As of this evening, the pyranometer data is now online. Here is the link to The Weather Underground site. The site ID is KPAPORTM11.

First Day of Pyranometer Operation
In a previous post, I talked about installing a new pyranometer to my weather station. Below is a graph of today’s solar radiation flux in W/m^2.
The graph clearly shows when the instrument was in shade (7:30 – 9:30 AM EST). Maximum value was after noon due to the fact that the longitude is about 3 deg west of the 75th meridian and because the equation of time for today is 3 minutes. The maximum solar elevation angle was about 28 deg. The optical depth of the atmosphere is significantly higher at such a low angle than if the sun was at zenith.

Pyranometer
Today, I installed a new weather instrument, for 2017 and beyond, to my personal weather station (PWS). I installed a pyranometer to measure the solar radiation flux density (W/m**2). The data from the instrument will be sampled every 30 minutes, along with the other parameters that are already being logged.
I have been told that the State College region is cloudier than most. Now I can measure just how “gray” the environment is here.
What, Me Worry?
It took a little over two months to not worry about what day of the week it is each day. It’s now necessary for me to consult a calendar of some sort to learn the date and day of the week. My only requirement is to remember to put out the trash and recyclables on Friday morning.
Scotty Alarm Clock
Since I retired, and except for mornings when I have an early appointment, I have rarely used my alarm clock. Instead, one of our Scottish Terriers, Tillie, provides me with a wakeup bark. Usually, between 6:30 and 7:00 AM, she’ll let me know it’s time to get up. She’ll also get more insistent if I ignore her, or if she feels that I am taking too long. Then she’ll whimper in a classic appeal to emotion. Then it’s time for our morning walk and breakfast.
Scotty Cramp
Until yesterday afternoon, my wife and I had not heard of a genetic condition specific to Scottish Terriers. Our Scotties, Toby Two and Tillie, normally very active, became listless after prolonged exercise in our backyard. We immediately took them to the vet and learned about their ailment.
“Scotty Cramp” is a hereditary neuromuscular disorder characterized by periodic cramps. It is seen in Scottish Terriers, especially those less than one year of age. As we observed, the condition’s appearance was quite startling, an its onset was rapid. However, it does not usually represent a serious health problem or cause pain.
Episodes of Scottie Cramp typically first manifest in young dogs or puppies. Our Scotties are now 15 months old. Symptoms occur during or shortly after periods of intense excitement, stress, or exercise and may include any of the following:
- Stiff hind limbs that appear cramped
- Awkward, marching movements
- Shortness of breath
- Sudden collapse
- Facial muscle contractions
- Contraction of facial muscles
- Arching of lumbar spine
An episode of Scottie Cramp can last up to thirty minutes, with varying levels of severity. As we observed, its onset occurred after the stress of moving to a new home and after increased activity. Although it is inherited, some experts believe Scotty Cramp to be the result of a disorder in serotonin metabolism within the dog’s central nervous system.
Unfortunately, there is no specific treatment available at this time. However, behavioral modification and/or environmental changes have been shown and are recommended to eliminate triggers which may cause the onset of symptoms.
Mild sedatives, such as diazepam, may be useful if behaviors are difficult to modify or in advance of a planned event that may be stressful. Also, Vitamin E is thought to be beneficial in reducing the likelihood of an attack, although it does not appear to impact the severity of the cramping.
After 24 hours of resting and reduced activity, our dogs have returned to their normal active selves.
Indian Summer
Some would say that our area is now in the midst of Indian Summer (is that politically correct?). Yesterday morning, the temperature in Stormstown fell just below 32 deg F (31.6 F at 6:00 AM EDT), the first recorded freezing temperature of the season. There was frost on the lawns as seen below:
As the sun rose, the frost that was in full sunlight dissipated, while the frost in shadow remained.
The foliage has some color. However, it is not expected to be spectacular this year as the region has suffered a drought over the summer.
It is definitely jacket weather here, nonetheless.
Tropical Storm Matthew
Tropical Storm Matthew formed today. It is forecast to become a hurricane this Friday.
What is unusual is that the forecast track has the system making a hard right turn to the north sometime this weekend. Most of the models are in agreement to that forecast.
However, the two main models, GFS and ECMWF, disagree on where it will track a week from now. An earlier run of the GFS had it going up Chesapeake Bay next Thursday. The ECMWF has it moving slower with a possible landfall in southern Florida, so this should be watched carefully in the coming days.
BloomSky Weather Station
Over the weekend, I installed a BloomSky weather station at my home in Stormstown. The installation was simple. The only tool required was a Phillips screwdriver.
First, the mount was simply clamped to the backyard fence. Then a mounting plate for the solar panel was screwed onto the mount. The solar panel simply clipped to the plate. Before mounting the sensors, it had to be configured for the WiFi by using the iOS app. This was an easy process after plugging it in using the supplied AC adapter.
Lastly, the weather station itself only had to be dropped in place into the mount, and then plug in the solar panel. The only issue was the the air pressure didn’t report at first. This was resolved by unplugging the solar array and cycling the power from the internal battery. Then plug the solar array back in.
