Losing Streak: Uptick in Metro Atlanta Bad Air Days as Smog Season Winds Down
Like a marathon runner digging deep on that last mile, many Atlantans are huffing and puffing through these last days of smog season 2010. The finish line is drawing ever closer (officially September 30), but recent air quality conditions are forcing us to limp along the final stretch.
Here are the facts for Metro Atlanta:
- The region has racked up 25 ground-level exceedances for the year.
- There have been nine in September alone -- that's more September exceedances than we’ve had since 1999 – when we had 14 to close out the last month of smog season.
- We're on a streak of seven violations in the past 9 days, with another forecasted for today.
And now, some big-picture perspective on air quality:
- Ozone concentrations in Georgia and much of the United States have improved over the past few decades, even with large population increases that put more demands on energy use and vehicle travel. This improvement has been the result of state and federal regulatory controls to reduce emissions from sources like power plants, industry and automobiles, not to mention voluntary programs like those of The Clean Air Campaign.
- This year, metro Atlanta has been simmering over an extended period with temperatures that have been hotter than normal. Hot weather is a key ingredient to the formation of ground-level ozone. On top of that, the AJC reports only .14 inch of rain has fallen this month. That’s 2.91 inches below normal for the first three weeks of September. But conditions change often. Last year was much more forgiving ... and next year may be, too.
- There has never been a better time to give your car the day off, as half of all smog-forming emissions in the Atlanta region come from the tailpipes of cars. Choosing to carpool, vanpool, ride transit, telework or even bicycle and walk can make all the difference for healthier air. Sooner or later, rethinking the drive-alone commute crosses the mind of every commuter who is fed up with traffic congestion and lost money/time. So, when will you reach your tipping point?
What's a parent to do on a Code Orange day?
The Clean Air Campaign received a call this week from a concerned parent looking for guidance on whether his children should participate in outdoor activities involving physical exercise. While the best advice for parents is to consult with their child's pediatrician, there is a great reference document prepared in collaboration between The Clean Air Campaign and Children's Healthcare of Atlanta with guidelines on protecting children from air pollution. Worth a look for any parent with active children.
Full recap on smog season coming soon ...
Watch this space for a full recap of smog season 2010. The Clean Air Campaign is crunching numbers and will deliver a summary in early-October, plus a look ahead to pending changes regarding the standards by which ground-level ozone is measured.
