cam_to_dart is the program that reads a CAM
restart file (usually caminput.nc) and creates
a single DART output/restart file
(e.g. perfect_ics, filter_ics, ... ). If you have
multiple input files, you will need to rename the output files as you create them.
The list of variables extracted from the CAM netCDF file and conveyed to DART is controlled by the set of input.nml &model_nml:state_names_* variables. The date and datesec variables in the CAM netcdf file are used to specify the valid time of the state vector. The time may be changed with the restart_file_tool if desired.
Some CAM restart files are from climatological runs and have a valid time that predates the use of the Gregorian calendar. In such instances, the year component of the original date is changed to be a valid Gregorian year (by adding 1601). A warning is issued to the screen and to the logfile. Please use the restart_file_tool to change this time.
Conditions required for successful execution of cam_to_dart:
Since this program is called repeatedly for every ensemble member, we have found it convenient to link the CAM restart files to the default input filename (caminput.nc). The default DART output 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.
&cam_to_dart_nml cam_to_dart_input_file = 'caminput.nc', cam_to_dart_output_file = 'dart_ics', /
