CDP-ROBUST
CDP-ROBUST Combination Probe

The CDP-ROBUST is an in situ combination probe that combines the Cloud Droplet Probe (CDP) from Droplet Measurement Technologies and the Robust Water Content System Probe from Science Engineering Associates, Inc. The CDP measures cloud particles in the 2 to 50 µm size range to determine particle number concentration and size distribution. It operates at a wavelength of 658 nm and has a sampling frequency range of 0.04 to 20 seconds. The Robust probe measures both liquid water (LWC) and ice water content (IWC), providing direct measurements of the total water content (TWC) in clouds. It has a data rate of up to 20 Hz.
