|

First item corresponds to GLACIER_REGION with ID 0 in the surface dataset,

|
|
Allowed values are:
|
|
'multiple': grid cells can potentially have multiple glacier elevation classes,
|
|
but no virtual columns
|
|
'virtual': grid cells have virtual columns: values are computed for every glacier
|
|
elevation class, even those with 0 area (in order to provide surface mass
|
|
balance for every glacier elevation class).
|
|
'single_at_atm_topo': glacier landunits in these grid cells have a single column,
|
|
whose elevation matches the atmosphere's topographic height (so that there is no
|
|
adjustment due to downscaling)
|
|
Behavior of 'virtual' is required in the region where we have an ice sheet model

First item corresponds to GLACIER_REGION with ID 0 in the surface dataset,
|
|
second to GLACIER_REGION with ID 1, etc.
|
|
Allowed values are:
|
|
'replaced_by_ice': any melted ice runs off and is immediately replaced by solid ice;
|
|
this results in positive liquid runoff and negative ice runoff
|
|
'remains_in_place': any melted ice remains in place as liquid until it refreezes;
|
|
thus, ice melt does not result in any runoff
|
|
IMPORTANT NOTE: Regions with the 'remains_in_place' behavior also do not
|
|
compute SMB (because negative SMB would be pretty much meaningless in
|
|
those regions). Thus, you cannot use this behavior where GLC is
|
|
operating.
|
|
Regions with the 'replaced_by_ice' behavior also compute SMB for the
|
|
vegetated column.

|
|
First item corresponds to GLACIER_REGION with ID 0 in the surface dataset,
|
|
second to GLACIER_REGION with ID 1, etc.
|
|
Allowed values are:
|
|
'remains_ice': ice runoff is sent to the river model as ice; this is a crude parameterization
|
|
of iceberg calving, and so is appropriate in regions where there is substantial iceberg calving
|
|
in reality
|
|
'melted': ice runoff generated by the CLM physics (primarily due to snow capping) is melted
|
|
(generating a negative sensible heat flux) and runs off as liquid; this is appropriate in
|
|
regions that have little iceberg calving in reality. This can be important to avoid unrealistic
|
|
cooling of the ocean and consequent runaway sea ice growth.
|
|
Only applies when melt_non_icesheet_ice_runoff is .true.

<entry id="glc_snow_persistence_max_days" type="integer" category="clm_physics"

group="clm_inparm" valid_values="" >
|
|
Number of days before one considers the perennially snow-covered point 'land ice'
|
|
(and thus capable of generating a positive surface mass balance for the glacier model).
|
|
This is meant to compensate for the fact that, with small values of h2osno_max,
|
|
the onset of a snow-capped state (and thus conversion to land ice) can occur in an
|
|
unrealistically short amount of time.
|
|
Thus, in general, large values of h2osno_max should have glc_snow_persistence_max_days = 0;
|
|
small values of h2osno_max should have glc_snow_persistence_max_days > 0.

group="dynamic_subgrid" valid_values="">
|
|
If TRUE, reset baseline values of total column water and energy in the
|
|
first step of the run. This should typically be set when transitioning
|
|
from an offline spinup to a coupled run with transient glaciers, and
|
|
*possibly* when transitioning from the spinup to the transient portion
|
|
of a coupled run with transient glaciers; it should typically remain
|
|
unset at other times.
|
|
|
|
These baseline values are computed only for particular columns
|
|
(currently, only for glacier columns). They provide values that are
|
|
subtracted from the current state when counting total column water and
|
|
energy. For glacier columns, these discount the water and energy
|
|
contents in the "virtual" glacier ice, while adding representative
|
|
amounts of water and energy in the non-explicitly-modeled soil beneath
|
|
the ice. Subtracting these baselines reduces the fictitious dynbal
|
|
fluxes generated when total grid cell water and energy changes as a
|
|
result of dynamic column/landunit areas.
|
|
|
|
These baseline values are initially computed based on cold start
|
|
states. If this flag remains unset (.false.), these baseline values will
|
|
remain fixed at their cold start values. This will conserve mass and
|
|
energy, but may result in larger-than-desired dynbal energy fluxes (and,
|
|
in principle, also larger dynbal water fluxes; but currently, the mass
|
|
of glacier ice remains fixed over time, so dynbal water fluxes are
|
|
fairly small regardless of whether this flag is ever set). To further
|
|
reduce these dynbal fluxes, you can set this flag to .true. when
|
|
starting a startup or hybrid run from a partially or entirely spun-up
|
|
state. This will reset the baseline values based on the state at the
|
|
start of this run.
|
|
|
|
Note that setting this flag can break water and energy conservation!
|
|
Specifically, any water and energy that has previously been added to or
|
|
removed from states that contribute to these baselines (currently, (a)
|
|
glacier ice and (b) soil water and energy in the vegetated landunit in
|
|
the same grid cell as glaciers) will effectively be ignored when
|
|
computing conservation corrections due to land cover change. Instead,
|
|
only the change in states from this point forward will be
|
|
considered. So, for example, this flag should NOT be set when
|
|
transitioning from a historical run to a future scenario.
|
|
|
|
This setting only impacts startup and hybrid runs; it has no effect in a
|
|
continue run; it is an error for this to be set in a branch
|
|
run. Furthermore, this setting has no effect in a cold start run.

If TRUE, set the dynbal water and energy fluxes to zero. This should typically
|
|
only be done for testing: This is needed in some tests where we have daily
|
|
rather than annual glacier dynamics: if we allow the true dynbal adjustment
|
|
fluxes in those tests, we end up with sensible heat fluxes of thousands of W m-2
|
|
or more, which causes CAM to blow up. However, note that setting it to true will

break water and energy conservation!

This is useful when transitioning from a spinup under one set of atmospheric forcings

we make it more likely that points will remain only seasonally snow-covered under the new

When resetting snow pack over glacier columns, one can choose to do this over all glacier
|
|
columns, or only those below a certain elevation. A typical use case is to reset only those
|
|
columns that have a seasonal snow pack in the real world, i.e. SMB less than 0, also known as
|
|
the equilibrium line altitude (ELA). This parameter sets a single global ELA value. By
|
|
setting this parameter to a large value (i.e. 10000 m), all glacier columns will be reset.

Method to use for init_interp. Only applies when use_init_interp = .true.
|
|
|
|
'general': The general-purpose method that can be used when changing
|
|
grids, configurations, etc. This starts off with subgrid areas taken
|
|
from the surface dataset.
|
|
|
|
'use_finidat_areas': This starts off with subgrid areas taken from the
|
|
input finidat file. This is needed to achieve bit-for-bit results in a
|
|
coupled case (where areas in initialization impact initial fields sent
|
|
to the atmosphere) (but using the 'general' method will typically have
|
|
only a very minor impact on results in this case). For this method to
|
|
work, the input finidat file needs to be at the same resolution as the
|
|
current configuration. So this is a less general form of
|
|
init_interp. However, it can be used in cases where the only difference
|
|
is in internal memory allocation. In order to catch possible problems,
|
|
this uses a different algorithm for finding the input point for each
|
|
output point, which ensures that each active output point is associated
|
|
with exactly one input point with the same latitude, longitude and
|
|
type. This method requires (a) the same grid for input and output,
|
|
within roundoff; (b) any non-zero-weight point in the input must have
|
|
memory allocated for it in this grid cell in the output (this will be
|
|
satisfied if the point is non-zero-weight on the surface dataset or if
|
|
it's a point for which we allocate memory even for zero-weight points);
|
|
(c) any active point in the output (based on the surface dataset and
|
|
rules for determining active points) must have a matching point in this
|
|
grid cell in the input. (Note that this generally can NOT be used when
|
|
transitioning from a spinup run to a transient run, because spinup runs
|
|
typically have irrigation off and transient runs have irrigation on, and
|
|
the presence/absence of irrigation affects the subgrid structure; if it
|
|
weren't for that difference, then this option would be useful for this
|
|
use case.)
