| Name | DMT dual-channel Cloud Condensation Nuclei Counter |
| Acronym | CCN-Counter |
| Manufacturer | Droplet measurement technologies |
| Manufacturer website | http://www.dropletmeasurement.com/products |
| Operated by | FAAM |
| Operated onboard |
| Name | Condensation Particle Counter (CPC) |
| Acronym | Condensation Particle Counter |
| Measured parameter | Number concentration of submicrometer aerosol particles |
| Operating principle | The particles are detected and counted by a simple optical detector after a supersaturation vapor (butanol or water) condenses onto the particles, causing them to grow into larger droplets. The CPC uses a (laser diode) light source, a condensing lense, an internal microprocessor control, volumetric flow control and a front panel display. |
