The vertical distribution of particulate Na and Cl in a marine atmosphere

This is the authors' abstract. We don't add key points for this paper.

The vertical distributions of Na and Cl in the marine atmosphere near the Bahamas were measured on five consecutive days. The aerosols were sampled isokinetically from an aircraft at 8 or 10 different altitudes between 75 and 2000 m. The weights of Na and Cl in each sample were determined by neutron activation analysis. Since the Cl/Na ratio in the aerosols was close to that in seawater, it was concluded that these elements were present as sea salt. The concentrations of Na + Cl ranged from 4–7 μg/m3 at 75 m to about 0.5 μg/m3 at 2000 m.
