Use of satellite data to improve parameterization of spatial and temporal variations of gaseous dry deposition in regional-scale models
The removal of gaseous substances from the atmosphere by dry deposition represents an important sink in the atmospheric budget for many trace gases. The surface removal rate, therefore, needs be described quantitatively in modeling atmospheric transport and chemistry with regional- and global-scale models. Because the uptake capability of a terrestrial surface is strongly influenced by the type and condition of its vegetation, the seasonal and spatial changes in vegetation should be described in considerable detail in large-scale models. The objective of the present study is to develop a model that links remote sensing data from satellites with the RADM dry deposition module to provide a parameterization of dry deposition over large scales with improved temporal and spatial coverage. This paper briefly discusses the modeling methods and initial results obtained by applying the improved dry deposition module to a tallgrass prairie, for which measurements of O{sub 3} dry deposition and simultaneously obtained satellite remote sensing data are available.
