Re: code and reference of "wrf_dbz" in NCL

See attached.

In general, if anybody wants to find a Fortran routine that is used in a built-in function in NCL, you can download the NCL source code,
look in the "$NCARG/ni/src/lib/nfp" directory for the wrapper ("wrf_dbz_W"):

 % cd $NCARG/ni/src/lib/nfp
% grep wrf_dbz_W *.c
wrapper.c:extern NhlErrorTypes wrf_dbz_W(void);
wrapper.c: NclRegisterFunc(wrf_dbz_W,args,"wrf_dbz",nargs);
wrfW.c:NhlErrorTypes wrf_dbz_W( void )

Ignore an "wrapper.c" matches. Instead, look in "wrfW.c" for
wrf_dbz_W and see what Fortran routine it calls:

/*
 * Call the Fortran routine.
 */
    NGCALLF(calcdbz,CALCDBZ)(tmp_dbz, tmp_prs, tmp_tmk, tmp_qvp, tmp_qra,
                             tmp_qsn, tmp_qgr, &iwedim, &isndim, &ibtdim,
                             &sn0, ivarint, iliqskin);

Look in $NCARG/ni/src/lib/nfpfort for that Fortran routine:
  
% cd ../nfpfort
 % grep CALCDBZ *.f
wrf_user_dbz.f: SUBROUTINE CALCDBZ(DBZ,PRS,TMK,QVP,QRA,QSN,QGR,WEDIM,SNDIM,BTDIM,
