Google offers new treasure trove of air quality data to researchers

By Jill T Frey

Google has employed its network of street-view vehicles to also measure street-level air quality in recent years, through an initiative it calls “Project Air View.” Today, it’s making available to scientists and researcher organizations more of the resulting data from that ongoing initiative. The company is releasing an updated version of its air quality data set that includes information collected with partner Aclima’s environmental sensors gathered between 2017 and 2018.

The combined data cache includes info from the SF Bay and San Joaquin Valley area, originally starting in 2016, along with the additional two years’ worth of data for those areas as well as for other parts of California, and other major cities, including Houston, Salt Lake City, Copenhagen, London and Amsterdam.

Nor can hardware solve this problem. But smart hardware can at least help.

For about a month I’ve been road-testing a wi-fi connected air purifier made by Swedish company, Blueair. It uses an Hepa filtration system combined with integrated air quality sensors to provide real-time in-app feedback which can be reassuring or alert you to unseen problems.
