Bonfire night particle counts

I thought that bonfire night would be interesting, and so it turned out. Above are particle counts from one of our sensors in Hull. From the looks of things most of the air particle action was in the days before bonfire night which kind of makes sense, bearing in mind that was the weekend. These numbers are not definitive (after all this is just one sensor) but I’ve seen similar changes in the readings on other sensors around the city.

You can find these readings and compare sensors on the sensor site here.
