A Model for Dry Deposition Calculations

FIGURE 19.4 Correlations of particle deposition velocities measured in wind tunnel for c = 1 m (Sehmel, 1980). 

We present in this section a dry deposition model for calculations of both gas and particle dry deposition. The deposition velocity for gases is based on (19.2), 

The aerodynamic resistance for both gases and particles is given by (19.14). The quasi-laminar resistances for gases and particles are

The bulk canopy stomatal resistance is calculated from tabulated values of rj, the solar radiation (G in W m ), and surface air temperature (T, in °C between 0 and 40°C) using
