 Discussion of Problem:

The surface pressure for this sounding was entered by the operator as 1016.1
hPa. The first pressure value reported by the sonde is 988.3 hPa. The surface
pressure at 11:29 was 987.6 and at 17:32 was 988.3.  It appears that the
operator entered the sea-level pressure rather than the station pressure.

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

 Discussion of Problem:

The surface pressure for this sounding was entered by the operator as 996.1
hPa. The first pressure value reported by the sonde is 964.2 hPa. The surface
pressure at 11:30 was 972.0 and at 14:30 was 973.5.  It appears that the
operator entered the sea-level pressure rather than the station pressure.
The SMOS pressure during the period is in the 960-970 range.

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

 Discussion of Problem:

The surface pressure for this sounding was entered by the operator as 987.7
hPa. The first pressure value reported by the sonde is 976.1 hPa.  The
operator transposed the correct surface pressure 978.7 when entering the
data.

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

 Discussion of Problem:

The surface pressure for this sounding was entered by the operator as 976.1
hPa.  Analysis of the raw data file suggests that the actual surface pressure
at time of launch was 967.1 hPa.  It appears that the operator transposed 
the correct surface pressure from 967.1 to 976.1 when entering the data.

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

Bad pressure values CF sounding 970704:0525
DataStreams:sgpsondewrpnC1.a1
Description:
The pressure values and hence altitude values are most likely incorrect
in this sounding.  It also appears that an incorrect surface pressure
value was entered by the operator.  The surface pressure value in
the data (986.8) is somewhat higher than the surface pressures for the
neighboring soundings and higher than recorded in the raw data collected
before launch (~978 hPa).  The first pressure value recorded by the
sonde after launch is 884.8 hPa.  Analysis of the absolutely raw data
reveals that the sonde was reading about 978 hPa well before launch,
then suddenly dropped to 886.8 at which it remained stable for several
minutes, then began slowly decreasing as would be expected after launch.
My best guess is that the sonde was somehow damaged during handling
before launch resulting in erroneous pressure values.  Relative pressure
changes from an 'apparent' surface value of 886.8 hPa may be correct,
but the absolute pressure values are not.

Pressure jump at launch
DataStreams:sgpsondewrpnC1.a1
Description:
The difference between the first pressure value recorded by the radiosonde
after launch (984.5) that the surface value entered by the operator (989.3)
is somewhat larger than would normally be expected.  This will result in
incorrect altitude values throughout the sounding.  The ascent rates
during the first 30 seconds also will be incorrect.

Description:
Radiosondes manufactured at Vaisala's Woburn, MA factory during the first
of January 1998 have incorrect serial numbers.  Instead of being numbered
8012XXXXX these sondes are numbered 7012XXXXX.  Vaisala has been informed
of this, has confirmed the problem, and has corrected their numbering for
all subsequent sondes.  163 incorrectly numbered sondes were shipped to ARM
on 1/9/98.  Some have been used at the CF since 1/19/98:1430.

SGP/SONDE - Pressure jump at launch
DataStreams:sgpsondewrpnC1.00, sgpsondewrpnC1.a0, 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.
