Atmospheric Tomography (ATom)

DOI: 10.5067/Aircraft/ATom/TraceGas_Aerosol_Global_Distribution

The Atmospheric Tomography Mission (ATom) will study the impact of human-produced air pollution on greenhouse gases and on chemically reactive gases in the atmosphere. 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.

Merged Datasets

A variety of merged files have been created for each flight date. The files include additional data such as numbered profiles and distance flown. In the case of data obtained over longer time intervals (e.g. flask data), the merge files provide (weighted) averages of 1s data to match the sampling intervals.

The merge files available for individual flights are:
