Abstract
Realistic air quality modeling requires accurate simulation of both meteorological and chemical processes within the planetary boundary layer (PBL). Therefore, accurate and consistent methods for simulation of both meteorological and chemical surface exchange processes are critical for realistic modeling of boundary layer atmospheric chemistry. In vegetated areas, the primary pathway for surface fluxes of moisture as well as many gaseous chemicals is through vegetative transpiration. Thus, in the course of the authors model development program, the authors are developing improved modeling techniques which will consistently simulate both meteorological and chemical surface fluxes. The authors have been developing a more advanced land surface and PBL model for mesoscale models as described by Pleim and Xiu (1995). The authors are also developing a dry deposition model which uses many of the same parameters computed in the evapotranspiration model.
