Discussion of Problem:
The BF operator noticed that the weather measure set used to provide the
surface values for the soundings was incorrectly set to output wind speed
in knots rather than m/s from 3/17 to (and including) 3/24. As a result,
the value of the surface wind speed in the subject soundings is approximately
twice the correct value (conversion of knots to meters/sec).
Because the surface wind speed is not used in any subsequent calculation
by the system, this should be a very low impact problem.
Other observations/measurements impacted by this problem:
None
Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
Flag data. |
