Abstract
Measurements are presented which show enhanced concentrations of cloud condensation nuclei, active at various supersaturations, downwind of wave clouds. Concurrent measurements of particle size spectra corroborate these measurements and suggest particle growth within the clouds. Modifications in the particle size spectra are most pronounced at diameters of approximately 1 micrometer. Measurements and modeling results suggest these observations can be explained by sulfate production in clouds.
