Tropospheric ozone is a key air pollutant and greenhouse gas. Its fate strongly depends on
meteorological conditions and therefore subject to climate change influences. Such …

The goal of the Tropospheric Ozone Assessment Report (TOAR) is to provide the research
community with an up-to-date scientific assessment of tropospheric ozone, from the surface …

The Tropospheric Ozone Assessment Report (TOAR) is an activity of the International Global
Atmospheric Chemistry Project. This paper is a component of the report, focusing on the …

Ozone holds a certain fascination in atmospheric science. It is ubiquitous in the atmosphere,
central to tropospheric oxidation chemistry, yet harmful to human and ecosystem health as …

Ozone forms in the Earth's atmosphere from the photodissociation of molecular oxygen,
primarily in the tropical stratosphere. It is then transported to the extratropics by the Brewer …

A big gap exists between current air quality in China and the World Health Organization
(WHO) global air quality guidelines (AQG) released in 2021. Previous studies on air …

Rapid population growth and industrialization have driven substantial increases in Asian
ozone precursor emissions over the past decade, with highly uncertain impacts on regional …

Our understanding of the processes that control the burden and budget of tropospheric
ozone has changed dramatically over the last 60 years. Models are the key tools used to …

Tropospheric ozone is an important greenhouse gas, is detrimental to human health and
crop and ecosystem productivity, and controls the oxidizing capacity of the troposphere …

Evidence suggests deep stratospheric intrusions can elevate western US surface ozone to
unhealthy levels during spring. These intrusions can be classified as 'exceptional events' …
