A remarkable thing about covid-19, the coronavirus-caused disease spreading around the globe, is…, “Nitrogen dioxide is produced by fossil fuel burning and therefore often used as an urban pollution tracer,” Barbara Dix, an atmospheric researcher at the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder, told Earther in an email. The U.S.-Canadian border, like its southern counterpart, is also closed outside of essential services and trade. Ditto for Boston, Philadelphia, Baltimore, and Washington, which normally form a daisy chain of pollution along Interstate 95.

There are also natural sources of nitrogen dioxide that can affect readings. While the data is a bit noisy, nitrogen dioxide emissions in Houston, a hot spot for the petrochemical industry, appear to have declined.
