The map also shows the air quality information from purpleair, a low-cost sensor network that can give you ultra local conditions.
To add this air quality layer to your map, you need to click the button in the upper right corner of the mobile screen, and then select air quality under map details. Purpleair information can also be used on nest monitors and speakers.
