ccn > Cloud Condensation Nuclei Particle CounterInstrument Type(s) > Baseline • External • Guest

The cloud condensation nuclei counter measures the concentration of aerosol particles by drawing an air sample through a column with thermodynamically unstable supersaturated water vapor that can condense onto aerosol particles. Particles that are activated, i.e., grown larger in the process, are counted and sized by an optical particle counter (OPC). In this way the CCN measures activated ambient aerosol particle number concentration as a function of supersaturation.

ARM operates both one- and two-column versions of the CCN.
