TL;DR: The authors assesses the skill of current-generation global atmospheric chemistry models in simulating the observed present-day tropospheric ozone distribution, variability, and trends using a range of model evaluation techniques, and demonstrate that global chemistry models are broadly skillful in capturing the spatio-temporal variations of troposphere ozone over the seasonal cycle, for extreme pollution episodes, and changes over interannual to decadal periods.

TL;DR: The linkage between La Niña and western US stratospheric intrusions can be exploited to provide a few months of lead time during which preparations could be made to deploy targeted measurements aimed at identifying these exceptional events.

TL;DR: In this paper, the authors used 76 tree-ring collections spanning approx. 840 000 sq km and 5327 tree recruitment dates spanning approx 1.4 million sq km across the humid eastern United States.

TL;DR: In this article, the authors developed a multiple linear regression model to test whether ozone depleting substances (ODS) including chlorofluorocarbons and halons) had a measurable effect on total ozone values observed by the global network of ground-based instruments.

TL;DR: The determination accuracy of the Universal Thermal Climate Index (UTCI) is investigated, especially the UTCI uncertainties due to uncertainties in radiation fluxes, whose impacts on UTCI are evaluated via the mean radiant temperature (Tmrt).
