| Description: | It appears that the operator made a typographical error when entering the
surface pressure. The file has 987.0 hPa and it probably should be 978.0
which would be consistent with the first sample provided by the radiosonde
(977.3 hPa), the surface pressures recorded for the adjacent soundings, and
the THWAPS pressure.
Because the sounding altitude is calculated assuming the surface pressure
is correct, the altitude values for the entire flight and the ascent rate
values for the first 30 seconds of the sounding will be incorrect. |
