Cloud Spectrometer and Impactor (CSI)

Status

Operated By: 
PI

The Cloud Spectrometer and Impactor (CSI) combines the counterflow 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 TCW 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.

Instrument Type: 
Counterflow virtual impactor, Spectrometer (in situ)

Cloud Liquid Water Content, H2O (total)
Aircraft: 
C-130H - WFF, DC-8 - AFRC, WB-57 - JSC
