Overview of Automated Quality Assurance Runs for December 1995

Below are Mark Shafter's comments on his review of the December 1995 automated
Quality Assurance runs:
There are a few concerns for
this month's data (noted below).

PROBLEMS SITES:
---------------

BBOW PRES       December 10-11 appeared erratic; self-corrected

BUTL RELH       Numerous flags on the 2nd, flagged as bad on December 13;
                repaired December 16.

CLAY LEAF       A large number of failures during the 2nd - 11th; noted
                as bad on April 22, 1996; repaired April 23.

COOK RELH       Numerous failures on the 20th - 21st, perhaps due to low
                battery voltage.  Recovered.

NEWK SRAD       Readings dropped below -1 at night from the 6th -13th,
                and appeared low during the day.  Flags ceased on the 
                13th.  No trouble-ticket was noted, but a technician may
                have replaced the instrument on a routine visit.

Users of the data should obtain the detailed QA information from ARM
