The Campaign
The Atlantic Stratocumulus Transition Experiment (ASTEX) was a field campaign aimed at better understanding the physical and radiative properties of boundary layer and marine stratocumulus clouds. ASTEX was part of the First ISCCP Regional Experiment (FIRE) project, which took place from 1986 to 1998. It involved a single deployment from May to June 1992 across the Azores Islands. Researchers used aircraft, vessels, and ground-based platforms to gather measurements of cloud and aerosol characteristics. ASTEX was a collaborative effort between NASA and the Office of Naval Research.

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.

A pyrgeometer is a ground-based or airborne passive radiation sensor. It measures downward and upward longwave radiation in the 4-50 μm spectral range. Pyrgeometers measure changes in resistance/voltage using a thermopile sensor to determine longwave radiation. These measurements can be used to calculate the infrared radiation flux. Pyrgeometers are typically used for climatological, meteorological, and agricultural applications.

Conductivity, Temperature, and Depth (CTD) sensors are in situ instrument packages 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 at specific water depths based on the researcher's needs.

Rain gauges are ground-based instruments that measure liquid precipitation amounts directly over a specified period. Different rain gauges, such as tipping buckets and weighing gauges, collect and record data in various ways. Because of their small size and easy setup, rain gauges can be placed in different locations and are often used alongside other precipitation instruments like disdrometers to gather more details, such as precipitation rate and size distribution.

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.

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