I am David, one of Plume Labs&#x27; 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 =&gt; <a href="https:&#x2F;&#x2F;itunes.apple.com&#x2F;en&#x2F;app&#x2F;plume-air-report-pollution&#x2F;id950289243?mt=8" rel="nofollow">https:&#x2F;&#x2F;itunes.apple.com&#x2F;en&#x2F;app&#x2F;plume-air-report-pollution&#x2F;i...</a><p>Android =&gt; <a href="https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=com.plumelabs.air" rel="nofollow">https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=com.plumelabs....</a><p>We try to make the air we breathe more transparent, and we hope you find it useful!
