LMFS Met station information sheet:

LATITUDE:  43-13-40 N
LONGITUDE: 86-20-20 W
LOCATION:  Coast Guard communications tower, Muskegon, MI
Site online 14 Oct 1998
Lake level above sea level:  176.2m (578')
Base of tower above lake level: 3.1m (10')

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.

Data conversion:  

Data is acquired and processed by an R.M. Young model 26700 programmable 
translator.

Data Transmission:

Data is transmitted via FTP to Ann Arbor as an ensemble of 15 one minute data 
averages.  Time stamps on the data sets are generated by a processing PC which is
automatically coordinated to NIST on a daily basis.  The composition of the individual 
data line follows:

Note: Barometric Pressure values were corrected to sea level (offset = 22mb, h=185.3m, 
T=53F) at 1855 UTC, 12/15/1999.

Note: The 22mb offset to barometric pressure was removed at 1845 UTC, 03/16/2000. The 
reported pressure is now station pressure, from which sea level pressure is calculated.
