Sky and Ground Thermal Data for NearSys Station, 9 December 2017

The coldest ground temperature is 11 *F And the overhead stratus clouds have a temperature of 2 *F. Assuming a dry adiabatic lapse rate of 5.4 *F per 1,000 feet, the cloud base is 1,700 feet AGL.

Visibility at NearSys Station, 9 December 2017

It's a overcast day at NearSys Station and slightly foggy. The UAVSonde flight indicates that the visibility from NearSys Station is 30 miles.

Ground and Sky Thermal Observation for NearSys Station, 3 December 2017

Observations at 5:30 PM MST indicated the ground had a temperature of 18 *F and the clouds had a temperature of 0 *F. Assuming a dry adiabatic lapse rate of 5.4 *F per 1,000 feet predicts the broken stratus has a base height of 3,300 feet.

All Sky Photometer for NearSys Station, 2 December 2017

Photometer data was collected in a foggy and cloudy data. The clouds thinned, but the sky did not clear up at 1:30 PM MST.

UAVSonde for NearSys Station, 2 December 2017

UAVSONDE data was collected at 5:20 PM MST, shortly before it got dark. Here are the data.

Altitude: 2,266 feet
Temperature: 57 *F
Relative Humidity: N/A
Pressure: 934.1 mb

Altitude: 2,634 feet
Temperature: 64 *F
Relative Humidity: N/A
Pressure: 912.7 mb

I think it's pretty obvious this weather station is getting old. I plan to either make a new one or purchase a new one. A suitable replacement weather station must have a wireless remote with a range of 400 feet, at a minimum.

Visibility for NearSys Station, 2 December 2017

The UAVSonde recorded the following images from 400 feet AGL. As you can see, it was a foggy morning at 9:00 AM MST. Fortunately, the UAVSonde remained visible from the ground while recording images.

The visibility is not the same in each direction, it appears greatest towards the east at four miles.

November Weather Data for NearSys Station

The temperature chart shows we're definitely in a cooling trend since this summer. However, NearSys Station did experience some unexpected warming in November as we experienced a halt in the cooling trend during the middle of the month.

There was gap in recording data during the Thanksgiving Holiday.
November was not a dry month, but NearSys Station only experienced four rain storms.

No snow yet. Very few rain days, but two of them produced ab half inch of rain.
