A wide range of processes acting within and outside the winter polar vortices is coupled to the evolution of stratospheric ozone and other related constituents. Stratospheric Processes and their Role in Climate (SPARC), a core project of World Climate Research Programme (WCRP) has facilitated much of the current understanding of these types of processes.
Both dynamically-driven and chemically-driven processes contribute to variability in Arctic ozone. However, the extent to which each of these basic processes affect O3 varies strongly from year to year. To investigate the influence of chemical processes on the ozone distribution, and to monitor the ozone recovery in future, it is crucial to have continuous high-quality measurements of ozone and its related constituents (WMO, 2007).
The International Polar Year (IPY) program offered a unique opportunity to intensify and coordinate a wide range of scientific activities over the polar vortex, the location of key processes associated with ozone depletion and its eventual recovery.
We
documented the dynamics and chemistry of the polar vortices during the IPY.
facilitated analysis of available satellite and ground-based data.
provided a broad overview of polar observations and highlight observational features.
progressed toward a comprehensive picture of the structure and evolution of the Arctic polar vortex in the IPY.
