Data for South Haven Meteorological Station:

LATITUDE:  42-24-05 N  (Approximate)
LONGITUDE: 86-17-20 W
Site online: 9/21/2004 

Special thanks to the USCG 9th District and USCG ATON Group Muskegon for use of the 
navigation structure.

Location: On the South Haven light located on the end of the south harbor inlet pier.

Site Elevation: 176.0 m above mean sea level
Anemometer Height: 16.8 m above site elevation
Air Temp Height: 13.7 m above site elevation


Wind Sensor:  R.M. Young model 5103 Wind monitor mounted on the structure railing.

Temperature Sensor:  CSI model 107 thermistor mounted in a naturally aspirated gill  type
radiation shield mounted on the anemometer mast.

Processor:  CSI model CR10X.  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 12A/hr gel cell battery which is charged from the AC line.

Scheme:  The CR10X is connected to a Campbell Scientific COM 200 modem and a standard
Motorola cellular analog "bag Phone" with an RJ-45 adapter. The system is interrogated  by a
PC from Ann Arbor running the CSI Logger Net software and a telephone modem every hour.   
The data set consists of three 5 minute data ensembles.  Averaging and interrogation 
intervals and the system program are adjustable remotely.  The system data rate is set  to
1200 baud.

Data Line: The data line is comma delimited and consists of the following in order  from left
to right.
