Sampling the October Gunk

The meteorological transition that occurs in Salt Lake during October is quite remarkable.  Early in the month we're able to do a pretty good job of mixing out the pollution, but by the end of the month, it gets pretty stingy.

Up high in the foothills, conditions were perfect for a long ride.  The views were great, but plenty of smog could be seen in the lowlands to the west

to the north

or, alternatively, all around (it's amazing what you can do with a phone these days).

Although I normally hope the pollution scours out, I confess I'm hoping it will hang on through tomorrow.  In the morning, we will be deploying the Doppler on Wheels to examine the penetration of the lake breeze into the Tooele Valley.  We'd like the boundary layer to be good and dirty so we get good returns of the Doppler velocity and can examine the structure of the lake breeze, especially as it interacts with the surrounding topography.
