The “without stay-at-home orders” images show average monthly NO2 concentrations during March and April from 2015 through 2019, while the “during stay-at-home orders” images show average monthly concentrations in March and April 2020.

These improvements in air quality have come at a high cost, as communities grapple with the impacts of COVID-19.
