Hot days sometimes prompt ominous, color-coded air quality warnings that spending time outside is unhealthy. In most cities, those air quality readings are generalized from pollution measurements taken once or twice a day at a central location. Now new mapping tools and sensors are providing hyper-local, real-time snapshots of the air we breathe. Using satellite data, mobile devices, and the Internet, environmental scientists are pinpointing when and where our environment can be toxic for our health —- both indoors and out. We get a street-level snapshot of air quality in our region, and find out how the science of measuring the air we breathe is changing.
