Abstract

Dry deposition velocity of submicronic aerosol particles has been measured during 3 campaings corresponding to different ground cover. The eddy correlation method cannot be computed blindly, because of low frequency fluctuations. After a proper filtration the dry deposition velocity can be obtained and parametrized. During unstable situations, dry deposition velocity exhibit high values. 1 Introduction Aerosol particles are removed from the atmosphere by dry and wet deposition. The knowledge of these phenomena is necessary to calculate the aerosol residence time in the troposphere, to modelize the transport at different scales, to determine the possible impact of aggressive aerosol particles on the biosphere, etc. We ha
