Subject:	TWP/SONDE/C2 - Operator used wrong calibration tape
DataStreams:	twpsondewnpnC2.b1
Description:	It appears as though the opperator used the wrong calibration tape for this sounding. The primary symptom is a jump in temperature from a surface value of 30.1 degC to the first value aloft of 61.0 degC. Secondly, the recorded serial number for this sounding is Z1430179 which is the same serial number recorded for the previous sounding. This problem points to three failures of procedure (I have notified TWP site ops by e-mail). The first failure is using the wrong tape. The second failure is not checking the radiosonde values before launch which relates to the third failure of not entering the radiosonde values as the surface values of the sounding.
