DMT Cloud Spectrometer and Impactor

Greg Kok

Droplet Measurement Technology

Boulder, Colorado

The Cloud Spectrometer and Impactor (CSI) combines the counter flow virtual impactor with a new lightweight cloud droplet probe to allow for detailed studies of total condensed water (TCW), liquid and ice, in clouds. The CSI can measure TWC from ~ 1 mg/m³ to several g/m³ depending on the configuration; in addition particle sizes from 2 to 50 μm are resolved with the droplet probe. The instrumentation can be mounted externally on most aircraft. A demonstration of the instrumentation will be conducted.
