 '''Status of workflow development'''
 -------------------------------

 Branch
 https://svnemc.ncep.noaa.gov/projects/fv3gfs/branches/fanglin.yang/tic21
 can now be used for running following types of experiments using the fv3
 branch
 https://svnemc.ncep.noaa.gov/projects/fv3/branches/fanglinyang/tic26.
 Users should check out tic26 from NEMSfv3gfs branch from
 https://svnemc.ncep.noaa.gov/projects/nems/apps/NEMSfv3gfs/branches/jun/tic26.
 Both the workflow and model code have been updated to its respective
 trunk.  Note that only Rocoto-based workflow is supported.  The old
 workflow based on pend/psub will not be maintained from this version
 onward.

 1) Cycled experiments with DA, either with or without NSST in the
 forecast, with NSST turned off in analysis, still using nemsio_regrid for
 remapping.  (I have tested it on Luna for many cycles)

 2) Forecast only experimen using the current NEMS GSM physics, either with
 or without NSST, either using the Write Component or GFDL FMS for I/O


 The Write Component is almost ready (thanks to Jun Wang).  There are still
 a couple of minor issues. I am working with Jun to resolve them before the
 fv3 tic26 branch can be committed to the trunk.

 The workflow has been extensively modified to include NSST, GFDL MP and
 Write Component. The GFDL MP is yet to be tested. Please see
 https://svnemc.ncep.noaa.gov/trac/fv3gfs/diff?new_path=%2Fbranches%2Ffanglin.yang%2Ftic21&old_path=%2Fbranches%2Ffanglin.yang%2Ftic21&new_rev=&old_rev=
 for the detail of the changes.

 ---------------------
 A few important items
 ---------------------
 1) GMTED2010 terrain is set as the default

 2) A new config.nsst has been added to set up NSST model.  "NONST" is
 added to config.base.

 3) A new diag_table2 has been created to run with the Write Component.
 Jun and Fanglin are still working on unifying field names used in the
 model, POST and analysis.

 4) Find in config.base
    # I/O QUILTING, true--use Write Component; false--use GFDL FMS
    # if quilting=true, chose OUTPUT_GRID as cubed_sphere_grid in netcdf or
 gaussian_grid
    # if gaussian_grid, set WRITE_NEMSIOFILE for nemsio or netcdf

                 export QUILTING=".true."
                 export OUTPUT_GRID="gaussian_grid"
                 export WRITE_NEMSIOFILE=".true."

 5) set_bitmap has been added to downstream grib2 product generation
 (thanks to Wen Meng)

 6) Write Component needs ESMF lib esmf/7.1.0bs34

 7) ush/drive_makeprepbufr.sh was updated by Xu Li to get NSST bufr data.

 8) Forecast parameters in exglobal_forecast are set to those used in the
 forecast-only experiment prfv3l65d (see Fanglin's recent presentation at
 the FV3GFS weekly meeting).

 9) GFDL_MP namelist parameters have been added to exglobal_fcst script
 (Thanks to Rusty Benson).

 ...... and many other tweaks.
