read_grid_offline

INTERFACE:

   subroutine read_grid_offline()

DESCRIPTION:

   Read land model grid when mode is offline.
   If namelist variable mksrf_offline_fgrid is the empty string, then
   the corresponding file will be used to determine the land model grid
   Assume that the input data file has the land grid in the following 
   form:
   lon                    => dimension
   lat                    => dimension
   lon(lsmlon)            => full grid longitudes
   nlon(lsmlat)           => reduced grid number of lats per lon
   rlon(lsmlon,lsmlat)    => reduced grid longitudes
   lat(lsmlat)            => grid latitudes
   oro(lsmlon,lsmlat)     => 2d land mask
   landfrac(lsmlon,lsmlat)=> 2d land fraction
