Subject:
SGP/SONDE/C1 - Incorrect absolute pressure
DataStreams:sgpsondewrpnC1.a0, sgpsondewndcalcC1.c1, sgpsondewrpnC1.00, sgpsondewrpnC1.a1
Description:
The surface pressure (983.5 hPa) reported by this radiosonde (sn 94315713)
is substantially higher than that reported by the THWAPS (~977) or by the
sondes used in the previous and following soundings (976.6, 977.3).  This
may be a calibration problem or a mechanic problem on launch.  The pressure
values reported in the remainder of the sounding are consistent with the
reported surface pressure, so the altitudes should be correct.  The
absolute pressure values may be high by about 5 hPa.
