Subject:
Questionable surface pressure
DataStreams:sgpsondewrpnB1.a1, sgpsondewrpnB1.a0
Description:
The surface pressure for this sounding was entered by the operator as 967.1 hPa. The first 
pressure value reported by the sonde is 954.4 hPa. The surface pressure at 02:30 was 
950.3 but at 23:30 (8/4) it was 962.5 (sonde 960.7). It appears that the either the operator 
mistakenly entered the 967.1 rather  than 957.1 and/or that the pressure sensor may have 
jumped after launch. In any event, the difference between the surface sample and the 
first sonde sample exceeds our criterion for flagging.

Note that this will affect the altitude calculation throughout the sounding.
