Operator Manual: Cloud Condensation Nuclei (CCN-100) Counter – Single Column

The Droplet Measurement Technologies (DMT) Cloud Condensation Nuclei Counter (CCN) is based on the design of Dr. Greg Roberts of Scripps Institute of Oceanography and Dr. Athanasios Nenes of Georgia Institute of Technology. The technology is patent pending and licensed for manufacturing by Droplet Measurement Technologies.

The CCN measures aerosol particles called cloud condensation nuclei that can form into cloud droplets. The instrument operates by supersaturating sample air to the point the where the CCN become detectable particles, which are then sized using an optical particle counter and distributed into 20 bins. The DMT CCN counter can be operated on the ground or on aircraft.
