Resistance Model To Calculate Ozone Dry Deposition Velocity

Abstract

In July 1995, measurements of ozone concentrations, meteorological and surface parameters were carried out in a flat terrain over grassland in the northwest of Spain. Turbulent parameters, sensible and latent heat fluxes have been calculated using gradient technique. Fluxes and ozone deposition velocity and resistances were evaluated. The daily average value of dry deposition velocity was influenced by the wind velocity and the atmospheric stability. Resistances have been calculated according to a resistance model. 1 Introduction Dry deposition is the process where gases and aerosols are deposited directly
