-\subsection{Simple subsetting of input files via NetCDF attributes}
-
-The extended grids for use with the under-shelf ice cavities will result in redundant rows
-around Antarctica if the ice cavities are not active.  A simple mechanism for subsetting
-input files associated with the extended domains has been implemented to avoid the need to
-maintain different sets of input fields for use with or without active ice cavities.  This
-subsetting operates for the j-direction only and works by optionally looking for and using
-a global file attribute (named: \np{open_ocean_jstart}{open\_ocean\_jstart}) to determine the starting j-row
-for input.  The use of this option is best explained with an example:
-\medskip
-
-\noindent Consider an ORCA1
-configuration using the extended grid domain configuration file: \textit{eORCA1\_domcfg.nc}
-This file define a horizontal domain of 362x332.  The first row with
-open ocean wet points in the non-isf bathymetry for this set is row 42 (\fortran\ indexing)
-then the formally correct setting for \np{open_ocean_jstart}{open\_ocean\_jstart} is 41.  Using this value as
-the first row to be read will result in a 362x292 domain which is the same size as the
-original ORCA1 domain.  Thus the extended domain configuration file can be used with all
-the original input files for ORCA1 if the ice cavities are not active (\np[=.false.]{ln_isfcav}{ln\_isfcav}). Full instructions for achieving this are:
-
-\begin{itemize}
-\item Add the new attribute to any input files requiring a j-row offset, i.e:
-\begin{cmds}
-ncatted  -a open_ocean_jstart,global,a,d,41 eORCA1_domcfg.nc
-\end{cmds}
-
-\item Add the logical switch \np{ln_use_jattr}{ln\_use\_jattr} to \nam{cfg}{cfg} in the configuration
-namelist (if it is not already there) and set \forcode{.true.}
-\end{itemize}
-
-\noindent Note that with this option, the j-size of the global domain is (extended
-j-size minus \np{open_ocean_jstart}{open\_ocean\_jstart} + 1 ) and this must match the \texttt{jpjglo} value
-for the configuration. This means an alternative version of \textit{eORCA1\_domcfg.nc} must
-be created for when \np{ln_use_jattr}{ln\_use\_jattr} is active. The \texttt{ncap2} tool provides a
-convenient way of achieving this:
-
-\begin{cmds}
-ncap2 -s 'jpjglo=292' eORCA1_domcfg.nc nORCA1_domcfg.nc
-\end{cmds}
-
-The domain configuration file is unique in this respect since it also contains the value of \texttt{jpjglo}
-that is read and used by the model.
-Any other global, 2D and 3D, netcdf, input field can be prepared for use in a reduced domain by adding the
-\texttt{open\_ocean\_jstart} attribute to the file's global attributes.
-In particular this is true for any field that is read by \NEMO\ using the following optional argument to
-the appropriate call to \np{iom_get}{iom\_get}.
-
-\begin{forlines}
-lrowattr=ln_use_jattr
-\end{forlines}
-
-Currently, only the domain configuration variables make use of this optional argument so
-this facility is of little practical use except for tests where no other external input
-files are needed or you wish to use an extended domain configuration with inputs from
-earlier, non-extended configurations. Alternatively, it should be possible to exclude
-empty rows for extended domain, forced ocean runs using interpolation on the fly, by
-adding the optional argument to \texttt{iom\_get} calls for the weights and initial
-conditions. Experimenting with this remains an exercise for the user.
