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 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 comma delimited and consists of the following in order from left to right. Station ID, Milwaukee=1 Year Julian Day Time, GMT Voltage measured at CR10X Voltage, PV panel. Panel (equipment compartment) Temperature, Deg C Average air temperature, Deg C Air temperature standard deviation, Deg C Wind Speed minimum, m/s Wind Speed maximum, m/s Wind Speed, standard deviation m/s Wind Speed, scalar average, m/s Wind Direction, unit vector average, degrees from (0=north, 90=east) Wind Direction, standard deviation, degrees. -99 = missing/bad data John Lane USDOC-NOAA-GLERL Marine Instrumentation Laboratory 5/11/01
