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

    What location was the data collected at: E13, Central Facility

    Period of time in question
        Begin Date 2/14/95   Time 1100 GMT
        End                  Time 1730 GMT

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

 Discussion of Problem:

On February 14, 1995 a frontal system deposited freezing rain in central
Oklahoma that resulted in the EBBR wind speed instrument becoming frozen in
place at the Central Facillity (E13) for part of a day.  All 5, 15, and 30
minute data values indicated below are incorrect for the period listed above.

5 minute:  wind_s, res_ws
15 minute: wind_s
30 minute: wind_s, res_ws

Other observations/measurements impacted by this problem:

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