TL;DR: The Tropospheric Ozone Assessment Report (TOAR) is an activity of the International Global Atmospheric Chemistry Project as mentioned in this paper, which provides a detailed view of ozone in the lower troposphere across East Asia and Europe.

TL;DR: The nature and timescales of ozone recovery are discussed, the extent to which it can be currently detected in different atmospheric regions is explored, and climate change is masking ozone recovery from ozone-depleting substances in some regions and will increasingly affect the extent of recovery.

TL;DR: The construction of the Stratospheric Water and Ozone Satellite Homogenized (SWOOSH) database, which includes vertically resolved ozone and water vapor data from a subset of the limb profiling satellite instruments operating since the 1980s, is described and the ancillary information stored in SWOOSH that can be used in future studies of water vapor and ozone variability is presented.

TL;DR: In this paper, the vertical distribution of ozone is reported and compared for a number of new and recently revised data sets, and the authors examine the periods before and after the peak to see if any change in trend is discernible in the ozone record that might be attributable to a change in the EESC trend, though no attribution is attempted.

TL;DR: In this paper, various ozone measurement methods and ozone datasets are reviewed and selected for inclusion in the historical record of background ozone levels, based on relationship of the measurement technique to the modern UV absorption standard, absence of interfering pollutants, representativeness of the well-mixed boundary layer and expert judgement of their credibility.
