The Arctic Climate Change, Economy, and Society (ACCESS) aircraft campaign is discussed, which aimed to study emissions from human activities such as oil and gas extraction and shipping within the context of other pollution sources that impact the region. The campaign utilized the Falcon 20 aircraft from the DLR that was equipped with atmospheric trace gas and aerosol instrumentation. During the ACCESS aircraft campaign 14 flights were performed, of which 9 flights were dedicated to studying Arctic air pollution. Most of the flights aimed to study pollution from low-altitude emission sources such as shipping and hydrocarbon extraction facilities. The large-scale synoptic situ-ation during the campaign was characterized by a persistent low pressure system that influenced large parts of northern Scandinavia, the Barents Sea, and the Norwegian Sea. The ACCESS aircraft campaign has provided one snapshot of current emissions from shipping and oil and gas facilities in one focus region.
