Purple Air may have changed the reporting they do or I might have accidentally hit on a different report. Anyhow, I only reported on the particulate matter I normally do.
Odd how the 1.0 micron particulate matter concentration was so high. I now we have had fires recently, I wonder if they are the source. At least the 2.5 micron particulate matter wasn't dangerously concentrated.
