Bad sounding file CF 970622:0228

It appears that there was a problem with the radiosonde that generated
this short file. The pressure values are unreasonably high and the
file terminated after only 484 seconds of flight.  I note that the
operators started a new sounding at 0252.  This entire file should be
disregarded or deleted.
