Surface ozone variability between two different Antarctic sites

Abstract

The study deals with the temporal and spatial variability of 365 days hourly mean surface ozone data for Syowa and McMurdo stations in Antarctica. The analyses not only show the seasonal and diurnal variation of surface O₃ in Antarctica, but also present statistics of surface O₃ variability on temporal scale. Diurnal variations of 3.9% and 0.8% have been observed in surface O₃ at Syowa and McMurdo, respectively. Surface O₃ during summer season at Syowa and McMurdo stations is observed to be 56% and 64%, respectively. The correlation between the surface O₃ concentrations at Syowa and McMurdo stations implies that the 18% of the variation is due to local weather conditions.
