Canada Wildfire Smoke Reaches Stormstown

Afternoon at Stormstown, PA on Wednesday, June 7, 2023

On Wednesday, June 7, 2023, smoke from several major wildfires in Canada drifted into the central Pennsylvania region. The air quality in the area became unhealthy as a result.

This is a graph of air quality parameters collected during the week of June 7. A Davis AirLink sensor at my home collected the data. The wood smoke adjustment was enabled.

The graph shows that the general air quality index (AQI), the index for particulates that are 10 micrometers and smaller (PMI 10) was quite high, and particulates of 2.5 micrometers and smaller (PMI 2.5). In fact, the overall AQI was in the red or unhealthy range, nearly at the purple or very unhealthy level. Particulates of 1 micrometer or smaller (PMI 1) were in the moderate range.

More information can be found in the EPA AQI guide.
