Ozoneweb is an EEA website on near real-time ozone. The website allows the general public to track air quality in a specific region and on a European level. The website displays ozone levels via a map of Europe. Background information on ozone and its health impacts are also provided. Users can monitor ozone levels in a neighbouring country or ...
Ozone-oxygen cycle in the ozone layer. The photochemical mechanisms that give rise to the ozone layer were discovered by the British physicist Sydney Chapman in 1930. Ozone in the Earth's stratosphere is created by ultraviolet light striking ordinary oxygen molecules containing two oxygen atoms (O 2), splitting them into individual oxygen atoms (atomic oxygen); the atomic oxygen then combines ...
This map tracks air quality near Detroit, and zoom out to see the rest of North America. Smoke from wildfires harmed the air in 2023. ... Higher ozone levels during the mid-afternoon and early ...
Low level ozone, or tropospheric ozone, is the most concerning type of ozone pollution in urban areas and is increasing in general. [60] Ozone pollution in urban areas affects denser populations, and is worsened by high populations of vehicles, which emit pollutants NO 2 and VOCs, the main contributors to problematic ozone levels. [61]
Levels of ground-level ozone, designated as one of six common air pollutants by the U.S. Environmental Protection Agency, can rise when compounded by heat and sunlight. Children, older adults and ...
In April 2023, the EPA finalized its "Good Neighbor Plan", which phases in tighter standards for NO x, using a cap and trade system during the summer "ozone season". This is intended to reduce ground-level ozone in non-attainment areas downwind of industrial sources like power plants, incinerators, and industrial furnaces, often in other states ...

Ozone levels stabilized by the mid-1990s and began to recover in the 2000s, as the shifting of the jet stream in the southern hemisphere towards the south pole has stopped and might even be reversing. [7] Recovery was projected to continue over the next century, with the ozone hole expected to reach pre-1980 levels by around 2075. [8]
