Abstract
Predicting the cloud condensation nuclei (CCN) supersaturation spectrum from aerosol properties is a fairly straightforward
matter, as long as those properties are simple. During the Indian Ocean Experiment we measured CCN spectra, size-resolved
aerosol chemical composition, and aerosol number distributions and attempted to reconcile them using a modified form of Köhler
theory. We obtained general agreement between our measured and modeled CCN spectra. However, the agreement was not as good
during a time period when organic carbon comprised a quarter of the total mass of the aerosol in the submicron size range.
The modeled concentrations overpredict those actually measured during that time period. This suggests that some component,
presumably organic material, can inhibit the uptake of water by the electrolytic fraction of the mass.
