It is possible to specify some Fortran variables as specific model parameters. Model parameters may be used in sensitivity studies (see Sensitivity to a parameter) and in the adjoint model (see Sensitivity of cost function to parameters). Nothing special is done with parameters with Kalman filtering.
The parameters are fortran variables that should be initialized somewhere
in ‘zinit’. For a variable to be considered as a parameter, it should
be passed as an
argument to the Free_parameters macro. For example if
apar and cpar (from the predator example) are to be considered
as parameters, Free_parameters should be called with:
Free_parameter: apar, cpar;
When used with grid1d models (see Describing 1D gridded model) the inode number may appear in
parenthesis:
Free_parameter: rd(1), rk(2);
