Monthly averaged Antarctic total ozone column for October, Soloman 2016


Monthly averaged Antarctic total ozone column for October, from SBUV and South Pole station observations and a series of model calculations. Total ozone data measured at the geographic South Pole are from Dobson observations (filled circles) for October, when there is not sufficient sunlight for the Dobson. SBUV data for each month are compared with model runs averaged over the polar cap latitude band that is accessible by the instrument; South Pole station data are compared with simulations for 85°S to 90°S.

Strategic Direction: Chemical Climate

1. In order to improve prediction of the Earth system across scales, quantify the chemical and dynamical coupling mechanisms between the upper and lower atmosphere.

2. In order to inform mitigation policies, identify the life cycle of short-term climate pollutants (reactive species and aerosols) and their impacts on climate.

3. In order to characterize the resilience of the Earth system to natural and anthropogenic disturbances, evaluate the role of chemical and biogeochemical feedbacks in the climate system.

Focus 2 on Chemical Climate: The Influence of the Middle and Upper Atmosphere on Climate Variability and Change.
