24-hour Temperature and Relative Humidity for NearSys Station, 8 December 2018

Our temperatures continue to rise (slightly) as can be seen in the temperature being higher at the reporting period than at its beginning. We're under a high pressure system that will give away to a series of cold fronts. As a result, we are expecting snow sometime Monday. I suspect the snow won't last in the valley with these higher temperatures.

All Sky LED Photometer for NearSys Station, 2 December 2018

We had a small amount of rain and snow at NearSys Station this weekend. The precip prevented me from placing the photometers outside until noon today. So the extent of the data is more limited this weekend.

We have a break in the clouds that can also be seen in the CloudCam video posted to my YouTube channel (it will get posted tomorrow).

Paul's SciTrek: Utah State University Eastern Prehistoric Museum

Prehistoric Museum 155 East Main Street, Price, Utah

On November 17th, I visited the Prehistoric Museum in Price, Utah. The museum is open Monday through Saturday from 9:00 AM to 5:00 PM. Admissions are listed as follows,

Ages 2 - 12: $3
Adult: $6
Senior: $5
Military: $5
Family: $17
Military Family: $14

Parking is free and the museum does give tours with advanced notice. The museum in Price is one of the five accredited museums in Utah and is your one-stop destination to discover eastern Utah's prehistory.

The museum is two stories tall and consists of two wings. One wing is dedicated to dinosaurs (paleontology) while the other wing is dedicated to the Fremont People (archaeology). One corner of the paleontology wing is set aside for children to play through hands-on educational activities.

Older than a dinosaur, a Dimetrodon. This animal's descendants lead to mammals and not reptiles.

Stegosaurus, notice the bony bib protecting its neck.

Chasmosaurus belli, a 73 million year-old armored dinosaur.

The Utahraptor greeting you at the museum.
The large diorama in the archaeology wing. Human versus Mastodon.

A replica petroglyph of the Fremont People.

Some of the pottery on display.

Everyone's favorite, a Saber-toothed Cat (note, this is not a tiger).

A Short-faced Bear. These bears where 50% larger than modern bears and the largest predatory land mammals ever in North America.


A dire wolf. These big wolves were living in North America when humans crossed the Bering Strait.

UAVSonde Data for NearSys Station, 11 November 2018

The UAVSonde was launched at 14:00 MST today to collect data. Images indicate the visibility is at least 50 miles. The tilt in the images, especially east-looking one indicates there was a lot of wind at Flight Level 4. The upper troposphere is becoming more humid on account of the increasing amount cirrus clouds and the longer contrails present.

Conditions at the surface were,
Temperature: 54.5 degrees
Relative Humidity: 24.6%

At Flight Level 4:
Temperature: 53.2 degrees
Relative Humidity: 22.4%

24-hour Temperature and Relative Humidity for NearSys Station, 10 November 2018

In the chart below, it can be seen where the sun shield for the datalogger was blown over between noon and 4:00 PM. This means the datalogger was exposed to direct sunlight During this time. During this time frame, NearSys Station experienced partly cloudy skies which gave rise to the fluctuations observed in the temperature.

24-hour All-sky LED Photometer for NearSys Station, 10 November 2018

The LED Photometer required two repairs before it could start collecting data again. So there have been no reports since May. I finally had time and inclination inclination to troubleshoot and repair it. Below is the proper output from the working photometer. It can be seen that between 2:00 and 3:30 PM MST NearSys Station experienced partially cloudy skies.

Unlike past reports, the photometer now includes red data. However, the photometer still operates from a four "AAA" alkaline cell pack. So I plan to switch it and the UV-B Photometer over to a 5V rechargeable battery pack. Then perhaps place them inside the weather-proof can I partially 3D designed and built. Then assemble the GPS recorder for the buoy???

24-hour LED Photometer for NearSys Station, 5 November 2018

The LED Photometer is finally working again. But I still need to find out what's going on with the red LED, it's not producing an output. Perhaps it's a bad trace.

From the chart below, it's apparent that we had partly cloudy skies.
