Suppression of chlorine activation on aviation-produced volatile particles
International audience We examine the effect of nanometer-sized aircraft-induced aqueous sulfuric acid (H 2 SO 4 /H 2 O) particles on atmospheric ozone as a function of temperature. Our calculations are based on a previously derived parameterization for the regional-scale perturbations of the sulfat...
