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 ...
The WOUDC is operated by the Experimental Studies Division of the Meteorological Service of Canada (MSC) — formerly Atmospheric Environment Service (AES), Environment Canada and is located in Toronto. The WOUDC began as the World Ozone Data Centre (WODC) in 1960 and produced its first data publication of Ozone Data for the World in 1964.
The ozone layer visible from space at Earth's horizon as a blue band of afterglow within the bottom of the large bright blue band that is the stratosphere, with a silhouette of a cumulonimbus in the orange afterglow of the troposphere. The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet ...
Ground-level ozone (O 3), also known as surface-level ozone and tropospheric ozone, is a trace gas in the troposphere (the lowest level of the Earth's atmosphere), with an average concentration of 20–30 parts per billion by volume (ppbv), with close to 100 ppbv in polluted areas.
The ozone layer is contained within the stratosphere. In this layer ozone concentrations are about 2 to 8 parts per million, which is much higher than in the lower atmosphere but still very small compared to the main components of the atmosphere. It is mainly located in the lower portion of the stratosphere from about 15–35 km (9.3–21.7 mi ...
More than four in 10 people that live in the United States live in counties that have unhealthful levels of either ozone or particle pollution.
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.
