HTabsOverviewThe CCP is a multipurpose particle spectrometer that includes three Droplet instruments (CDP, CIP, and LWC) – plus temperature and relative humidity sensors – in a single package. Researchers use the CCP to obtain aerosol particle and cloud hydrometeor size distributions. Key Features All-purpose & easy to use Get five measurements packaged into a single canister to enable optimized measurement of cloud particles prior to and during transition to precipitation. Comprehensive measurements 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. Particle-by-particle (PBP) data 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). Detailed particle imaging options Use the optional grayscale imaging and fine-resolution features (for the CIP) to get more clarity on particle composition. Improved functionality options 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.
