AirBeam2 “Quite Accurate” According to Newly Released Performance Evaluation

During the summer and fall of 2018, South Coast Air Quality Management District (SCAQMD) evaluated the field performance of the AirBeam2 against three Federal Equivalent Method (FEM) instruments. The results were positive for the AirBeam2’s PM1 and PM2.5 measurements, with R-squared values ranging from .64 to .94, and negative for the AirBeam2s PM10 measurements, with [...]

Raspberry Pi AirBeam Data Logger

Every semester I tell my students at Medgar Evers College that to be a great research chemist, you need to be a bit of everything: a bit plumber, a bit electrician, and especially a bit coder. Environmental research chemists rely on equipment and tools that are essential to their work. The better you can use, [...]

Adding an NO2 sensor to the AirBeam

Some months ago, I took part in the Mobicitair experiment led by ATMO Auvergne Rhône Alpes, an agency that monitors air quality in southeastern France. Mobitcitair uses the AirBeam and the AirCasting platform to enable citizen scientists to take air quality measurements and crowdsource the results. I live and work in Grenoble, France, a city [...]

Can an App Make Our Cities More Breathable?

Leveraging AirBeam Data to Inform Policy Decisions

New York City recently committed to implementing a “zoned” collection system for the commercial waste sector. By dividing the city into zones and having commercial carting companies bid to service each zone, the city’s study found that the number of miles traveled by private collection vehicles will be cut by an astounding 49 to 68 [...]
