exgdas_atmos_gldas.sh topodir needs /

[RussTreadon-NOAA]

Expected behavior
gdasgldas executable gdas2gldas should run to completion without error.

Current behavior
gdasgldas fails when executing gdas2gldas with the following error

28:  - CALL GridCreateMosaic FOR INPUT GRID
 9: NetCDF Error: /work/noaa/da/Russ.Treadon/git/global_workflow/develop/fix/orog/C96C96_grid.tile1.nc : No such file or directory
12: NetCDF Error: /work/noaa/da/Russ.Treadon/git/global_workflow/develop/fix/orog/C96C96_grid.tile1.nc : No such file or directory
13: NetCDF Error: /work/noaa/da/Russ.Treadon/git/global_workflow/develop/fix/orog/C96C96_grid.tile1.nc : No such file or directory

Machines affected
Failure detected on Orion. Same failure will likely occur on other machines.

To Reproduce
Install the g-w develop at e915eb6. Set up EXPDIR to run a parallel. Populate ROTDIR with the files needed to fully execute gdasgldas. Submit gdasgldas.

Additional Information
Notice that sorc/gldas.fd/scripts/exgdas_atmos_gldas.sh defines topodir as

export topodir=${topodir:-$HOMEgfs/fix/fix_fv3_gmted2010/$CASE/}

whereas the g-w scripts/exgdas_atmos_gldas.sh defines topodir as

export topodir=${topodir:-${HOMEgfs}/fix/orog/${CASE}}

The g-w copy drops the trailing /. The gldas copy includes the trailing /.

Possible Implementation
Add the trailing / to topodir defintion in scripts/exgdas_atmos_gldas.sh. I did this in a working copy of the develop g-w. This got my execution of gdasgldas past the gdas2gldas failure.
