Metadata for NOAA/GLERL South Haven, MI Met StationReturn to South Haven Met Data page
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. 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. 1:Station ID, South Haven=8 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) John Lane USDOC-NOAA-GLERL Marine Instrumentation Laboratory 9/22/04
