!> MODULE BDCOMB
!>
!> ABSTRACT:
!> MODULE BDCOMB CONTAINS RANDOM BAND PARAMETERS FOR THE LW CALCULATIONS USING COMBINED WIDE 
!> FREQUENCY BANDS BETWEEN 160 AND 1200 CM-1,AS WELL AS THE 2270-2380 BAND FOR SOURCE CALC.
!> BANDS 1-8:  COMBINED WIDE FREQUENCY BANDS FOR 160-560 CM-1
!> BANDS 9-14: FREQUENCY BANDS,AS IN BANDTA (NARROW BANDS) FOR 560-1200 CM-1
!> BAND  15:   FREQUENCY BAND 2270-2380 CM-1,USED FOR SOURCE CALCULATION ONLY THUS NBLY PRESENTLY
!>             EQUALS 15
!>
!> BANDS ARE ARRANGED IN ORDER OF INCREASING WAVENUMBER
!>
!> ACOMB        - RANDOM "A" PARAMETER FOR (NBLY) BANDS
!> BCOMB        - RANDOM "B" PARAMETER FOR (NBLY) BANDS
!> BETACM       - CONTINUUM COEFFICIENTS FOR (NBLY) BANDS
!> APCM , BPCM  - CAPPHI COEFFICIENTS FOR (NBLY) BANDS
!> ATPCM, BTPCM - CAPPSI COEFFICIENTS FOR (NBLY) BANDS
!> BDLOCM       - LOWEST FREQUENCY IN EACH OF (NBLY) FREQ. BANDS
!> BDHICM       - HIGHEST FREQUENCY IN EACH OF (NBLY) FREQ. BANDS
!> AO3CM        - RANDOM "A" PARAMETER FOR OZONE IN (3) OZONE BANDS
!> BO3CM        - RANDOM "B" PARAMETER FOR OZONE IN (3) OZONE BANDS
!> AB15CM       - THE PRODUCT ARNDM*BRNDM FOR THE TWO BANDS REPRESENTING THE 15 UM BAND COMPLEX 
!>                OF CO2
!> BETINC       - CONT.COEFFICIENT FOR A SPECIFIED WIDE FREQ.BAND (800-990 AND 1070-1200 CM-1).
!> IBAND        - INDEX NO OF THE 40 WIDE BANDS USED IN COMBINED WIDE BAND CALCULATIONS. IN OTHER
!>                WORDS, INDEX TELLING WHICH OF THE 40 WIDE BANDS BETWEEN 160-560 CM-1 ARE INCLUDED
!>                IN EACH OF THE FIRST 8 COMBINED WIDE BANDS
!>
!> DATA FOR ACOMB, BCOMB, APCM, BPCM, ATPCM, BTPCM, AO3CM, BO3CM ARE OBTAINED BY USING THE AFGL 
!> 1982 CATALOG. 
!> CONTINUUM COEFFICIENTS ARE FROM ROBERTS 1976. 
!> IBAND INDEX VALUES ARE OBTAINED BY EXPERIMENTATION.
