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). Observations will be applied in modeling research to simulate Arctic wildfires, and to assess climate-change induced increase in Arctic wildfires and their feedbacks on the Arctic environment. This dataset is an archive of methane, carbon monoxide, carbon dioxide, and VOCs (ethane, ethyne, methyl-chloride, acetonitrile, propane, iso-butane, n-butane, iso-pentane, n-pentane, benzene, toluene) ambient air mixing ratios collected at GEOSummit since 2018. We aim to update this dataset regularly.
