Subject:
Pressure jump at launch
DataStreams:sgpsondewrpnB4.a0, sgpsondewrpnB4.a1
Description:
The difference between the first pressure value reported by the sonde after
launch (942.8) and the surface pressure (949.2) is greater than expected.
This may indicate that the sonde was jarred at launch or that the system
failed to identify the start time properly.  The absolute altitudes for
this sounding will be questionable as will be the ascent rate during the
first 30 s.
