Ice and Cloud Nuclei

Cloud Condensation Nuclei Counter (CCN): This instrument counts cloud condensation nuclei (CCN). It is being used in laboratories to measure how different materials form cloud droplets, in urban environments to study how pollution affects cloud and precipitation formation, and in weather modification to determine when and where to seed clouds.

Spectrometer for Ice Nuclei (SPIN): This instrument is the first commercially available ice nuclei counter, with a particle detection range from 0.3 – 10 μm. Particle detection allows for individual particle sizing and discrimination of ice and water particles using polarization change in the scattered light. More Info

 

Cloud Particles

Cloud Droplet Probe (CDP-2): This miniature, lightweight, low-power cloud particle spectrometer measures droplets in the range of 2-50 µm in concentrations as high as 2000 particles/cm3. More Info

 

Cloud Imaging Probe (CIP): This optical spectrometer measures the size and shape of particles from 25 µm to 1550 µm, liquid water content from 0.01 to 3 g/3 and airspeed to 200 m/sec. More Info

 

Precipitation Imaging Probe (PIP): This optical spectrometer measures the size and shape of particles from 100 to 6200 µm. More Info

 

Cloud Combination Probe (CCP): This multipurpose particle spectrometer provides aerosol particle and cloud hydrometeor size distributions from 2 to 50 µm, precipitation size distributions from 25 µm to 1550 µm, and liquid water content from 0.05 to 3 g/m3. More Info

 

Cloud, Aerosol, and Precipitation Spectrometer (CAPS): This multipurpose particle spectrometer provides aerosol particle and cloud hydrometeor size distributions from 0.5 to 50 µm, particle shape (discrimination between water and ice), particle optical properties (refractive index), precipitation size distributions from 25 µm to 1550 µm, and liquid water content from 0.01 to 3 g/m3. More Info

 

Hot-Wire Liquid Water Sensor (LWC-300): This tiny sensor measures liquid water content (LWC) from 0.05 to 3 g/m3 and can be easily mounted on manned or unmanned aircraft, cooling towers, spray rigs and many other applications where the precise measurement of  LWC is needed. More Info 

 

Back-scatter Cloud Probe (BCP): This instrument's non-intrusive housing allows it to measure cloud particles with minimal airflow disruption. Back-scattering optics detect particles in the 7 - 75 µm range. More Info

 

Backscatter Cloud Probe with Polarization Detection (BCPD): measures cloud droplet size distributions, which are then used to derive the total number concentrations, liquid water content (LWC), median volume diameter (MVD), and effective diameter (ED).More Info

 

Aerosols

Ultra-High Sensitivity Aerosol Spectrometer (UHSAS): The UHSAS is an optical-scattering, laser-based aerosol particle spectrometer for sizing particles in the 0.06 – 1 µm range. The instrument counts particles in up to 100 user-specified sizing bins, with a resolution as fine as 1 nm/bin. This high sensitivity makes the UHSAS ideal for aerosol research and filter testing.
