Weekend Edition: Moderate air quality in the Southeast and some ozone picking up

The fires in the southeast continue to bring isolated areas of code orange to the region and make the overall average in the moderate range. See the individual station data on the left and the average on the right.

Ozone is peaking up into the moderate range now that spring is coming and the solar elevation angle is increasing. We are still a few weeks away from the "unofficial" start to ozone season.

Out over the Pacific there is a lonely wisp of high altitude sulfate which is probably the residual of the Kelud volcanic eruption last month (image below... layer at 25 km is probably volcanic). This image is from 3/14.
