Some airborne observations of condensation nucleus concentration

  • G. J. Day
Article

Summary

The measurement of condensation nucleus concentration from an aircraft is considered and preliminary observations made with a photo-electric condensation nucleus counter discussed. It is concluded that at heights up to 6000 ft concentrations of condensation nuclei vary, from 200 cm−3 in clean maritime air to 5 × 103 cm−3 generally over large industrial areas and 35 × 103 cm−3 downwind of specific industrial sources. It appears that sea spray makes a contribution to the nucleus population.
