First-of-its-kindtechnologyissupportingefforts to cutair and climatepollutionfor people and the planet. The air we breatheispolluted by many differentsourcesfrom cars and trucks to household energyuse. Today, air pollutionis the 2ndleadingriskfactor fordeath around the world.Pollution respectsnoboundariesand is moved aroundcommunitiesbyshiftingwind and weather patterns, makingithard to identify the sources. Andwhenwe don’tknow the source of pollution, we can’taddress it. PARTNER PERSPECTIVE Air Tracker has provento bea valuableassetto our environmental management—especially in emergency responseand in the rapid identification ofcommunitiesimpactedby criticalpollution episodes—strengthening ourmanagement and response capabilities. Air Tracker is changing that. EDF and partnerscreatedthisadvancedonline toolto help userslearn more about theairthey’re breathing andallow them to pinpoint where it’s coming from.AirTrackerrunson real-time, trusted scientific models—combining air pollution and weather forecastingdata—tohelpcommunities and localgovernmentsvisualizepotential sources ofemissions,andget theinformation needed to takeactions that reduce emissions and protect thepublic’s health.

Theregulatoryairmonitor in the arearegularlyrecords PM2.5 levels that are much higher thanmonitorsin other parts of thecity. The community wanted to know what sources might contributeto these elevated pollution levels.Air Trackerwas usedtolook at specific days of elevatedpollution and founddifferent industrial sources impactingair qualityat different times.

By pulling in data from regulatory monitorsas well as low-cost sensors,communitiescan gain abetter sense of the levels of pollutionin theirareasandsources ofthatpollution. With the ability toallow users tocreate time-stamped maps, communities can share specific time and locationinformation with government officials.
