Abstract

This paper presents preliminary results on dry deposition of ozone and submicronic aerosol particles using the eddy-correlation technique. In the absence of vegetal activity, and over dry soil (the site is located in Northern Spain near Zaragoza) with low resistance for ozone removal, ozone fluxes are controlled by dynamic and convective turbulence. The ozone deposition velocity has been normalized by a new velocity scale which is a combination of the friction velocity and the convective velocity. This reduced deposition velocity is a function of the dimensionless stability index (z/L). A similarity equation is proposed allowing the determination of deposition velocities in good agreement with the experimental data. Friction velocity and atmospheric
