Ocean Emission Effects on Aerosol-Cloud Interactions: Insights from Two Case Studies

Table 2

Statistical summary of the ACI_r analysis shown in Figure 3. The numbers reported below represent ratios of a particular parameter between periods of relatively high chlorophyll A (>0.3 mg m^-3; October–February) versus low chlorophyll A (<0.3 mg m^-3; April–August). The average and standard deviation calculations are based on 11 values representing individual LWP bins between 50 and 350 g m^-2. These results represent 27 months of data starting in June 2006 for the Southern Ocean region (42° S–60° S, 180° W–180° E). (AI = aerosol index; AOD = aerosol optical depth; ANG = Ångstrom exponent; 𝑟_𝑒 = cloud drop effective radius; min = minimum value; max = maximum value).
