AbstractA simple method for calculating the surface area density of aerosol particles starting from lidar backscattering ratios is described in this work. Surface density is the key parameter to be included in model assessments of the ozone perturbation following the eruption of Mt. Pinatubo. As an example we have used a photochemical 2D model to calculate the sensitivity of O3 depletion to the surface density of volcanic aerosols. Monthly averaged profiles of ozone concentration measured with a DIAL system for ten months after the eruption are also shown.
