Does anyone have a good source for tracking data on the average amounts of dustfall in the US? It feels like there's more and more dust on everything these days, on shelves, in/on cars, building up in my electronics, etc. and I'm having to deal with it more often, change filters more frequently etc. but it could easily just be the area's I'm in. I'm wondering if there's really been an increase in dust for most places or data on which places dust is more/less of a problem today.
