英文摘要	Comparisons of high-resolution extended range CCN spectra measured at 100 m altitude with cloud and drizzle microphysics in the Rain in Cumulus over the Ocean (RICO) aircraft field project are presented. CCN concentrations, NCCN, active at supersaturations, S, >0.1% showed positive relationships with cloud droplet concentrations, Nc, measured at intermediate (606–976 m) and very high altitudes (1,763–3,699 m). These correlation coefficients, R, progressively increased with S while the two-tailed probabilities, P2, progressively decreased with S to < 10−6 at 1.6%S. More important were the positive relationships between NCCN active at S < 0.1% and drizzle drop concentrations, Nd, at high (977–1,662 m), very high and high-very high altitudes combined (977–3,699 m). All of these relationships were consistent for eight different cloud liquid water content, Lc, thresholds (for Nc) and Lc bins (for Nd) ranging from 0.0002 to 0.3 g/m3. Negative relationships between CCN modality and low altitude (76–475 m) cloudiness coupled with no relationship of NCCN active at any S with Nc of these low clouds indicated a cloud effect on ambient aerosol. This is a demonstration of clouds causing bimodal aerosol. © 2021. The Authors.
