Subject:
SGP/SONDE - Pressure jump at launch
DataStreams:sgpsondewrpnC1.a0, sgpsondewrpnC1.00, sgpsondewrpnC1.a1
Description:
The difference between the sonde-reported pressure at the surface
(969.1 hPa) and the first pressure value reported after launch
(963.5) is larger than expected.  This may indicate that either
the pressure sensor was jarred at launch, that the system failed
to correctly identify the launch start time, or some other problem.

The ascent rates during the first 30 seconds of the sounding will be
incorrect as will the absolute altitudes during the sounding.
