Cloud Condensation Nuclei on the Atlantic Seaboard of the United States

LAWRENCE F. RADKE 1 and PETER V. HOBBS 1

1 Atmospheric Sciences Department, University of Washington, Seattle 98195

Concentrations of cloud condensation nuclei measured along the East Coast from Virginia to Long Island ranged from 1000 to 3500 per cubic centimeter as compared to 100 per cubic centimeter in clean maritime air and 300 per cubic centimeter in continental air. The global anthropogenic production rate of cloud condensation nuclei may be comparable to the natural production rate; in some industrial areas cloud condensation nuclei are dominated by anthropogenic sources.
