ATom

Atmospheric Oxygen and CO2 Concentrations

AO2 Measurements

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 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.

Black Carbon Aerosols from ATom

The SP2 instrument.

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.
