Atmospheric tracers for Arctic wildfires, air pollution, atmospheric chemistry, and climate change at GEOSummit, Greenland, from January 2018 to March 2021

There has been an unprecedented increase in Arctic wildfire occurrences in recent years. This Arctic Observing Network (AON) project focuses on the study of Arctic tundra wildfires through continuous observations of atmospheric fire tracers, including carbon monoxide, methane, and a series of volatile organic compounds (VOCs) monitored at the Greenland Environmental Observatory at Summit (GEOSummit). This dataset is an archive of methane, carbon monoxide, and carbon dioxide ambient air mixing ratios from May 2019 to March 2021, and of VOCs (ethane, propane, iso-butane, n-butane, acetylene, iso-pentane, n-pentane, n-hexane, benzene, toluene) ambient air mixing ratios from January 2018 to March 2020.
