Can we get a scale bar? or legend? and what is being plotted here? and where does the data come from? what's the difference between the contours and the dots?<p>Clicking the big dots just takes me to a completely different page that doesn't have that much more information. I'd expect a popup on the map that tells me what the color/size of the dot means.
I am David, one of Plume Labs' founders. Thank you for all your feedback!<p>At Plume Labs we build tools to help people fend off pollution. This starts with an urban weather report (the Plume Air Report) that tells you when pollution will be high for a few hours or more in your city, and what you can do about it – timing your run, biking, activities with children – to take back control of your environment.<p>The map discussed here is a near realtime visualization of air pollution levels worldwide. The colors and the Plume Index are based on WHO recommendations. (Blue corresponds to levels below the W.H.O. yearly recommendations, light blue is below the W.H.O. daily recommendations etc.) The map takes into account the main pollutants (NO2, O3, PM10, PM2.5) and is based on measurements made in 11,000 monitoring stations worldwide along with air quality models for the areas that are not covered by monitoring stations.<p>More details as well as pollution predictions are available on the mobile version of the Plume Air Report<p>iOS => <a href="https://itunes.apple.com/en/app/plume-air-report-pollution/id950289243?mt=8" rel="nofollow">https://itunes.apple.com/en/app/plume-air-report-pollution/i...</a><p>Android => <a href="https://play.google.com/store/apps/details?id=com.plumelabs.air" rel="nofollow">https://play.google.com/store/apps/details?id=com.plumelabs....</a><p>We try to make the air we breathe more transparent, and we hope you find it useful!
I cycle from East London to Oxford Street every day, I found Plumelabs' data very strange: the air on the London Oxford street (the most polluted street: <a href="http://www.independent.co.uk/environment/air-pollution-in-londons-oxford-street-has-already-breached-the-legal-limit-for-the-whole-of-2015-in-9960277.html" rel="nofollow">http://www.independent.co.uk/environment/air-pollution-in-lo...</a>) is better than the Vienna's average, which is considered to one of the cleanest city in Europe (<a href="http://www.euronews.com/2015/03/31/how-does-your-city-rank-in-european-air-pollution-survey/" rel="nofollow">http://www.euronews.com/2015/03/31/how-does-your-city-rank-i...</a>). My nose tells the opposite.
I've always liked this one: <a href="http://aqicn.org/map/europe/" rel="nofollow">http://aqicn.org/map/europe/</a>
It's available for all continents.
This article has a <i>little</i> information on Plume:<p><a href="http://www.treehugger.com/health/worlds-first-global-real-time-air-pollution-map-app-launched.html" rel="nofollow">http://www.treehugger.com/health/worlds-first-global-real-ti...</a><p>"The map integrates some half a million data points each day from 11,000 environmental stations across the world,.."
How is there significantly less particulate matter and therefore less are quality in Cologne and Dortmund, which are located in a very densely populated area with a lot of traffic, than in Vienna?<p><a href="http://aqicn.org/map/europe/" rel="nofollow">http://aqicn.org/map/europe/</a> tends to only shows areas where PM2.5 is even measured as polluted, so I guess this might be inaccurate due to a lack of sensors in some areas, falsely believing they are less polluted.<p>You can easily see this by just looking at the air quality reports in Vienna: <a href="http://aqicn.org/map/europe/#@g/48.183/16.4118/12z" rel="nofollow">http://aqicn.org/map/europe/#@g/48.183/16.4118/12z</a>
I get French language interface when I click Toronto or Ottawa and English one for Montreal, with no visible button for switching. They got it backwards.
UI sucks. This is how you do it: <a href="http://aqicn.org/city/france/limousin/limoges/aine/" rel="nofollow">http://aqicn.org/city/france/limousin/limoges/aine/</a>
