Methods for estimating the dry deposition velocities of atmospheric gases in the United States and surrounding areas have been improved. The improvements have been incorporated into a revised module of computer coding for use in numerical models of atmospheric transport and deposition of pollutants over regional scales. The dry deposition module computes deposition velocities for five seasonal categories and 11 land use types specified in a land use map. The key improvement is the computation of bulk surface resistances according to three distinct pathways of mass transfer. This has been accomplished successfully for H2O2, HCHO, acetaldehyde, methyl hydroperoxide, peroxyacetic acid, HCOOH, NH3, PAN, and HNO2, in addition to the original species (SO2, O3, NOx, and HNO3). Other factors considered include surface temperature, stomatal response to environmental parameters, the wetting of the surface by dew or rain, and the covering of surfaces by snow. Surface emission of gases and variations of the uptake characteristics by individual plant species are not explicitly considered.
