Platform/Measurement: EBBR/AEM
        What level data: (raw,a0,a1,b1,c1 etc): a1 (5 and 30 minute)
                                                a0 (15 minute)

    What location was the data collected at: E8, Coldwater, KS

    Period of time in question
        Begin Date 08/18/95 to present

 Data should be labeled:
 ___  questionable                      ___  All data fields affected
 ___  incorrect                         ___  Only some data fields affected
 ___  wrong calibration
 _X_  others

 Discussion of Problem:

At least by August 18, 1995, the home 30 value intermittently dropped below
15, to typically a small negative number; this causes a data quality message
to be output in the site operations log as the stated acceptable range for home
30 is 15 to 34.999999.  However, no data is incorrect as a result of this
condition.

No replacement AEM is available, as the changeout kit AEMs are somewhat
different from the initial units.  I have requested site operations to
diagnose the cause of the problem on the next PM visit and hopefully correct
the problem.

I will submit another DQR or addendum when successful replacement of the
AEM is accomplished.

Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
