Air Quality for NearSys Station, 10 -16 January 2020

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

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.

Visibility for NearSys Station, 14 January 2020

Overcast day, but the visibility did reach 50 miles towards the east where the peaks of the Boise Mountains rose above the cloud tops. To the south, peaks 30 miles away were not visible as the peaks of the Owyhee Mountains didn't clear the clouds.

Most of the snow from the previous day had melted by this afternoon. 




East - the tops of the Boise Mountains are visible

Air Quality for NearSys Station, 3 - 10 January 2020

We had good air quality this week except for a bit of time on the 4th and 8th. Otherwise, the air quality was in the green all week. One reason was because of our wind. An inversion was unable to establish itself.

House Finch at the Bird Feeder

I thought a photograph of a bird at one of my feeders would be perfect on a snowy morning. So here it is.

House Finch eating sunflower seeds on the morning of January 5th.
