Is chlorophyll-a the best surrogate for organic matter enrichment in submicron primary marine aerosol?
Initial efforts toward developing a combined organic-inorganic sea spray source function parameterization for large-scale models made use of chlorophyll-a (Chl-a) and wind speed as input parameters to combine oceanic biology and atmospheric dynamics. These studies reported a modest correlation coeff...
