  \begin{verbatim}
  nIter0=0,

  Sets the starting time for the model internal time counter.
  When set to non-zero this option implicitly requests a
  checkpoint file be read for initial state.
  By default the checkpoint file is named according to
  the integer number of time step value \verb+nIter0+.
  The internal time counter works in seconds. Alternatively,
  \verb+startTime+ can be set.

  Sets the time step number at which this simulation will terminate.
  At the end of a simulation a checkpoint file is automatically
  written so that a numerical experiment can consist of multiple
  stages. Alternatively \verb+endTime+ can be set.

  This line specifies the name of the file from which the domain
  bathymetry is read. This file is a two-dimensional ($x,y$) map of
  depths. This file is assumed to contain 32-bit binary numbers
  giving the depth of the model at each grid cell, ordered with the x
  coordinate varying fastest. The points are ordered from low coordinate
  to high coordinate for both axes. The units and orientation of the
  depths in this file are the same as used in the MITgcm code. In this

  of $<0m$ indicates open ocean.

 Line 244 
 meridWindFile='trenberth_tauy.bin'
    These lines specify the names of the files from which the x- and y-
    direction surface wind stress is read. These files are also
    three-dimensional ($x,y,time$) maps and are enumerated and formatted
    in the same manner as the bathymetry file.
