... in O 3 , CO 2 , H 2 O, nitrates, sulfates, and O-containing components of air pollution. The focus of Lyons (2001) was the transfer of O 3 MIF signatures to other oxygen-containing molecules in the atmosphere. We summarize this work below, and present updated results for Δ 17 O of several lower...
