Golden Sunrise

I have never seen a sunrise like this before. When I stepped off the train in Salt Lake at 7:20 AM, the sky was on fire. The light was like pure gold and it filled the sky. What made it so gold? Partially because of blowing dust. Wind's have been quite strong from the south.

Winds throughout the valley were strong from the south all night long. The south wind and associated mixing caused the temperatures in the area to stay warm throughout the night. At MTMET the temperatures never fell below 60 last night. Very unusual for the last week of November.

The PM 2.5 concentration took a spike at the same time as sunrise. The dust in the air scatters the light, and gave us the pretty sunrise.
