- Pressure units are mb.  

- All levels (mandatory, significant, etc.) with pressure between P(bottom) 
  and P(top) are affected.  

- P(bottom) must be >= P(top), e.g., P(bottom) = 1000 and P(top) = 700 is OK,
  P(bottom) = 700 and P(top) = 1000 is not.

- Level code 00 will affect all levels for the station.
