DART Documentation Main Index
ncommas_to_dart is the program that reads a ncommas
restart file (usually ncommas_restart.nc) and creates
a DART state vector file
(e.g. perfect_ics, filter_ics, ... ).
The list of variables used to create the DART state vector are specified in the ncommas_vars.nml file.
Conditions required for successful execution of ncommas_to_dart:
Since this program is called repeatedly for every ensemble member, we have found it convenient to link the ncommas restart files to the default input filename (ncommas_restart.nc). The default DART state vector filename is dart_ics - this may be moved or linked as necessary.
This namelist is read from the file input.nml. Namelists start with an ampersand '&' and terminate with a slash '/'. Character strings that contain a '/' must be enclosed in quotes to prevent them from prematurely terminating the namelist.
&model_nml ncommas_restart_filename = 'ncommas_restart.nc'; assimilation_period_days = 1, assimilation_period_seconds = 0, model_perturbation_amplitude = 0.2, output_state_vector = .true., calendar = 'Gregorian', debug = 0 /
&ncommas_to_dart_nml ncommas_to_dart_output_file = 'dart_ics' /
ncommas_to_dart_nml and model_nml are always read from a file called input.nml. The full description of the model_nml namelist is documented in the NCOMMAS model_mod.

ncommas_vars_nml is always read from a file called ncommas_vars.nml.

none - all error messages come from modules that have their own documentation.
