Metadata for NOAA/GLERL Toledo Light #2 Met Station

Data for Toledo Light #2 Meteorological 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.

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: 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)
2:Year
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)
