The Riegl Laser Distance Meter is a ground-based lidar system manufactured by Riegl Laser Measurement Systems. It is a multi-purpose lidar system based on precise time-of-flight laser range measurements. It is used for accurate distance measurements in multi-target scenarios, such as measuring wave height. The Riegl Laser Distance Meter operates in the near-infrared (~0.9 μm) and has a measurement range of up to 1300 meters, depending on the operating mode. It has a measurement rate of up to 2000 Hz and can detect a maximum of about 3 to 4 targets.

LI-COR Gas Analyzers are in situ gas analyzers manufactured by LI-COR. They can be deployed on aircraft, research vessels, vehicles, balloons, and ground-based platforms. They measure trace gases such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor (H2O). Most models use Optical Feedback-Cavity Enhanced Absorption Spectroscopy (OF-CEAS) to collect measurements. LI-COR gas analyzers typically operate at 1 Hz and have an operating temperature range of -25 to 45 degrees Celsius.

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.

Conductivity, Temperature, and Depth (CTD) sensors are in situ instruments that measure water depth, pressure, salinity, temperature, and density in the ocean. CTD sensors can be deployed on various water-based platforms, including autonomous underwater vehicles (AUVs), buoys, gliders, and research vessels. When mounted on a vessel, CTD sensors are typically attached to a rosette and lowered to the seafloor to record water properties. These sensors typically sample at 30 Hz and can provide accurate measurements at specific water depths, tailored to the researcher's needs.

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.

Accelerometers are in situ sensors that measure the acceleration experienced by an object. They use electromagnetic sensing to detect the object's vibration. The vibration exerts a force on the sensor, producing an electrical charge that indicates the magnitude of the force and can be used to determine the acceleration. Accelerometers are typically used on aircraft to collect flight navigation information. They have also been deployed on research vessels and other water-based platforms, such as buoys.
