Unbelievable side by side images of the air quality on two consecutive days.  Did you notice it outside?

If you walked outside today (Friday, Aug. 17), you may have noticed the haze.  It was a code orange air quality, which means air pollution levels are predicted unhealthy for elderly and sensitive groups.  The air quality index (AQI) was near 100, which indicates moderate levels of air pollution.  Take a look at what it looked like over Maryland and Virigina from space via the NASA Terra satellite (image below).
