Yeah the past few Summers were brutal. Seems the air quality has been better as well.
Based on data collected between March and September 2021, there were 23 days when ozone concentrations in New England reached unhealthy levels. By contrast, in 2020 there were 18 unhealthy ozone days in New England.
If I'm reading the data correctly there's only been one this year on the 24th of July.
