Surface fluxes and atmospheric stability obtained from a surface energy balance model with parameters estimated from satellite remote sensing
Surface fluxes and atmospheric stability affect atmospheric dispersion through their impact on low-level turbulence, mixing layer height, and mesoscale circulation patterns. In the first part of this paper, a sensitivity study is performed to demonstrate the impact of the land surface on energy fluxes and atmospheric stability. In the second part, a methodology to estimate surface heat fluxes and stability is presented. The method is based on the combined use of a surface energy balance model and satellite remote sensing of green vegetation cover and surface soil moisture, and requires either standard single-level meteorological data, or the use of a mesoscale meteorological model.
