Human skin oil: a major ozone reactant indoors

Much of the ozone that enters buildings reacts with human skin oils, both on occupants and on other surfaces. Products of these reactions influence human chemical exposures.

Variability in air quality, ozone formation potential by VOCs, and associated air pollution attributable health risks for Delhi's inhabitants

The present long-term study has been conducted with dual objectives: firstly, to monitor the spatio-temporal variation of ambient air quality parameters and secondly, to evaluate the impact of air pollutants on the Delhi population.

Performance of machine learning for ozone modeling in Southern California during the COVID-19 shutdown

We combine machine learning (ML) and geospatial interpolations to create two-dimensional high-resolution ozone concentration fields over the South Coast Air Basin for the entire year of 2020.

Improving model representation of rapid ozone deposition over soil in the central Tibetan Plateau

Ozone deposition velocity with a daily mean of 0.49 cm s−1 was observed in the Tibetan Plateau and rationalized by local meteorological and soil conditions. Our research suggested widespread ozone deposition velocity over soil of 0.1–0.7 cm s−1.

Emerging investigator series: a machine learning approach to quantify the impact of meteorology on tropospheric ozone in the inland southern California

The role of meteorology in facilitating the formation and accumulation of ground-level ozone is of great theoretical and practical interest, especially due to emissions shifts and changing global climate.

Observations of coastal dynamics during lake breeze at a shoreline impacted by high ozone

Understanding the role of lake breeze in vertical ozone profiles using unmanned aerial systems at a shoreline location. Vertical profiles show gradients in ozone with higher ozone in areas of steep temperature inversion.

Unraveling the interaction of urban emission plumes and marine breezes involved in the formation of summertime coastal high ozone on Long Island

The different mechanisms for high ozone cases at the north shore vs. the south shore of Long Island, New York are influenced by the interplay of urban plumes with different coastal meteorological flow patterns.

A conceptual model of northern midlatitude tropospheric ozone

The average (climatic) seasonal pattern of ozone in the northern mid-latitude troposphere is explained by a very simple model. Reference to such basic models is a valuable tool for the interpretation of complex simulations and measurements.

Elucidating the impacts of COVID-19 lockdown on air quality and ozone chemical characteristics in India

We highlight the contribution of inter-annual meteorology and emissions (dust, biogenic, and biomass burning) and COVID-19 lockdown emissions to the changes in aerosols and ozone, and provide a detailed ozone chemistry analysis in northern India.

An analysis of 30 years of surface ozone concentrations in Austria: temporal evolution, changes in precursor emissions and chemical regimes, temperature dependence, and lessons for the future

We analyse the evolution of surface ozone in Austria for 1990–2019 and investigate effects of changes in precursor emissions and climate warming. Our results show that ozone burdens remain a health problem despite reductions in precursor emissions.

About this collection

This collection highlights leading research published in Environmental Science: Atmospheres investigating tropospheric ozone's role in our atmospheric environment. Studying tropospheric ozone is crucial as it plays a dual role acting as a pollutant harmful to human health and a potent greenhouse gas exacerbating climate change. Understanding its sources, interactions, and dynamics helps in formulating effective air quality regulations and mitigating climate impacts.
