摘要

The international research projectRECONCILE has addressed central questions regarding polar ozone depletion,with the objective to quantify some of the most relevant yet still uncertainphysical and chemical processes and thereby improve prognostic modellingcapabilities to realistically predict the response of the ozone layer toclimate change. This overview paper outlines the scope and the generalapproach of RECONCILE, and it provides a summary of observations and modelling in2010 and 2011 that have generated an in many respects unprecedented datasetto study processes in the Arctic winter stratosphere. Principally, itsummarises important outcomes of RECONCILE including (i) better constraintsand enhanced consistency on the set of parameters governing catalytic ozonedestruction cycles, (ii) a better understanding of the role of cold binaryaerosols in heterogeneous chlorine activation,(iii) an improved scheme ofpolar stratospheric cloud (PSC) processes that includes heterogeneousnucleation of nitric acid trihydrate (NAT) and ice on non-volatile backgroundaerosol leading to better model parameterisations with respect todenitrification, and (iv) long transient simulations with a chemistry-climatemodel (CCM) updated based on the results of RECONCILE that better reproducepast ozone trends in Antarctica and are deemed to produce more reliablepredictions of future ozone trends. The process studies and the globalsimulations conducted in RECONCILE show that in the Arctic, ozone depletionuncertainties in the chemical and microphysical processes are now clearlysmaller than the sensitivity to dynamic variability.
