This research is focused on analyzing giant nuclei (GN) concentration (N<sub>GN</sub>) below RICO small cumulus clouds. It was found that these are substantially correlated with drizzle drop concentration (N<sub>d</sub)> at higher altitudes. The data used in this study was obtained from RICO experiment using the CCN spectrometer developed by Dr. Jim Hudson. The results obtained indicate that positive influence of GN on N<sub>d</sub> is greater than the negative influence of high critical supersaturation (S<sub>C</sub>) CCN on N<sub>d</sub> at high cloud altitudes where there are more drizzle drops.
