Station Located at 41° 31' 12" N and 75° 32' 50" W @ 972 feet.

The Jermyn Pa weather station consists of 4 major components:

The ISS pictured below measures temperature, humidity, rain, solar and ultraviolet radiation. Each of these sensors transmits its data to the display console every 2.5 seconds via a 2.4 ghz radio. The ISS is mounted on a steel pole 6 feet above grass. The round white louvers at the base contain the temperature and humidity sensors. The large black cylindrical section is the rain gauge. To the rear of the rain gauge are the solar and UV sensors. The solar panel provides the necessary power to operate the station. During nighttime hours or very cloudy days, an internal 3 volt lithium battery does the job.

Pictured next is the anemometer/wind vane. Like the ISS, it also transmits its data to the console every 2.5 seconds. Normally the anemometer is co-located with the ISS, but nearby trees prevented accurate wind measurement. A few months after installation, my son and I moved it to a nearby roof. The anemometer/wind vane also has it's own solar panel and radio.

Next is the indoor display console. Its 2.4 ghz receiver collects data from the ISS and wind instruments. The picture below was taken with the internal yellow backlight on.

The console is connected to a PC via a USB link. The software has been collecting and storing weather data once every minute since August 29 2005. The PC also sends html pages I constructed as templates to this web server every 10 minutes via ftp. Here is a screen shot of the real-time monitor screen on the PC.

Weather observations from this station are also used by NOAA's Mesonet site, the Citizen Weather Observer Program and the Weather Underground.
