Particulate matter 2.5 micron was really bad this week. Other diameters were fine. I see that I can download data for other sized particles. So now need to update my spreadsheet.

Foggy. We had poor visibility this weekend. When I launched the UAVSonde, the visibility had only increased to 30 miles.

Air Quality for NearSys Station, 17 - 23 January 2020

The air quality was fine earlier this week (except for a spike), but went way south towards the end. Probably from people using their fire places. The most worrisome particular matter is those with a diameter of 2.5 microns.

At last, a week of good air. What spikes we experienced were brief and minor.

All-Sky Photometer for NearSys Station, 19 January 2020

We had some haze today. But since there were no clouds, the sky brightness didn't drop out. At the same time, the sky never got very bright for a cloudless day. We experienced a thin layer of cirrus clouds only.

Visibility for NearSys Station, 19 January 2020

We're under a minor inversion that keeps a thin layer of haze close to the ground. Through the haze, visibility is around 15 miles. Above it, the visibility is in excess of 50 miles.
