Air quality in Hayes Valley under stay-at-home

Usually a hub of freeway ramp traffic, data shows a central neighborhood now approaches San Francisco’s average.

So much of the outdoors has changed for the better since the gloom of pandemic arrived: quieter streets, more birds. The air quality in Hayes Valley has been so notcieably good since the city’s shelter-in-place order went into effect back in mid-March that I wanted to see how much better it really was.
