#include "FIZHI_OPTIONS.h"
       subroutine fizhi_init_fixed (myThid)
c-----------------------------------------------------------------------
c  Routine to initialise the fizhi package.
c  
c  Input: myThid       - Process number calling this routine
c
c  Notes: 
c   1) This routine is the interface to read input datasets and set
c      other fixed variables for fizhi
c      the datasets are:
c         vegetation (data for each tile at every grid point)
c         ozone (varies with lat, height and time - read it all in
c                   now and interpolate between values later)
c      the other fixed parameters are:
c         N2O, Methane (vary with space)
c         CO2, CFC11, CFC12, CFC22 (set to a global value)
c   3) For now, the fizhi package contains the alarms and clocks
c      routines, so this routine will also initialize the alarms.
