ATom  

Definition

  • The Atmospheric Tomography Mission (ATom) is a NASA Earth Venture Suborbital-2 mission to study the impact of human-produced air pollution on greenhouse gases and on chemically reactive gases in the atmosphere. ATom deployed an extensive gas and aerosol payload on the NASA DC-8 aircraft for systematic, global-scale sampling of the atmosphere, profiling continuously from 0.2 to 12 km altitude. Around-the-world flights were conducted in each of four seasons between 2016 and 2018. (en)

Reductions of atmospheric concentrations of methane (CH4), tropospheric ozone (O3) and black carbon (BC) aerosols are effective measures to slow global warming and to improve air quality. Airborne instruments will look at how atmospheric chemistry is transformed by various air pollutants and at the impact on CH4 and O3. Mitigation of these short-lived climate forcers is a major component of current international policy discussions. language code: en);
