Metadata for NOAA/GLERL South Haven, MI Met Station

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

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

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

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.

Data Line for file yyyymmdd.08t.txt: The data line is space delimited and consists of the following columns in order from left to right.
