                       GUSTAV90_700MB.CTR

Zero time is 0000Z on the morning of Aug. 27, 1990.
   8   27   1990   ! Zero time in integer month, day and year.
This center file was used to generate the global track GUSTAV90_700MB.TRK,
   which in turn was used for processing the GUSTAV90 flights that were 
   flown at a standard pressure of 700 mb (except the 28H flight): 
   GUSTAV90_29H, GUSTAV90_30H, and the logical flight GUSTAV90_31HA.
Pressures listed in far right hand column on some of the lines are
    standard pressures, not actual measured pressures for the given
    center times. 
The fourth column holds weighting factors.
