I’m working on getting a grant from a local org to purchase a PurpleAir sensor to collect air quality data in our neighborhood, which is close to an asphalt plant and railroad tracks. My question is: will the air quality on the 5th floor differ greatly from ground level?
My apartment is on the 5th floor, overlooking a local trail and then the tracks. I’ve read differing things about air mixing. I just don’t want to waste the grant by placing it somewhere that won’t be representative of the neighborhood.
