Data assimilation is used in atmospheric chemistry models to improve air quality forecasts,
construct re-analyses of three-dimensional chemical (including aerosol) concentrations and …

From the earliest observations of ozone in the lower atmosphere in the 19th century, both
measurement methods and the portion of the globe observed have evolved and changed …

The evolution of tropospheric ozone from 1850 to 2100 has been studied using data from
Phase 6 of the Coupled Model Intercomparison Project (CMIP6). We evaluate long-term …

The Network for the Detection of Atmospheric Composition Change (NDACC) is an
international global network of more than 90 stations making high-quality measurements of …

Chemical ozone destruction occurs over both polar regions in local winter–spring. In the
Antarctic, essentially complete removal of lower-stratospheric ozone currently results in an …

In the lowermost layer of the atmosphere—the troposphere—ozone is an important source of
the hydroxyl radical, an oxidant that breaks down most pollutants and some greenhouse …

This analysis provides an up‐to‐date assessment of long‐term (1990–2010) rural ozone
trends using all available data in the western (12 sites) and eastern (41 sites) USA. Rather …

In this paper, we describe the construction of the Stratospheric Water and Ozone Satellite
Homogenized (SWOOSH) database, which includes vertically resolved ozone and water …

Throughout spring and summer 2020, ozone stations in the northern extratropics recorded
unusually low ozone in the free troposphere. From April to August, and from 1 to 8 kilometers …

Longer-term (ie, 20–40 years) tropospheric ozone (O3) time series obtained from surface
and ozonesonde observations have been analyzed to assess possible changes with time …
