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

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.

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 various chemical compounds such as trace gases, halocarbons, volatile organic compounds, nitrates, aerosols, and other chemical species. Measurements can include mixing ratio, composition, particle size, optical properties, and particle size distribution.

The Compact-Optical Profiling System (C-OPS) is an in situ water-based radiometer system developed at Biospherical Instruments. It measures vertical profiles of ocean radiance and irradiance for depths of 150 to 300 m. It consists of two radiometers operating across the 250-1650 nm wavelength range. C-OPS has a typical sampling rate of 125 Hz and has a vertical resolution of less than 1 cm. It also consists of ancillary sensors that provide measurements of water temperature, pressure, and humidity.

This data will be added in future versions.
