial LST derived from MSG/SEVIRI. The evaluation of diurnal cycles revealed that the model is capable of modelling LST for the whole study region with a coefficient of determination up to 0.99. Our results furthermore indicate that land use type, date and time of day are in close relation to differences between modelled and retrieved LST, whereas land use variability exerted a relatively minor influence. The study illustrates both the potential of current land- surface-atmosphere models to describe dynamics of LST as well as the validation potential of MSG/SEVIRI.
