D.C. Air Quality 2008 vs. 2009

D.C. Air Quality 2008 vs. 2009, posted by Chris Naille, Meteorologist.

  • More Code Red Days in 2008 than in 2009: “Much of the summer thus far has been noted by slightly cooler than average temperatures coupled with an active weather pattern that has yielded nearly daily chances of showers and storms. Compared to 2008 when we transitioned into a more “typical” D.C. summer pattern nearly on cue. Last years “typical” pattern consisted of hot and humid strings of days with a much lower daily opportunity for cleansing rains.”
