Comments:
Daily Variables:
01 Oct 1994 to Present : Daily precipitation
Fine Resolution:
01 Oct 1994 to Present: 5 minute precipitation
Status: Two gages have been installed: a stand-alone gage with a
Valdais shield and a shelter gage. The orifice of the stand alone
gage is heated by a thermistatically controlled propane heater.
This heated gage with the very significant Valdais shielding fence
has dramatically improved our snow catch and prevented snow
bridging over the gage. The shelter gage is located on top of our
station shelter and heated through ducts from the shelter's propane
heating system. This gage has also improved catch over the more
traditionally heated raingages. However, it is protected only with an
alter wind shield and catches less than the stand-alone. A standard
raingage was operational from 18 Sep 1995 to 21 Sep 2000.

High Resolution Variables:
10 Oct 1994 to Present:
Total incoming solar radiation in megaJoules per meter squared per 15 minutes
Sensor height: 617 cm
Notes: Max solar radiation is maximum rate of incoming solar radiation as
watts per meter squared. All MAXSOLAR values were originally collected as
Langleys per minute from 10 Oct 1994 to 25 July 2007 were converted to
watts per meter squared. The time of max is accurate to the minute.
TOTSOLAR values are megaJoules per meter squared over the given time interval.
Values were originally collected as total Langleys over the given time interval from
10 Oct 1994 to 25 July 2007 but were converted to megaJoules per meter squared.
Conversions occurred in Nov 2009.
