How air pollution changed during COVID-19 in Park City, Utah
Throughout the pandemic, air sensors watched during lockdowns as air pollution fell in residential and commercial areas, and then as pollution rose again with reopenings. The changing levels, the researchers found, which behaved differently in residential and commercial parts of the city, show where pollution is coming from and how it might change in the future under different policies.

Low-Cost Home Air Quality Monitors Prove Useful for Wildfire Smoke
Published recently in the journal Sensors, a new study by Berkeley Lab air quality scientists tested four models of low-cost air quality monitors during actual wildfire pollution events and found that their readings of PM2.5 – or particulate matter under 2.5 microns, which has been linked to respiratory and cardiovascular issues – were consistently higher than the reference monitor used by the regulatory agencies; however, since each monitor had a relatively consistent response to the smoke, it is possible to use the readings to estimate true PM2.5 levels. Overall, the researchers concluded that the monitors can provide actionable information.
