Description

Currently the ccpp-physics has dependency on splat from sp library. The dependency can be removed.

Solution

Two solutions are proposed:

remove the Gaussian grid support for the fixed files read in the ccpp-physics. Currently model has the capability to read in the fixed files on the native tiled grid. So if model switches to use the tiled files, the dependency of sp lib can be removed.
the splat used in ccpp-physics from sp lib is a small Fortran subroutine without further dependency on any other file and it is available in the fv3/io. It is possible to use one version of splat shared by both ccpp-physics and fv3/io. This way the Gaussian grid fixed file will still be supported in ccpp-physics.

Related to

Directly reference any issues or PRs in this or other repositories that this is related to, and describe how they are related.

Update update will be in ccpp-physics.

Solution (2) replaces the sp lib dependency with another dependency, unless you want to move the routine into ccpp-physics and then use it in fv3atm (I don't think we should do this, because it is really a shared dependency).

Another option would be to duplicate the splat routine and add it to sfcsub.F, but I do not like this approach either.

I prefer solution (1) if we are sure that we don't need to support reading Gaussian grid fixed files in ccpp-physics in the future.

These latlon fixed files are used by the model (according to control regression test):

FNAISC   latlon   CFSR.SEAICE.1982.2012.monthly.clim.grb
FNALBC2  latlon   global_albedo4.1x1.grb
FNGLAC   latlon   global_glacier.2x2.grb
FNMXIC   latlon   global_maxice.2x2.grb
FNVMXC   latlon   global_shdmax.0.144x0.144.grb
FNVMNC   latlon   global_shdmin.0.144x0.144.grb
FNSLPC   latlon   global_slope.1x1.grb
FNSNOC   latlon   global_snoclim.1.875.grb
FNTG3C   latlon   global_tg3clim.2.6x1.5.grb
FNVEGC   latlon   global_vegfrac.0.144.decpercent.grb
         latlon   global_zorclim.1x1.grb
FNTSFC   latlon   RTGSST.1982.2012.monthly.clim.grb

and these Gaussian fixed files:

FNABSC   gaussian global_mxsnoalb.uariz.t126.384.190.rg.grb
FNMSKH   gaussian global_slmask.t1534.3072.1536.grb
FNALBC   gaussian global_snowfree_albedo.bosu.t126.384.190.rg.grb
FNSMCC   gaussian global_soilmgldas.statsgo.t1534.3072.1536.grb
         gaussian global_soilmgldas.t126.384.190.grb
FNSOTC   gaussian global_soiltype.statsgo.t126.384.190.rg.grb
FNVETC   gaussian global_vegtype.igbp.t126.384.190.rg.grb

Maybe we can just convert these gaussian to latlon. Do they have to be on Gaussian grid? I doubt.

sfcsub.F is designed to run for any random sets of grid-points as long as latitude/longitudes are defined. That is how it works for SCM, basically a set of random grid columns. This functionality requires to use either lat/lon or Gaussian grid grib1 files as input; netcdf files will not work.

I don't know much about ccpp-SCM. However, it used to work for all earlier versions of NCEP/SCM (including the version Fnglin worked with many years ago). I don't see why it should not work with ccpp-SCM. Actually, it can work with any grid-point models.

Also, SCM grid points need not be on a "fv3" grid. It could be any location on the globe. One more point to consider is to run the model using analysis as input; which is important in making AMIP style runs. Arun Kumar's group at CPC is already trying to do this with a version of FV3. Disabling this capability is not progress. On Mon, Jul 12, 2021 at 3:00 PM Dom Heinzeller ***@***.***> wrote:

Moorthi, what analysis file is this? Does the analysis have to be on the Gaussian grid? On Mon, Jul 12, 2021 at 3:04 PM SMoorthi-emc ***@***.***> wrote:

I agree with Moorthi. The model should support AMIP-type experiments which use observed SSTs, usually saved either on Gaussian grid or la-tlon grid, as input. To a minimum, the support for input on global lat-lon grids needs to be maintained. Fanglin On Mon, Jul 12, 2021 at 3:04 PM SMoorthi-emc ***@***.***> wrote:

When you make AMIP runs, you normally provide observed SST analysis, sea-ice analysis and snow analysis, generally daily analysis. These need to be provided as grib1 files on either lat/lon or Gassian grid - grib1 files are self-describing. sfcsub.F can use this analysis and interpolate to any grid points provided via the argument - so it can be used in any models, including SCM. It does not have the capability to ingest netcdf analysis files, unless someone is willing to write appropriate code.

Another option that came up has to do with the "gray zone" where this functionality belongs. It is debatable whether this code (nudging towards sfc climatology) should be part of the physics or the host models. If it is agreed that the latter is the case, then the surface subcycling should be moved out of ccpp-physics into fv3atm.
