Subject:
SGP/SONDE/C1 - Operator used wrong calibration tape
DataStreams:sgpsondeC1.a0, sgpsondeC1.00, sgpsondewrpnC1.00, sgpsondeC1.a1, sgpsondewrpnC1.a0,
sgpsondewndcalcC1.c1, sgpsondewrpnC1.a1
Description:
It appears as if the operators had a problem with the original sounding
and launched a second radiosonde.  Apparently they used the calibration
tape that came with the first radiosonde (serial number 943156405) in
place of the one that was correct for the second radiosonde (sn 943156406)
and all the data are bad after the first sample (surface values).
Suggestions: 
The data cannot be corrected.  I would delete the whole file.
