DMT offers a large selection of airborne instruments. For more information, click on one of the links at left.
Our instruments have been mounted on research planes, commercial aircraft, helicopters, blimps, and unmanned aerial vehicles (UAVs). Our sonde instruments are lifted aloft by weather balloons.
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
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
Cloud Particle Spectrometer with Polarization Detection (CPSPD): This optical spectrometer measures the diameter of aerosol particles from approximately .65 to 30 micrometers. Output data include forward-scattering and two polarized back-scattering measurements.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
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
Precipitation Imaging Probe (PIP): This optical spectrometer measures the size and shape of particles from 100 to 6200 µm. 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
CFH sonde: The Cryogenic Frost Point Hygrometer (CFH) sonde accurately measures water vapor at elevations from the earth’s surface to the mid-stratosphere. The instrument has a significantly greater sensitivity to water vapor than standard radiosondes. More Info
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. More Info
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
Wideband Integrated Bioaerosol Sensor (WIBS): The WIBS provides highly sensitive measurements of mold and other bioaerosols. Its UV wavebands have been selected to optimize detection of common bioaerosols (tryptophan and NADH). More Info
Photoacoustic Extinctiometer (PAX): This is a sensitive, high-resolution, fast-response instrument for measuring optical aerosol properties relevant for climate radiative forcing and carbon particle sensing. More Info
Single Particle Soot Photometer (SP2): This is an ideal instrument for measuring black carbon, known as soot. It is the only probe in the world that directly measures the black carbon in individual aerosol particles. Its high sensitivity and fast response makes it the premier instrument for characterizing pollution sources and measuring black carbon in snow, ice or water. More Info
Photo-Acoustic Soot Spectrometer, Three Wavelength (PASS-3): The PASS-3 is a sensitive, high-resolution, fast-response instrument for measuring the absorption coefficient of aerosol particles. It uses three wavelengths (red, green, and blue) to enhance measurement capabilities. More Info
Passive Cavity Aerosol Spectrometer Probe (PCASP-100X): This airborne optical spectrometer measures aerosol particles in the 0.1 to 3 µm range. It is currently in use on research aircraft in more than 20 countries. More Info
Ultra-High Sensitivity Aerosol Spectrometer, Airborne (UHSAS-A): This airborne optical spectrometer measures aerosol particles in the 0.06 µm to 1 µm range. More Info
ECC Ozonesonde: The ECC Ozonesonde, originally developed by EN-SCI, is a sensitive, compact instrument that offers a cost-effective way to measure atmospheric ozone. More Info
Air Data Probe (ADP) and AIMMS-20: The ADP (pictured) senses air speed, altitude, angle-of-attack, side-slip, ambient temperature and relative humidity. The optional AIMMS-20 component adds a Differential GPS Module (GPS), with a full suite of aircraft position parameters. More Info
