A reconstruction of the past trend of atmospheric CO based on firn air samples from Berkner Island, Antarctica
International audience Although for several atmospheric trace gases trends over the past 100 year have been reconstructed using firn air analyses, little is known about one of the chemically most significant trace gases, namely CO. Among the 3 Antarctic drilling expeditions reported, the one from Be...
