NSA/PWS/C1 - Calibration drift
DataStreams:nsapwsC1.a1
Description:
The calibration of the sensor drifted downwards slightly more than 3% during the more than 
two years in between calibrations.  The drift had no significant impact on the data 
produced.  Note: the period of this DQR extends back prior to 20000503 when the datastream 
was named nsapwsC1.a0.

NSA/ORG/C1 - Optical Rain Gauge incorrect at very low temperatures
DataStreams:nsaorgC1.a1, nsaorgC1.b1
Description:
The ORG reports precipitation rates that are more than 2 orders of
magnitude greater than those reported by the present weather sensor
when the temperature drops below -25 C.  Examples of this error can
be seen in the data for January 11-13, 2000, however the problem is
not isolated to these days.

A drift occurs when temps are in the range of -25 C to -40 C that
exceeds the maximum drift allowed/expected for the instrument.  The
drift is then reported as precipitation.

The manufacturer of the instrument has not yet been able to identify a
fix for the problem.
