Metadata for NOAA/GLERL Milwaukee, WI Met Station

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 107 thermistor mounted in a naturally aspirated gill type
radiation shield mounted on the structure railing.

Processor:  CSI model CR10X.  This units samples the sensors every 5 seconds and is set to
an averaging interval of 5 minutes.

Power:  The system is run from a 12A/hr gel cell battery which is maintained with an 11 watt
Unisolar PV panel operating through a Solar Electric CREG5 regulator. This battery will
provide a day of stand alone operation.

Scheme:  The CR10X is connected to a Campbell Scientific COM 100 communications package. This
consists of a modem and a Motorola analog cellular telephone module.  The system is
interrogated by a PC from Ann Arbor running the CSI PC208W software and a modem every half
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: The data line is space delimited and consists of the following columns in order from 
left to right.

1:Station ID, Milwaukee=1
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)

-99 = missing/bad data
