of rocoto available. For most pre-configured platforms, rocoto can be
loaded via a module:
> module load rocoto
For more details on rocoto, see the User's Guide.
To launch the workflow, first ensure that you have a compatible version
of rocoto loaded. For example, to load version 1.3.1 of rocoto, use
> module load rocoto/1.3.1
(This version has been tested on hera; later versions may also work but
have not been tested.)
To launch the workflow, change location to the experiment directory
(EXPTDIR) and issue the rocotrun command, as follows:
> cd {EXPTDIR}
> {rocotorun_cmd}
To check on the status of the workflow, issue the rocotostat command
(also from the experiment directory):

Note that:
1) The rocotorun command must be issued after the completion of each
task in the workflow in order for the workflow to submit the next
task(s) to the queue.
2) In order for the output of the rocotostat command to be up-to-date,
the rocotorun command must be issued immediately before issuing the

# The grid generation script grid_gen_scr called below in turn calls the
# make_hgrid utility/executable to construct the regional grid. make_-
# hgrid accepts as arguments the index limits (i.e. starting and ending
# indices) of the regional grid on the supergrid of the regional grid's
# parent tile. The regional grid's parent tile is tile 6, and the su-
# pergrid of any given tile is defined as the grid obtained by doubling
# the number of cells in each direction on that tile's grid. We will
# denote these index limits by
#
# istart_of_t7_on_t6sg
# iend_of_t7_on_t6sg
# jstart_of_t7_on_t6sg
# jend_of_t7_on_t6sg
#
# The "_T6SG" suffix in these names is used to indicate that the indices
# are on the supergrid of tile 6. Recall, however, that we have as in-
# puts the index limits of the regional grid on the tile 6 grid, not its
# supergrid. These are given by
#
# istart_of_t7_on_t6g
# iend_of_t7_on_t6g
# jstart_of_t7_on_t6g
# jend_of_t7_on_t6g
#
# We can obtain the former from the latter by recalling that the super-
# grid has twice the resolution of the original grid. Thus,
#
# istart_of_t7_on_t6sg = 2*istart_of_t7_on_t6g - 1
# iend_of_t7_on_t6sg = 2*iend_of_t7_on_t6g

# jend_of_t7_on_t6sg = 2*jend_of_t7_on_t6g
#
# These are obtained assuming that grid cells on tile 6 must either be
# completely within the regional domain or completely outside of it,
# i.e. the boundary of the regional grid must coincide with gridlines
# on the tile 6 grid; it cannot cut through tile 6 cells. (Note that
# this implies that the starting indices on the tile 6 supergrid must be
# odd while the ending indices must be even; the above expressions sa-
# tisfy this requirement.) We perfrom these calculations next.

# If we simply pass to make_hgrid the index limits of the regional grid
# on the tile 6 supergrid calculated above, make_hgrid will generate a
# regional grid without a halo. To obtain a regional grid with a halo,
# we must pass to make_hgrid the index limits (on the tile 6 supergrid)
# of the regional grid including a halo. We will let the variables
#
# istart_of_t7_with_halo_on_t6sg
# iend_of_t7_with_halo_on_t6sg
# jstart_of_t7_with_halo_on_t6sg
# jend_of_t7_with_halo_on_t6sg
#
# denote these limits. The reason we include "_wide_halo" in these va-
# riable names is that the halo of the grid that we will first generate
# will be wider than the halos that are actually needed as inputs to the
# FV3LAM model (i.e. the 0-cell-wide, 3-cell-wide, and 4-cell-wide halos
# described above). We will generate the grids with narrower halos that
# the model needs later on by "shaving" layers of cells from this wide-
# halo grid. Next, we describe how to calculate the above indices.
#
# Let halo_width_on_t7g denote the width of the "wide" halo in units of number of
# grid cells on the regional grid (i.e. tile 7) that we'd like to have
# along all four edges of the regional domain (left, right, bottom, and
# top). To obtain the corresponding halo width in units of number of
# cells on the tile 6 grid -- which we denote by halo_width_on_t6g -- we simply di-
# vide halo_width_on_t7g by the refinement ratio, i.e.
#
# halo_width_on_t6g = halo_width_on_t7g/refine_ratio_t6g_to_t7g
#
# The corresponding halo width on the tile 6 supergrid is then given by
#
# halo_width_on_t6sg = 2*halo_width_on_t6g
# = 2*halo_width_on_t7g/refine_ratio_t6g_to_t7g
#
# Note that halo_width_on_t6sg must be an integer, but the expression for it de-
# rived above may not yield an integer. To ensure that the halo has a
# width of at least halo_width_on_t7g cells on the regional grid, we round up the
# result of the expression above for halo_width_on_t6sg, i.e. we redefine halo_width_on_t6sg
# to be
#
# halo_width_on_t6sg = ceil(2*halo_width_on_t7g/refine_ratio_t6g_to_t7g)
#
# where ceil(...) is the ceiling function, i.e. it rounds its floating
# point argument up to the next larger integer. Since in bash division
# of two integers returns a truncated integer and since bash has no
# built-in ceil(...) function, we perform the rounding-up operation by
# adding the denominator (of the argument of ceil(...) above) minus 1 to
# the original numerator, i.e. by redefining halo_width_on_t6sg to be
#
# halo_width_on_t6sg = (2*halo_width_on_t7g + refine_ratio_t6g_to_t7g - 1)/refine_ratio_t6g_to_t7g
#
# This trick works when dividing one positive integer by another.
#
# In order to calculate halo_width_on_t6g using the above expression, we must
# first specify halo_width_on_t7g. Next, we specify an initial value for it by
# setting it to one more than the largest-width halo that the model ac-
# tually needs, which is NH4. We then calculate halo_width_on_t6sg using the
# above expression. Note that these values of halo_width_on_t7g and halo_width_on_t6sg will
# likely not be their final values; their final values will be calcula-
# ted later below after calculating the starting and ending indices of
# the regional grid with wide halo on the tile 6 supergrid and then ad-
# justing the latter to satisfy certain conditions.

#
# With an initial value of halo_width_on_t6sg now available, we can obtain the
# tile 6 supergrid index limits of the regional domain (including the
# wide halo) from the index limits for the regional domain without a ha-

# Create globbing patterns for grid, orography, and surface climatology
# files.
#
#
# For grid files (i.e. file_group set to "grid"), symlinks are created
# in the FIXLAM directory to files (of the same names) in the GRID_DIR.
# These symlinks/files and the reason each is needed is listed below:
#
# 1) "C*.mosaic.halo${NHW}.nc"
# This mosaic file for the wide-halo grid (i.e. the grid with a ${NHW}-
# cell-wide halo) is needed as an input to the orography filtering
# executable in the orography generation task. The filtering code
# extracts from this mosaic file the name of the file containing the
# grid on which it will generate filtered topography. Note that the
# orography generation and filtering are both performed on the wide-
# halo grid. The filtered orography file on the wide-halo grid is then
# shaved down to obtain the filtered orography files with ${NH3}- and
# ${NH4}-cell-wide halos.
#
# The raw orography generation step in the make_orog task requires the
# following symlinks/files:
#
# a) C*.mosaic.halo${NHW}.nc
# The script for the make_orog task extracts the name of the grid
# file from this mosaic file; this name should be
# "C*.grid.tile${TILE_RGNL}.halo${NHW}.nc".
#
# b) C*.grid.tile${TILE_RGNL}.halo${NHW}.nc
# This is the
# The script for the make_orog task passes the name of the grid
# file (extracted above from the mosaic file) to the orography
# generation executable. The executable then
# reads in this grid file and generates a raw orography
# file on the grid. The raw orography file is initially renamed "out.oro.nc",
# but for clarity, it is then renamed "C*.raw_orog.tile${TILE_RGNL}.halo${NHW}.nc".
#
# c) The fixed files thirty.second.antarctic.new.bin, landcover30.fixed,
# and gmted2010.30sec.int.
#
# The orography filtering step in the make_orog task requires the
# following symlinks/files:
#
# a) C*.mosaic.halo${NHW}.nc
# This is the mosaic file for the wide-halo grid. The orography
# filtering executable extracts from this file the name of the grid
# file containing the wide-halo grid (which should be
# "${CRES}.grid.tile${TILE_RGNL}.halo${NHW}.nc"). The executable then
# looks for this grid file IN THE DIRECTORY IN WHICH IT IS RUNNING.
# Thus, before running the executable, the script creates a symlink in this run directory that
# points to the location of the actual wide-halo grid file.
#
# b) C*.raw_orog.tile${TILE_RGNL}.halo${NHW}.nc
# This is the raw orography file on the wide-halo grid. The script
# for the make_orog task copies this file to a new file named
# "C*.filtered_orog.tile${TILE_RGNL}.halo${NHW}.nc" that will be
# used as input to the orography filtering executable. The executable
# will then overwrite the contents of this file with the filtered orography.
# Thus, the output of the orography filtering executable will be
# the file C*.filtered_orog.tile${TILE_RGNL}.halo${NHW}.nc.
#
# The shaving step in the make_orog task requires the following:
#
# a) C*.filtered_orog.tile${TILE_RGNL}.halo${NHW}.nc
# This is the filtered orography file on the wide-halo grid.
# This gets shaved down to two different files:
#
# i) ${CRES}.oro_data.tile${TILE_RGNL}.halo${NH0}.nc
# This is the filtered orography file on the halo-0 grid.
#
# ii) ${CRES}.oro_data.tile${TILE_RGNL}.halo${NH4}.nc
# This is the filtered orography file on the halo-4 grid.
#
# Note that the file names of the shaved files differ from that of
# the initial unshaved file on the wide-halo grid in that the field
# after ${CRES} is now "oro_data" (not "filtered_orog") to comply
# with the naming convention used more generally.
#
# 2) "C*.mosaic.halo${NH4}.nc"
# This mosaic file for the grid with a 4-cell-wide halo is needed as
# an input to the surface climatology generation executable. The
# surface climatology generation code reads from this file the number
# of tiles (which should be 1 for a regional grid) and the tile names.
# More importantly, using the ESMF function ESMF_GridCreateMosaic(),
# it creates a data object of type esmf_grid; the grid information
# in this object is obtained from the grid file specified in the mosaic
# file, which should be "C*.grid.tile${TILE_RGNL}.halo${NH4}.nc". The
# dimensions specified in this grid file must match the ones specified
# in the (filtered) orography file "C*.oro_data.tile${TILE_RGNL}.halo${NH4}.nc"
# that is also an input to the surface climatology generation executable.
# If they do not, then the executable will crash with an ESMF library
# error (something like "Arguments are incompatible").
#
# Thus, for the make_sfc_climo task, the following symlinks/files must
# exist:
# a) "C*.mosaic.halo${NH4}.nc"
# b) "C*.grid.tile${TILE_RGNL}.halo${NH4}.nc"
# c) "C*.oro_data.tile${TILE_RGNL}.halo${NH4}.nc"
