MITgcm_ocean works with versions of DART before Manhattan (9.x.x) and has yet to be updated. If you are interested in
MITgcm_ocean with more recent versions of DART, contact DAReS staff to assess the feasibility of an update.
Until that time, you should consider this documentation as out-of-date.
trans_pv_svis responsible for converting the ocean model ‘snapshot’ files to a DART ‘initial conditions’ file. In order to do that, the valid time for the snapshot files must be calculated from several pieces of information: the filename contains a timestep index, the
&PARM03namelist contains information about the amount of time per timestep, and the
&CAL_NMLnamelist contains the start time. Additionally, the grid characteristics must be read from
&PARM04. Consequently, the files

input.nmlare needed in addition to the snapshot files.

This program has no namelist of its own, but some of the underlying modules require namelists. To avoid duplication and, possibly, some inconsistency in the documentation, only a list of the required namelists is provided here, with a hyperlink to the full documentation for each namelist.
