Abstract
Dry deposition on natural surfaces is one of the major removal pathways for air pollutants. In order to develop mathematical descriptions for the numerical simulation of the transport, removal, and ecological impact of pollutant gases and aerosols, the dependence of dry deposition rates on physical, chemical, and biological parameters must be understood. Such relationships can be studied by using several experimental methods to determine the vertical fluxes of pollutants over natural surfaces. The possible experimental methods include aerodynamic, modified Bowen ratio, eddy correlation, variance, and eddy accumulation. The relative advantages and disadvantages of these methods are discussed, with consideration being given to the sensor response time and accuracy. The roles of atmospheric stability and the zero plane, site and instrumental requirements, and averaging time are discussed for flux measurements.
