<desc> DOCN mode. The data ocean component (DOCN) always returns SSTs to the
driver. The atmosphere/ocean fluxes are computed in the
coupler. Therefore, the data ocean model does not compute fluxes like
the data ice model. DOCN has two distinct modes of operation. It can
run as a pure data model, reading in ocean SSTs (normally
climatological) from input datasets, performing time/spatial
interpolations, and passing these to the coupler. Alternatively,
DOCN can compute updated SSTs by running as a slab ocean model where
bottom ocean heat flux convergence and boundary layer depths are read
in and used with the atmosphere/ocean and ice/ocean fluxes obtained
from the driver.
--- A setting of prescribed assumes the only field in the input stream is SST.
It also assumes the SST is in Celsius and must be converted to Kelvin.
All other fields are set to zero except for ocean salinity, which is set to a
constant reference salinity value. Normally the ice fraction data is found in
the same data files that provide SST data to the data ocean model. They are
normally found in the same file because the SST and ice fraction data are derived
from the same observational data sets and are consistent with each other.
--- Settings of som (slab ocean model) or som_aquap (aquaplanet slab ocean) are
prognostic modes which compute a prognostic sea surface temperature and a
freeze/melt potential (surface Q-flux) used by the sea ice model. This
calculation requires an external SOM forcing data file that includes
ocean mixed layer depths and bottom-of-the-slab Q-fluxes.
Scientifically appropriate bottom-of-the-slab Q-fluxes are normally
ocean resolution dependent and are derived from the ocean model output
of a fully coupled CCSM run. Note that while this mode runs out of
the box, the default SOM forcing file is not scientifically
appropriate and is provided for testing and development purposes only.
Users must create scientifically appropriate data for their particular
application. A tool is available to derive valid SOM forcing.
--- A setting of sst_aquapN (where "N" is an integer index value) is a
type of prescribed SST mode used specifically for an aquaplanet setup in
which global SSTs correspond to an analytic form set by the index value.
Currently, indices for 10 SST profiles are supported [e.g., index 3 corresponds
to the "QOBS" profile of Neale and Hoskins (2001, Atmos. Sci. Lett.)].
With source code modifications, it is possible for users to create their own
analytic SST distributions and match them to indices 11 or greater.

<desc>The model year that corresponds to SSTICE_YEAR_START on the data file.
Prescribed SST and ice coverage data will be aligned so that the first year of
data corresponds to SSTICE_YEAR_ALIGN in the model. For instance, if the first
year of prescribed data is the same as the first year of the model run, this
should be set to the year given in RUN_STARTDATE.
If SSTICE_YEAR_ALIGN is later than the model's starting year, or if the model is
run after the prescribed data ends (as determined by SSTICE_YEAR_END), the
default behavior is to assume that the data from SSTICE_YEAR_START to
SSTICE_YEAR_END cyclically repeats. This behavior is controlled by the
"taxmode" stream option; see the data model documentation for more details.

<desc>
General method that operates on the data. This is generally
implemented in the data models but is set in the strdata method for
convenience.
datamode = "NULL"
NULL is always a valid option and means no data will be generated.
Turns off the data model as a provider of data to the coupler. The
ice_present flag will be set to false and the coupler will assume no
exchange of data to or from the data model.
dataMode = "COPYALL"
Copies all fields directly from the input data streams Any required
fields not found on an input stream will be set to zero.
dataMode = "SSTDATA"
SSTDATA mode assumes the only field in the input stream is SST.
It also assumes the SST is in Celsius and must be converted to Kelvin.
All other fields are set to zero except for ocean salinity, which
is set to a constant reference salinity value.
Normally the ice fraction data is found in the same data files that
provide SST data to the data ocean model. They are normally found in
the same file because the SST and ice fraction data are derived from
the same observational data sets and are consistent with each other.
to the data ocean model. They are normally found in the same file
because the SST and ice fraction data are derived from the same
observational data sets and are consistent with each other.
dataMode = "IAF"
IAF is the interannually varying version of SSTDATA
dataMode = "SOM"
SOM ("slab ocean model") mode is a prognostic mode. This mode
computes a prognostic sea surface temperature and a freeze/melt
potential (surface Q-flux) used by the sea ice model. This
calculation requires an external SOM forcing data file that includes
ocean mixed layer depths and bottom-of-the-slab Q-fluxes.
Scientifically appropriate bottom-of-the-slab Q-fluxes are normally
ocean resolution dependent and are derived from the ocean model output
of a fully coupled CCSM run. Note that while this mode runs out of
the box, the default SOM forcing file is not scientifically
appropriate and is provided for testing and development purposes only.
Users must create scientifically appropriate data for their particular
application. A tool is available to derive valid SOM forcing.
Set by the xml variable DOCN_MODE in env_run.xml
Currently, DOCN_MODE can be [prescribed,som,interannual,null]
If DOCN_MODE is prescribed, datamode will be set to SSTDATA
If DOCN_MODE is interannual, datamode will be set to IAF
If DOCN_MODE is som , datamode will be set to SOM
If DOCN_MODE is sst_aqup[n], datamode will be set to SST_AQUAP
If DOCN_MODE is som_aqup[n], datamode will be set to SOM_AQUAP
If DOCN_MODE is null, datamode will be set to NULL

array (up to 30 elements) of delta time ratio limits placed on the
time interpolation associated with the array of streams. this real
value causes the model to stop if the ratio of the running maximum
delta time divided by the minimum delta time is greater than the
dtlimit for that stream. for instance, with daily data, the delta
time should be exactly one day throughout the dataset and the computed
maximum divided by minimum delta time should always be 1.0. for
monthly data, the delta time should be between 28 and 31 days and the
maximum ratio should be about 1.1. the running value of the delta
time is computed as data is read and any wraparound or cycling is also
included. this input helps trap missing data or errors in cycling.
to turn off trapping, set the value to 1.0e30 or something similar.
