Discussion of Problem:
It appears that the site operator made a keyboard mistake when entering the
surface pressure for the subject sounding. The pressure was entered as 999.6
and the first pressure value reported by the radiosonde was 989.3 hPa. The
operators meteorological observaation log shows a sea-level pressure of 992.3
hPa at 1700.
The incorrect pressure value will affect the altitude values reported during
the sounding and the ascent rate values during the first 30 seconds of the
sounding.
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. |
