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

Table 1

Summary of correlative relationships between ocean chlorophyll A, marine aerosols, and stratocumulus clouds during the three-week MASE II field campaign in July 2007, during which chlorophyll A levels ranged between 1.01–3.58 mg m-3. Owing to the short duration of the study and limited measurements of chlorophyll A all data have been averaged to correspond to the time durations corresponding to each chlorophyll A measurement. Details related to the mean, standard deviation, and range of values of these parameters are discussed in detail by Sorooshian et al. [17]. (Chl A = chlorophyll A; DEA = diethylamine; MSA = methanesulfonate; Nd = cloud drop number concentration; TKE = turbulent kinetic energy).
