Fig. 1: Statistical characterization of water vapor supersaturation in STP orographic clouds.

a Mean effective supersaturation (SSeff) and supersaturation calculated from the CCN spectrum (SSCCN) for each cloud case. b Mean and standard deviation of SSeff and SSCCN, along with the probability density functions (PDFs). c Correlation between case-averaged SSeff and SSCCN, with the black line representing the linear fit.
