HETEROGENEOUS PRODUCTION OF CLOUD CONDENSATION NUCLEI IN THE MARINE ATMOSPHERE

Model calculations are presented which indicate that newly created particles in the marine atmosphere will commonly only be able to achieve sizes, by means of gas‐phase processes, sufficient to activate in cumuliform clouds. Aqueous sulfate production in such clouds will be generally necessary to grow them large enough to activate in marine stratus clouds. Copyright 1990 by the American Geophysical Union.
