The Millimeter-wave Imaging Radiometer (MIR) was a passive airborne cross-track scanning radiometer developed by NASA. MIR measured brightness temperature across nine channels and was used for clouds, precipitation, and atmospheric water vapor studies. MIR operated near and around the following frequencies: 89, 150, 183, 220, and 325 GHz. It had an angular swath of 100 degrees and a sampling frequency of 3 seconds. MIR typically operated on NASA ER-2 aircraft before its retirement.

The Scanning High-resolution Interferometer Sounder (S-HIS) is an airborne cross-track scanning interferometer developed by the Space Science and Engineering Center at the University of Wisconsin-Madison. It measures the emitted thermal radiation between 3.3 and 18 microns at high spectral resolution. These measurements can be used to derive atmospheric profiles of temperature and water vapor in clear-sky conditions. S-HIS has a spatial resolution of 2 km and a swath width of 40 km at an altitude of 20 km at nadir. It has a sampling frequency of 0.5 s and an absolute radiance accuracy of 0.2 K.

The Johnson-Williams Cloud Water Meter (CWM) utilizes a resistance wire that has been calibrated to infer liquid water content (LWC) within clouds. Evaporation of water droplets that impact the wire lead to temperature variations of the wire which can be linearly correlated with liquid water content. Additionally, a second wire allows compensation of altitude, temperature, and speed for more accurate measurements. The CWM can be operated over LWC ranges between 0 and 6 grams per cubic meter and at air speeds between 50 and 150 meters per second. Collection efficiency for the instrument has been shown to decrease when water droplets are larger than 30 micrometers; making the probe more beneficial for small droplet usage.

If instrument mode or detailed specification information is not available, can use this entry for spectrometers of various types. A spectrometer is an instrument that measures a range of a characteristic for a given substance or wavelength. There are many different types of spectrometers. Some examples are mass spectrometers, spectrophotometers, and magnetic radiation spectrometers.

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.

Examples include: CO, CO2, NO, NO2, N2O, HNO3, HNO4, OH, H2SO4, CH3CN, O3, H2O, halocarbons, VOCs, nitrates, aerosols (including CCN), aerosol optical properties, etc...

The Forward Scattering Spectrometer Probe (FSSP) is an in situ airborne optical particle counter originally designed by Particle Measuring Systems, Inc. It provides particle size distribution by measuring the intensity of the light scattered by individual particles within the cloud. FSSP can detect particles within a diameter range of 0.5 to 47 μm. It operates at a wavelength of 633 nm and has a typical sampling frequency of 1 Hz.

Nephelometers are in situ airborne or ground-based optical sensors. They measure the total scattering and backscattering of aerosol particles in the atmosphere. Nephelometers operate across three wavelengths: 450 nm, 550 nm, and 700 nm, and have a typical time resolution of 1 Hz.

Ceilometers are ground-based, remote-sensing sensors that provide measurements of cloud ceilings and vertical visibility. They use either a laser beam or another light source to detect backscatter of clouds, precipitation, and aerosols. Ceilometers can provide detailed and accurate measurements in all types of weather conditions and have low operating costs. Ceilometers are typically used in boundary layer and cloud research applications.

Rain gauges are ground-based instruments that provide in situ measurements of liquid precipitation amounts over a set time. There are multiple types of rain gauges that each collect and record data differently such as the tipping bucket rain gauge and weighing precipitation gauge. Rain gauges can be deployed in various locations due to their relatively small size and easy set-up and are typically colocated with other precipitation instruments such as disdrometers to provide more details about precipitation being collected such as precipitation rate and size distribution.

Conductivity, Temperature, and Depth (CTD) sensors are in situ instrument packages that are used to measure water depth, pressure, salinity, temperature, and density in the ocean. CTD sensors can be deployed on various water-based platforms such as autonomous underwater vehicles (AUVs), buoys, gliders, or research vessels. When deployed on a vessel, CTD sensors are typically attached to a rosette and then lowered to the seafloor to measure water properties. CTD sensors have a typical sampling rate of 30 Hz and can collect precise measurements for a specific water depth depending on the researcher's needs.
