Fig. 3: Aerosol-driven variations in cloud water as functions of fine aerosol (FA) or coarse sea spray aerosol (CSA) concentrations under a fixed cloud temperature depth (CTD) of 1–2 K.
From: Fine and coarse aerosols control of cloud water by evaporation-precipitation dynamics
The upper panels show (a) liquid water path (LWP) and b cloud fraction (Cf) as functions of FA concentrations under fixed CTD (1–2 K) and CSA (20–40 μg·m−3). The lower panels show LWP and Cf (c, d) as functions of CSA concentrations under fixed CTD (1–2 K) and FA (0.5–0.8 μg·m−3). Lines represent average LWP and Cf at 10 concentration bins for FA and CSA, corresponding to the 0–10%, 10–20%, …, and 90–100% quantiles. Line colors transition from blue to red, indicating increasing cloud-top humidity. N indicates the number of cases. For each line, a slope was calculated using linear regression to fit cloud property variations to aerosol variations across the aerosol bins. Vertical error bars represent standard errors.
