Short summary
We use a comprehensive set of diagnostics to investigate how two widely used modern reanalysis data sets might affect studies of lower stratospheric polar processing and ozone loss. Our results show that the agreement in temperature diagnostics between the two reanalyses improves over time in both hemispheres with increasing assimilation model inputs. This suggests that both data sets are appropriate choices for studies of polar processing in recent winters.
