Evidence for a CO increase in the SH during the 20th century based on firn air samples from Berkner Island, Antarctica
Trends of carbon monoxide (CO) for the past 100 years are reported as derived from Antarctic firn drilling expeditions. Only one of 3 campaigns provided high quality results. The trend was reconstructed using a firn air model in the forward mode to constrain age distributions and assuming the CO inc...
