C Revision 001:  J. Halle    *CMDA/AES April 2003.
C                - Added RLIMLVHU variable in the common block.

C
C    COMDECK COMFILT :  Dimensions and arrays needed in order
C     ---------------   to filter out unwanted data of CMA file
C                       before assimilation by the 3d-var analysis.
C
C      NELEMS      : NUMBER of variable types to assimilate.
C      NLIST(30)   : List containing WHICH variable types to assimilate.
C      NFLAGS      : NUMBER of bits to verify in Quality Control Flag.
C      NLISTFLG(15): List containing WHICH bits are to be verified in
C     .               in Quality Control Flag.
C      LTOPOFILT   : If true, apply filter of observations because
C                    model topography differs from station topography
C      DSTEPOBS    : Time step (in hours) of data assimilation (fgat/4Dvar)
c      NLWRBIN     : Bin number of the lower assimilation window boundery
c      NUPRBIN     : Bin number of the upper assimilation window boundery
C      RLIMLVHU    : Top level of humidity analysis (mbs).
