Data for Toledo Light #2 Meteorological Station:

LATITUDE:  41-49-32 N
LONGITUDE: 83-11-37 W
Site online: 9/27/04 

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.

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 comma delimited and consists of the following in order from left to right.
