Metadata for NOAA/GLERL Milwaukee, WI Met Station

LATITUDE: 43-02-44 N
LONGITUDE: 87-52-44 W
Site online: 20 Nov 2000

LOCATION: On the Milwaukee navigation light located on the end of the north harbor inlet pier.

Special thanks to the men and women of the USCG Group Milwaukee for their technical and financial support of this project.

Site Elevation: 176.0 m above mean sea level
Anemometer Height: 12.2 m above site elevation
Air Temp Height: 9.1 m above site elevation

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

Temperature Sensor: CSI model 109 thermistor mounted in a naturally aspirated gill type radiation shield mounted on the structure railing.

Processor: CSI model CR200. This unit samples the sensors every 5 seconds and is set to an averaging interval of 2 minutes.

The wind speed shown in the "18-Hour" table and in the "5-day" graph are from the 2-minute period at the top of the hour. The data listed in the link below the "18-Hour" table (today's 2-minute data) and in the "3-hour" graph are every 2 minutes.

Wind speed is the mean wind during the 2-minute recording period. Wind gust is the maximum wind during the same 2-minute recording period. Peak wind is max wind gust during entire hour.

Power: The system is run from a 33A/hr gel cell battery which is maintained with a 20 watt Kyocer PV panel operating through a Morningstat 6 amp regulator. This battery will provide many days of stand alone operation.

Scheme: The CR10X is connected to a Raven X CDMA cell modem. The system is interrogated by a PC from Ann Arbor running the CSI Logger Net software.

The webcam is located in the Cudahy tower and consists of a Sony SNC-Z20N Network Camera

Data Line for file yyyymmdd.01t.txt: The data line is space delimited and consists of the following columns in order from left to right.

1:Station ID, Milwaukee=1
