Generic-Atmospheric State (Gen-AtmsState) refers to non-specific instruments on a platform that measure atmospheric state parameters. These are typically in situ sensors that measure temperature, pressure, humidity, and wind speed and direction. Types of atmospheric state instruments include thermometers, hygrometers, barometers, and anemometers.

Generic-Chemistry Related Sensors (Gen-Chemistry) refers to non-specific instruments on a platform used for atmospheric chemistry measurements. These are typically in situ analyzers that measure chemical compounds such as trace gases, halocarbons, volatile organic compounds, nitrates, aerosols, and other chemical species. Measurements can include mixing ratios, composition, particle size, optical properties, and particle size distribution.

Differential Optical Absorption Spectroscopy (DOAS) is a passive spectroscopic technique used to measure trace gas concentrations. It detects trace gases by measuring specific, narrow-band absorptions in the ultraviolet and visible spectra. DOAS is typically used to detect ozone (O3), nitrogen dioxide (NO2), formaldehyde (CH2O), and sulfur dioxide (SO2). It is suitable for both airborne and ground-based applications.

Generic-Radiometers refer to non-specific radiometers on a platform. These are typically passive microwave radiometers that measure brightness temperature. Radiometers can be used to retrieve temperature and water vapor profiles, soil moisture content, ocean salinity, precipitation and cloud properties, and vegetation.

Spectrometers are instruments that separate and analyze the spectral components of a substance. They typically measure electromagnetic radiation that has been reflected, absorbed, or transmitted by a sample. Spectrometers operate across the ultraviolet to infrared spectrum. The most common types include optical, nuclear magnetic resonance, and mass spectrometers. They can be deployed on aircraft, research vessels, vehicles, and other ground-based platforms.

The Aethalometer is an in situ aerosol measurement device made by Magee Scientific. It can be used on both airborne and ground-based platforms. It collects aerosols on a filter tape and measures the attenuation of transmitted light to assess black carbon concentrations. The Aethalometer operates across seven optical wavelengths (370, 470, 520, 590, 660, 880, and 950 nm) and provides data at 1 Hz. It has a measurement range of 0-500 μg per cubic meter and a resolution of 0.1 μg per cubic meter.
