Data for Milwaukee Meteorological Station:
LATITUDE: 43-02-44 N
LONGITUDE: 87-52-44 W
Site online: 20 Nov 2000
Special thanks to the men and women of the USCG Group Milwaukee for their technical and
financial support of this project.
LOCATION: On the Milwaukee navigation light located on the end of the north harbor inlet pier.
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 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 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 every 15 minutes. The data set
consists of six 5 minute data ensembles. Averaging and interrogation intervals and the
system program are adjustable remotely.
The webcam is located in the Cudahy tower and consists of a Sony SNC-Z20N Network Camera
