The Cloud Spectrometer and Impactor (CSI) combines the counterflow virtual impactor with a new lightweight cloud droplet probe to allow for detailed studies of total condensed water (TCW), liquid and ice, in clouds. The CSI can measure TCW from ~ 1 mg/m3 to several g/m3 depending on the configuration; in addition particle sizes from 2 to 50 μm are resolved with the droplet probe. The instrumentation can be mounted externally on most aircraft.

Condensation Particle Counters (CPCs) are in situ sensors that measure aerosol particle concentration. CPCs measure aerosol concentration by condensing fluid onto the particles, allowing them to grow to more detectable sizes for optical scattering. Typically, CPCs can detect particles with a size range of 7 nm-3 μm, can measure particle concentrations up to 100,000 particles/cc, and can provide measurements at 1-second intervals. CPCs are manufactured by TSI Incorporated and can be deployed on airborne, shipborne, and ground-based platforms.

PCASP operates at the 632 nm wavelength and has a typical sampling rate of 10 Hz.

The PVM-100 instrument developed by Gerber Scientific conducts particulate volume measurements using a forward-scattering laser spectrometer. A laser is used to measure the forward light scattering within a 3 cubic centimeter volume, and a liquid water content is inferred from the calculated scattering flux of the volume. Droplets in the 3-50 µm Diameter range can be detected with the instrument, and measurements can be taken up to 200 times a second.

The Cloud Aerosol and Precipitation Spectrometer (CAPS) is an in situ airborne spectrometer manufactured by Droplet Measurement Technologies. It combines the Cloud Imaging Probe (CIP), the Cloud and Aerosol Spectrometer (CAS), and the Hotwire Liquid Water Content (LWC) Sensor into one instrument. CAPS measures the size distribution of aerosol, cloud, and liquid droplets for particles between the sizes of 50-1600 μm at a time resolution of 1 Hz. It can also record images of cloud particles and provide measurements of temperature, pressure, and LWC.

A TUNABLE DIODE LASER is a solid-state laser in which as lasing is achieved by passing an injection current through the active region of a semiconductor across the p-n junction; tunable meaning it is used with a technique based upon the measurement of light absorption upon irrigating a sample using a tunable laser source.
