So, does anyone have a world map picture showing air quality? http://www.esa.int/esaCP/SEM340NKPZD_index_1.html here's a picture

Does anyone know what actual concentrations of PM2.5 the AQI levels stand for? For example, what AQI level, as used in the US, corresponds to the WHO limit value of 10mug/m(3) for PM2.5? SuitGuy 21:48, 24 April 2007 (UTC)

There are inherent assumptions in your question that cannot be explained properly in the article. One way to resolve it is to have a new article Air quality explaining the limit values of each pollutant and how each of them is measured. The scope of this article is mainly how to best inform the public on a pollution event without explaining them details. This is done differently in different districts. More examples are found in the obvious merger candidate Air pollution index. Gabriel Kielland 19:58, 11 October 2007 (UTC)

This article does not list the pollutants the U.S/Canadian index actually measures, or specify how the scale is numerically calibrated to actual atmospheric concentrations. -- Beland 01:52, 7 July 2007 (UTC)
