3.18.3 Code Configuration
The model configuration for this experiment resides under the directory
verification/tutorial_global_oce_optim/. The experiment files in
code_ad/ and input_ad/ contain the code customizations and parameter
settings. Most of them are identical to those used in the Global Ocean
( experiment tutorial_global_oce_latlon). Below, we describe some of
the customizations required for this experiment.
In ECCO_CPPOPTIONS.h:
- define ALLOW_ECCO_OPTIMIZATION
- define ALLOW_COST, ALLOW_COST_TEMP, and ALLOW_COST_HFLUXM
- define ALLOW_HFLUXM_CONTROL
3.18.3.2 Running-time customizations in input_ad/
- data: note the smaller cg2dTargetResidual than in the
forward-only experiment,
- data.optim specifies the iteration number,
- data.ctrl is used, in particular, to specify the
name of the sensitivity and adjustment files associated to a control
variable,
- data.cost: parameters of the cost functions, in particular
lastinterval specifies the length of time-averaging for the model
temperature to be used in the cost function (3.92),
- data.pkg: note that the Gradient Check package is turned on by
default (useGrdchk=.TRUE.),
- Err_hflux.bin and Err_levitus_15layer.bin are the
files containing the heat flux and potential temperature uncertainties,
respectively.
