Metadata for NOAA/GLERL Toledo Light #2 Met Station


LATITUDE: 41-49-32 N
LONGITUDE: 83-11-37 W
Site online: 31 Aug 2004

Location: On navigation light #2 on the approach to Toledo Harbor

Site Elevation: 173.5 m above mean sea level
Anemometer Height: 14.9 m above site elevation
Air Temp Height: 14.0 m above site elevation

Wind Sensor: R.M. Young model 05103 Wind monitor mounted on the top of the structure.

Temperature Sensor: CSI model 109 thermistor mounted in a naturally aspirated gill type radiation shield mounted on the anemometer mast.

Processor: CSI model CR 200. This units samples the sensors every 5 seconds and is set to an averaging interval of 5 minutes. For each 5-minute interval, a mean and max (gust) wind speed are reported. The peak wind is the max of all of the gusts during the hour.

The wind speed shown in the "18-Hour" table and in the "5-day" graph are from the 5-minute period at the top of the hour. The data listed in the link below the "18-Hour" table (today's 5-minute data) and in the "3-hour" graph are every 5 minutes.

Power: The system is run from a 110A/hr gel cell battery bank which is maintained with a 120 watt Kyocera PV panel operating through a Morningstar solar regulator. The met system is part of a larger system intended for realtime environmental sensing which will eventually encompass a web cam and other sensors.

Web Cam: The webcam is a Toshiba model IK-WB15A. The camera is pointing southeast.

Scheme: The CR200 is connected through a port server to a UHF radio modem which communicates with a base station in the Toledo area. It is interrogated from Ann Arbor via the internet.

The data set consists of 5 minute data ensembles. Averaging and interrogation intervals and the system program are adjustable remotely.

Data Line for file yyyymmdd.12t.txt: The data line is space delimited and consists of the following columns in order from left to right.

1:Station ID, 12 (Toledo Light #2)

3:Day of Year
4:Time, UTC
5:Average air temperature, Deg C
6:Wind Speed average m/s
7:Wind Speed maximum, m/s
8:Wind Direction, average, degrees from (0=north, 90=east)
