Discussion of Problem:
It appears that the pressure sensor was jarred during launch and jumped
readings from 975.4 hPa at the surface to 950.2 hPa at the first sample
after launch. This results in erroneous altitude values throughout the
sounding and erroneous ascent rate values during the first 30 seconds.
The relative altitude calculations after the second sample should be
correct. Although the surface wind speed was recorded at 10.3 m/s,
the next wind value is reported as 18.2 m/s - quite strong. The bouncing
of the balloon during the launch might account for the abnormal jarring
of the sonde.

Discussion of Problem:
The surface pressure for this sounding was entered by the operator as 962.6.
The first pressure value reported by the sonde is 962.4 hPa. The surface
pressure in the previous (0533) and subsequent (1429) soundings were 983.3
and 985.7 respectively. SMOS13 pressures were in the 983+ range during
this same period. It appears that the sonde pressure sensor was bad and
was used as the source of the surface pressure (this is CF standard procedure).
Both the pressure and altitude values for this sounding are likely incorrect.

Discussion of Problem:
The site operator inadvertently entered incorrect surface met values for
the subject sounding. Although he caught the error soon after launch
and reported it immediately, it was too late to correct. The following
table shows the incorrect (present in the file) and correct values.
Incorrect Correct
Pressure 1000.0 973.9
Temperature 35.0 30.5
Relative Humidity 27 30
The incorrect values of surface temperature and relative humidity will not
affect the other values in the sounding. The incorrect surface pressure
will, however, affect the altitude calculation throughout the sounding.

What location was the data collected at: CF
Period of time in question
Begin Date 07/01/96 Time 11:30 (GMT)
End Date Time (GMT)
Data should be labeled:
___ questionable ___ All data fields affected
_X_ incorrect _X_ Only some data fields affected
___ wrong calibration
___ others
Discussion of Problem:
The surface pressure for this sounding was entered by the operator as 996.4
hPa. The first pressure value reported by the sonde is 972.3 hPa. The surface
pressure at 05:30 was 972.3 and at 14:46 was 976.1. 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 1001.4
hPa. The first pressure value reported by the sonde is 979.7 hPa. It appears
that the operator incorrectly entered sea-level pressure obtained from the
WeatherMeasure set rather than surface pressure obtained from the radiosonde.

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.
