Do not need vertical interpolation for
soil carbon 1 meter carbon stock.

Adding specific fast, medium, slow
turnover carbon pools

Assimilating averaged flux tower
data (hourly, monthly) requires simplified
common code obs type/quantity

Needed to reduce LH and SH quant and
obs names for text limits.

These are intended for direct interpolation
of daily averages.

Just updating namelist values
for calLMIP observations and time

Just simplified things when parsing
obs for calLMIP application

Adding land parameter quantities for CalLMIP
parameter DA. I have included a high level of
mechanism specificity anticipating I will need this
for variable localization later on.

The model_nml 6 column format now supports
new 'param' file origin and adds this new param domain
to join the original restart,history and vector clm domains.
 Adds 'estimate params' option and allows user to define which clm
PFTs to estimate parameters for. Performs parameter augmentation
to map explicit 2D lat/lon locations to global PFT parameters
(and for global scalar parameters).  Brings in new parameter
specific QTYs.

Leverages clm_to_dart to create parameter augmentation
(expansion) by mapping single global parameter value onto spatially
explicit 2D lat/lon clm grid.  This applies lat/lon history
information from history domain onto param domain.  Allows
for spatially explicit updates to parameter values and application
of spatial localization.

clm_to_dart expands parameter to spatial 2D grid,
therefore during the filter update global parameter values
will have spatially explicit updates. This commit
spatially averages the posterior parameter values
to generate a global parameter so that it can be
re-inserted into clm model for the subsequent forecast.
User options for spatial averaging based on geometric spatial average
and masks out cells where PFT is not present.  Also
has PFT-averaged option which spatially averages the
PFT specific spatial coverage to calculate global
posterior parameter value.

Adds namelist options  within model_nml, filter_nml
fill_inflation_restart_nml and clm_to_dart and dart_to_clm
specifically for parameter DA functionality

Assimilate.csh orchestrates key execution of
DART executables and links all important file defined
in namelist to DART code.  Block 4 adds the parameter
domain for functioning of fill_inflation_restart.
Block 5 provided proper linkages to parameter related
to template and expanded param files.  Block 7 performs
dart_to_clm execution and appropriate linkages.  Block 8
updates the archiving and cleanup consisten with other
domain files

Adds parameter file staging to run directory

Sets the initial parameter directory and base file
name.  Also informs the shell scripting when estimate_params
is turned on, which is required for non-Fortran related
operation of code (i.e. coordination of csh commands)

average_params_to_scalar previously used num_active_pfts > 0 to determine
whether a param variable was PFT-indexed or scalar, which incorrectly
classified scalar variables (e.g. cv) as PFT-indexed whenever any PFT
index was set. Fix by inspecting the actual variable dimensionality in
the compact param file via nf90_inquire_variable, mirroring the existing
logic in expand_params_to_grid (clm_to_dart.f90).

All variables present in input.nml:model_nml
must be declared within clm_to_dart and dart_to_clm,
otherwise unrecognized namelist error
