The NASA Atmospheric Tomography (ATom) mission has embarked on a unique global transect of tropospheric chemistry, measuring a full suite of reactive gases and aerosols along curtains through the remote Pacific and Atlantic Ocean basins. These ocean basins comprise most of the photochemical activity of the troposphere, controlling the global abundances of many species such as methane and tropospheric ozone. By the time of this session, three of the four-season deployments will be completed and the datasets from the first two deployments will be publicly available. We invite presentations using ATom data, including in combination with other data, that examine the global scope of tropospheric gases and aerosols, particularly considering the evidence for and impacts of distant pollution sources on the oceanic atmosphere.
