Figure 4: Time-averaged organic aerosol surface concentrations for June 2006. Here “SOA” refers to secondary organic aerosol, “POC” to the primary organic carbon, and “total OC” to the total organic carbon. Also, “% SOA” refers to the relative contribution of isoprene SOA to the total organic aerosol mass (in percents) and “% marine SOA of SOA” to the relative contribution of marine SOA to the total SOA (in percents). The relative contributions are derived on the mass basis. See caption of Figure 1 for more information about latitudes and longitudes.
