The Campaign
The Atmospheric Boundary Layer Experiment (ABLE) was a NASA campaign that investigated how emissions from the biosphere interacted with the boundary layer. ABLE included five deployments during the boreal spring and summer from 1984 to 1990 across three different study regions: the Tropical North Atlantic Ocean, the Amazon Rainforest, and the Arctic areas of North America. NASA’s Electra aircraft was equipped with in situ and remote instruments to gather measurements of trace gases, ozone, and aerosols in the atmosphere. ABLE was funded by NASA’s Tropospheric Chemistry Program and was part of the Global Tropospheric Experiment (GTE) program.

The Differential Absorption Lidar (DIAL) is an airborne lidar system developed at NASA’s Langley Research Center (LaRC). It uses four lasers to detect lidar backscatter and provide profile measurements of ozone and aerosols in the atmosphere. DIAL operates in the ultraviolet (289-300 nm) for ozone detection and in the visible (572-600 nm) and infrared (1064 nm) for aerosols. It has a horizontal spatial resolution of approximately 15 km and a measurement accuracy of 5 ppbv.

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 Turbulent Air Motion Measurement System (TAMMS) is an in situ airborne sensor used to gather aircraft navigation information. TAMMS consists of several subsystems, including pressure transducers and temperature sensors, an aircraft inertial navigation system, a central data acquisition system, and water vapor and other gas sensors. It provides measurements of aircraft position, flight level winds, temperature, pressure, and water vapor. TAMMS has a typical sampling frequency of less than 1 second and a spatial resolution of 5 meters.

The Differential Absorption Carbon monOxide Measurements (DACOM) is an airborne in situ spectrometer system. It uses the differential absorption technique and an infrared tunable diode laser (TDL) to collect measurements of nitrous oxide (N2O), carbon dioxide (CO2), carbon monoxide (CO), and methane (CH4) in the atmosphere. DACOM operates across the 4.7, 4.5, and 3.3 μm wavelengths to access the absorption lines for CO, N2O, and CH4. It has a measurement frequency of 5 Hz and a precision of about 1 ppbv.
