In our continuing effort to provide the news on citizen science air pollution monitoring tools and techniques, we share two articles this morning – the first an update on AirCasting, developed by the nonprofit EJ organization HabitatMap, and the second an article on Elm, a new commercial real-time air quality monitor developed by PerkinElmer, and being marketed to cities for neighborhood-level monitoring.

We reported on a third, and perhaps the most mature real-time inexpensive monitoring system, the Air Quality Egg, a couple of weeks ago. The Air Quality Egg is an open source solution currently being rolled out on a big scale in Louisville, Kentucky. We’ll give you an update on that project soon.
