Analysis of near-surface ozone variations in Terra Nova Bay, Antarctica
Abstract Ozone concentration measurements were made during December from 2001–2005 to quantify the contributions of different processes to near-surface ozone concentrations (O 3 ) in Terra Nova Bay, Antarctica. The average O 3 concentration was 20.3 ppbv. On days characterized by high solar radiatio...
