Data sets
Carbon monoxide (CO) Antarctic records from ice cores (DC12, ABN, Taldice), firn air (DE08-2, DSSW19K, DSSW20K, South Pole, ABN, Lock-In), and Mawson Station atmospheric history from -835 to 2021 CE X.

Short summary
We report on a 3000-year record of carbon monoxide (CO) levels in the Southern Hemisphere's high latitudes by combining ice core and firn air measurements with modern direct atmospheric samples. Antarctica [CO] remained stable (–835 to 1500 CE), decreased during the Little Ice Age, and peaked around 1985 CE. Such evolution reflects stable biomass burning CO emissions before industrialization, followed by growth from CO anthropogenic sources, which decline after 1985 due to improved combustion.
