Subject:
B4 - Pressure jump at launch
DataStreams:sgpsondewrpnB4.a1
Description:
The difference between the first pressure value recorded by the sonde
after launch (936.6) and the value for surface pressure recorded by the
operator (944.9) is greater than normally expected.  This may be due to
physical jarring of the sonde at launch, to misidentification of the
launch time by the system, or some other cause.  The altitude values for
this sounding will be incorrect as will be the ascent rate values during
the first 30 seconds of the flight.
