During the night colder, cleaner air filters downslope and replaces the dirty air at the sensor sites. Perhaps, simply pushing the dirty air up above the sensors. When day heating occurs the cooler air at the surface warms and the dirty air "falls" back to sensor level. Can those sondes record PM2.5 data with elevation?Bubbanoreply@blogger.comtag:blogger.com,1999:blog-6168620747792092240.post-55197197504573202582015-01-09T11:26:24.921-07:002015-01-09T11:26:24.921-07:00Seems to be very complicated physics driving mecha...Seems to be very complicated physics driving mechanisms for spatial and temporal variations in particulate matter concentrations. I wonder if a large contributing factor to decreased concentrations during night time is due to entrainment of cleaner air from along the down slope of the benches driven by radiational cooling in the benches above the inversion? Closer to the lake, perhaps there is turbulence associated with a land breeze during the night that causes more mixing with air over the lake? This is very interesting stuff.Lisahttps://www.blogger.com/profile/15180331785357345922noreply@blogger.com
