Our Air Quality Index spreadsheet has been updated to include data through November.
Highlights from Mark Barker of the Blue Ridge Environmental Defense League:
- None of the days in November were in the Top Ten highest days for ozone or PM 2.5 for 2015.
- Only 1 yellow day in November. That was for PM 2.5 and it was at AQI of 51, just barely in the yellow.
- With one month to go, 2015 is looking like it will be an average year for Rke Valley AQI: roughly over 30 yellow AQI days.
- So far in 2015, 298 green days and 36 yellow days. This is comparable to recent years: 2014: 329 Green AQI days, 36 Yellow days. 2013: 344 Green AQI days, 21 Yellow (note: There was no PM 2.5 monitor from March 8 – July 3, 2013). 2012: 321 Green AQI days, 38 Yellow days, 1 Orange day, and 6 no data days.
