spurious data

I made a little noise about how I avoided getting sick from the fireplace smoke this morning, but tonight over on the northwest side of town, the PM2.5 reading is 120, and the oracle says "Unhealthy for sensitive groups. Increasing likelihood of respiratory symptoms in sensitive individuals, aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly." So I'd be obligated to report that Christmas will kill you, except for the fact that if you look at the oracle's data page, it becomes pretty clear that the 120 reading doesn't jibe with anything else, including previous data from the reporting site.

But that premature mortality thing gave me a bit of a start.
