Data for South Haven Meteorological Station:

LATITUDE:  42-24-05 N (Approximate)
LONGITUDE: 86-17-20 W
Site online: 21 Sep 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.

WebCam Image: See WebCam Details.

Processor:  CSI model CR10X.  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 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.
