Cloud Combination Probe (CCP)

Advantage Characteristics

Use the optional grayscale imaging and fine-resolution features (for the CIP) to get more clarity on particle composition. Reduce the incidence of particle artifacts with optional Korolev anti-shatter tips (CIP feature), and keep your CIP instrument performing optimally with optional 8 VDC or 115 VAC anti-ice heaters. Get five measurements packaged into a single canister to enable optimized measurement of cloud particles prior to and during transition to precipitation.

Get more precise information on individual particle sizes with the optional PBP feature – including particle size in digital counts, individual particle time with μsec resolution, and inter-arrival particle time (IPT). See data on aerosol particle and cloud hydrometeor size distributions from 2 μm to 50 μm, two dimensional images and precipitation size distributions from 25 μm to 1550 μm (or 2 μm to 930 μm if the CIP component is ordered with 15-μm resolution), and liquid water content from 0.05 g/m3 to 3 g/m3.
