Subject:
SGP/SONDE - Incorrect surface pressure
DataStreams:sgpsondewrpnB1.a1, sgpsondewrpnB1.00, sgpsondewrpnB1.a0
Description:
The operator entered the THWAPS surface pressure (965.6) rather
than the sonde surface pressure (963.8) into the sounding file.
This will result in inaccurate ascent rates during the first
30 seconds of the sounding and inaccurate absolute altitudes
throughout.
