Dry deposition of gases to the land surface is an important sink for reactive trace gases in the troposphere. Understanding dry deposition is of importance for understanding air quality and its impacts on human health and vegetation. SURFEX calculates dry deposition using a software scheme that was recently developed in the SEEDS project (deliverable D3.4). The dry deposition software scheme calculates dry deposition velocities, which can be used as an input to calculate dry deposition fluxes in an air quality model. The dry deposition velocities are provided for ozone, sulphur dioxide, and reactive nitrogen compounds (NOx, ammonia, nitric acid, organic nitrates, and per-nitric acid). All of the dry deposition data are output on an hourly time resolution.
