Abstract
Abstract Eddy-correlation measurements of small particle deposition fluxes were made during the STARS ∗ campaign in the Sahelian area of Niger, in November 1989. The measurements showed a significant evolution of deposition velocity throughout the day, strongly influenced both by the atmospheric stability and a high friction velocity with values from 30 to 60 cm s − . Values of the deposition velocity I d , greater than 0.5 cm s −1 were found around 0100, while measurements made in neutral and stable conditions led to values lower than 0.1 cm s −1 . These results were partly confirmed by those obtained by the variance technique. A parameterization for aerosol deposition velocity derived in terms of friction velocity and the Monin-Obukhov stability length scale L , was found to be in agreement with past results obtained by the same techniques.
