The Harvard QCLS (DUAL and CO2) instrument package contains 2 separate optical assemblies and calibration systems, and a common data system and power supply.
The QCLS instrument package was used to measure atmospheric concentrations.
The UCATS system is three different instruments in one enclosure: a two-channel chromatograph with electron capture detectors (one measures N2O and SF6, the other measures CH4, H2 and CO), a tunable diode laser instrument for H2O, and a dual-beam O3 photometer.
A new dataset was collected using the Unmanned Aircraft Systems (UAS) Chromatograph for Atmospheric Trace Species (UCATS).
Dry-air mole fraction of methyl bromide measured in Programmable Flask Package samples taken during Atom-2 flights in January-February 2017.
Two new instrument datasets available from the Atmospheric Tomography Mission (ATom).
Mixing ratio of CFC-11 measured by Whole Air Sampler (WAS) during ATom-4 flights in April-May 2018.
The UC-Irvine Whole Air Sampler (WAS) instrument was used during the Atmospheric Tomography (ATom) mission.
Measurements of atmospheric acetone concentration from samples collected by the Trace Organic Gas Analyzer (TOGA) during ATom-3 flights in 2017.
Concentrations of volatile organic compounds (VOCs), measured by the Trace Organic Gas Analyzer (TOGA), are available.
Measurements of atmospheric carbon dioxide concentration from flasks collected by the Medusa system during ATom-4 flights in 2018.
NASA's Atmospheric Tomography (ATom) campaign collected whole air samples and measurements of formaldehyde during round-the-world flights.
Example cross-sections of CO2, O2, and APO (O2 + 1.1 * CO2) measured by AO2 (interpolated flight track data) and the Medusa flask sampler (filled circles) during the Pacific southbound flights of ATom-4 in April and May 2018.
Data collected by the Airborne Oxygen Instrument (AO2) during the Atmospheric Tomography (ATom) airborne campaigns are now available.
The NASA DC-8 aircraft was used for the ATom missions.
Aerosol data collected during Atmospheric Tomography Mission (ATom) will inform on new particle formation occurrence in the tropics.
The Atmospheric Tomography (ATom) Mission is an Earth Venture Suborbital-2 mission to measure greenhouse gases and human-produced air pollution in remote areas.
Five new datasets from ATom provide measurements of greenhouse gases and human-produced air pollution from 2016 to 2018.
The NOAA Single Particle Soot Photometer (SP2) is a laser-induced incandescence instrument primarily used for measuring the black carbon mass content of individual particles.
Black carbon concentrations were measured over remote regions of the Earth during NASA's Atmospheric Tomography (ATom) Mission.
