Details

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)

Removed sentence on China

Chinese section has been added to the API article with current information. Shaoquan (talk) 10:58, 28 August 2008 (UTC)

Cleanup Introduction

Introduction is cluttered and detailed. Make more broad and previewing. Needs a definition. Freefighter (talk) 01:55, 22 January 2009 (UTC)

See how this set of edits worked out. The article should now be in a proper wikipedia format, but it needs a slew of references. Thegreatdr (talk) 21:47, 9 February 2009 (UTC)

Scales

For some reason, the various scales are in different table formats for each country. If this article is ever going to be improved to B class, let alone GA, all the tables need to be in the same format. Thegreatdr (talk) 21:49, 9 February 2009 (UTC)

Needs and lacks tying numbers to objective numbers, e.g., ppm.

can you mention this Air Quality Forecasting website?

this site produces a daily air quality forecast

This is an US example of a service provided in many countries. It is only marginally related to the topic, but could well be discussed in an article on Air quality forecasting. Gabriel Kielland (talk) 22:15, 7 January 2009 (UTC)

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)

Proprietary site that requires javascript to see forecast, instead of national map denies information outside NY City without viewer giving personally identifiable information, forecast is so general as to be useless -- no breakout of pollen, mold, pollution, etc. Sly insertion of advertising, even into this discussion page, should be cleaned. — Preceding unsigned comment added by 66.167.61.181 (talk) 17:12, 4 September 2011 (UTC)

Change redirect of Air quality to Air Quality Index

Air Quality Index is a scale of determining Outdoor Air Quality and not Air Quality itself.

Proposal:

Stop redirecting Air Quality to Air Quality Index. Freefighter (talk) 01:51, 22 January 2009 (UTC)

I agree, but writing the Air quality article proper entails a lot of work. Will you start? Gabriel Kielland (talk) 18:18, 22 January 2009 (UTC)

This article is not a very good AQI article because it does not tie colors to pollutant levels, let alone to health, and hence fails to infuse any meaning into AQI. It is no excuse for an Air Quality article at all. — Preceding unsigned comment added by 66.167.61.181 (talk) 17:20, 4 September 2011 (UTC)

Proposed move to Air Quality Index

This article is not about air quality, it is about air quality indices. This article should be moved, and the page Air Quality should redirect to air pollution.--NHSavage (talk) 18:39, 19 July 2012 (UTC)

Agreed. The article used to be called Air Quality Index and was renamed without discussion. -- JTSchreiber (talk) 05:40, 26 July 2012 (UTC)

Needs and lacks information about air quality levels

Overall, not about air quality in meaningfully intelligible sense, but about colors of various AQI charts artificially divorced from objective equivalent measures. Thus obscures that Canada, for example, deems air unhealthy that in China is officially deemed as good. — Preceding unsigned comment added by 66.167.61.181 (talk) 17:04, 4 September 2011 (UTC)

I agree. I have included this information for the UK. I will try and find it out for other countries.--NHSavage (talk) 19:14, 1 August 2012 (UTC)

Requested move

The following discussion is an archived discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review. No further edits should be made to this section.

The result of the move request was: moved to Air quality index. Jenks24 (talk) 08:49, 6 August 2012 (UTC)

Air quality → Air Quality Index –This article used to be called Air Quality Index but was moved without discussion at 20:49, 11 March 2011. The content of this article is almost exclusively on Indices of Air Quality not Air Quality itself. Air Quality would be better as redirect to Air Pollution as the two terms are almost antonyms. --NHSavage (talk) 20:39, 26 July 2012 (UTC)

I agree with the move, because the article only talks about indices. But it should be in lowercase "Air quality index" because it's a generic name, per MOS:CAPS. --Enric Naval (talk) 16:25, 3 August 2012 (UTC)

Air quality index seems reasonable to me.--NHSavage (talk) 12:04, 4 August 2012 (UTC)

The above discussion is preserved as an archive of a requested move. Please do not modify it. Subsequent comments should be made in a new section on this talk page or in a move review. No further edits should be made to this section.

Some useful references

Some additional references which might be useful for this article would be:

Dumped here in the (probably vain) hope that someone else will use them before me.--NHSavage (talk) 19:01, 8 August 2012 (UTC)

Merger proposal

I propose that Pollutant Standards Index be merged into Air quality index. I think that the content in the Pollutant Standards Index mostly duplicates sections of this article, apart from the part on Malaysia, which can easily be included here.NHSavage (talk) 20:43, 8 August 2012 (UTC)

One other comment - there are some other articles on specific indices, which vary in quality but are fine in concept. This article mixes together several different indices and so duplicates air quality index.--NHSavage (talk) 06:01, 9 August 2012 (UTC)

Globalize History

I have made the information on the history of the air pollution index in the US a separate section. However, this does mean it is very skewed to the US. If we could add some information on the development and adoption in other countries it would be good.--NHSavage (talk) 19:15, 19 January 2014 (UTC)

How to organise the information?

This article is moving towards a general description of air quality indices which is good. I am unsure about what to do about the different indices used across the world. One option would be to just make a section List of air quality indices by country and link to the articles where they exist, or create them where they don't. This might lead to some very stubby articles though (see Pollutant Standards Index). The other option is to keep the descriptions broadly as they are but trying to edit them to include common information and a similar level of detail. In either case, I think it would be useful to have an overview of similarities and differences between indices. A third option just occurred to me which would be to have a table with country, name of index (linked if article exists) and pollutants included. Any comments? --NHSavage (talk) 20:32, 19 January 2014 (UTC)

Also if we go down the route of multiple articles for each different index, then we should probably make a new category or navbox.--NHSavage (talk) 20:50, 19 January 2014 (UTC)

I have now made a new category for Air quality index. I have added the existing pages to the category and will try and move things forward from there.--NHSavage (talk) 11:14, 9 February 2014 (UTC)

hong kong has just switched to use AQHI instead of API

http://www.gov.hk/en/residents/environment/air/aqhi.htm — Preceding unsigned comment added by 203.218.82.65 (talk) 01:27, 6 January 2014 (UTC)

Thank you for that information - I have updated the Air Pollution Index page and I will get around to this page RSN.--NHSavage (talk) 11:16, 9 February 2014 (UTC)

Done. Any additional improvements welcome of course.-NHSavage (talk) 19:13, 9 February 2014 (UTC)

Photo of Smog in Almaty is photoshoped !!!

Image of smog in Almaty is modified in photoshop, contrast is enhanced, colours are altered. Here is original: https://www.facebook.com/photo.php?fbid=642704032468224&set=p.642704032468224&type=3&theater where it is absolutely unclear wether it is a fog with a smog, or just a fog. So this photo is not real and therefore misleading, I would suggest to find some other picture of smog. Also, the title of the picture saying that AQI is high in Almaty but where is the source of this information? I can't find AQI for Almaty... — Preceding unsigned comment added by D.Jurin (talk • contribs) 14:59, 18 November 2015 (UTC)

Both images were uploaded by the same person, Igors Jefimovs. He uploaded to Facebook soon after taking the photo, and uploaded to Wikimedia two weeks later. The photo on Wikimedia has had its contrast increased, so the pollution doesn't look as bad as on the Facebook photo; but both clearly show smog. --pmj (talk) 01:39, 24 May 2017 (UTC)

See the Easiness effect. The present dumbed-down version of the article which excludes the definitions of the AQI levels does not make much sense. Would weather forecasts with temperatures restricted to "sub-freezing/freezing/cold/mild/hot/sweltering" be an acceptable replacement for numerical temperature forecasts? Anyway, I'm searching for at least the definition of one of the AQI scales... Some of the obvious sites are quite dumbed-down. Boud (talk) 21:47, 18 February 2018 (UTC)

The European CAQI is done as a rough first draft. It turned out that the existing prose content of the Europe section of this Wikipedia article was copy/pasted material, so I've replaced it completely. Boud (talk) 23:54, 18 February 2018 (UTC)

Unused reference

The following book was cited in the Europe section, but the prose content of the Europe section that claimed to use this was all copy/pasted content from airqualitynow.eu - so it's not clear what information supposedly came from the book: Garcia, Javier; Colosio, Joëlle (2002). Air-quality indices : elaboration, uses and international comparisons. Presses des MINES. ISBN 2-911762-36-3. If someone has access to it, feel free to restore the reference and use information from it, not text from it. It sounds like it might be quite out of date, however - 15 years' old. Boud (talk) 23:47, 18 February 2018 (UTC)

EAQI

The Europe section now has a lot about the CAQI, but only one sentence about the EAQI, which was defined more recently. A good TODO task would be to add info for the EAQI. Boud (talk) 01:01, 19 February 2018 (UTC)
