Sensor Data:

Anemometer:  R. M. Young Wind Monitor model 5103.
Location:  At the top of the old Coast Guard communications tower at about 80'.

Temperature and RH sensor:  R.M. Young model 41372VC 
Location:  This unit is installed in a R.M. Young model 41002P multiplate radiation shield
and located at about the 20' level on the old Coast Guard communications tower.

Barometric Pressure Sensor:  R. M. Young model 61201 and an attached model 61002 remote
barometric pressure port.
Location:  Co-located with the Temp/RH sensor above.

PAR sensor:  Biospherical Instruments model QSR-240.  Located on the roof at the north end of
the LMFS garage building.
Spherical sensor.  On 1 July, 2004, the output units changed from quantum/cm2/sec X E15 to
uE/cm2/s; max value about 0.32. On May 18, 2005, the output units changed from uE/cm2/s to
uE/m2/sec; max value about 3200.

Processor:  CSI model CR10.  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 commercial AC power supply which is backed up by a 1KVA UPS.

WebCam Image: The LMFS webcam array consists of 4 Panasonic WV-CP234 CCTV cameras.  These are
connected to an Axis 2400 video server which is present on the LMFS LAN.  The system is set
to FTP images to our Ann Arbor office every 5 minutes. The resolution of these images is
704x480.

Scheme:  The CR10 is connected (through an SC-32A serial adapter) to a Lantronix UDS-10
serial port server. The system is connected to an ethernet LAN at LMFS and is interrogated by
a PC from Ann Arbor running the CSI PC208W software very 15 minutes.  The data set consists
of three 5 minute data ensembles.  Averaging, interrogation intervals and the system program
are adjustable remotely.  The system data rate is set to 9600 baud.  As of this writing the
LMFS system has been integrated into a regional real time meteorological network.

Data Line: The data line is space delimited and consists of the following columns in order from 
left to right.

1:Station ID, Muskegon=5
2:Year
3:Day of Year
4:Time, UTC
5:Average air temperature, Deg C
6:Scaler average wind speed, m/s
7:Wind Speed maximum, m/s
8:Unit vector average wind direction, degrees from (0=north, 90=east)
9:Average relative humidity, %
10:Average station pressure, millibars
11:Average PAR, (Photosynthetically active radiation), uE/m2/s
