\section{Saving the results \label{sec:output} }

GOTM provides an easily extendible interface for storing calculated results.
The main specifications are given via the {\tt output} namelist in
{\tt gotmrun.inp}. The most important member in this namelist is
the integer {\tt out\_fmt}. Changing this variable will select the output format
--- presently ASCII and NetCDF are supported.

In GOTM output is triggered by {\tt do\_output()}
called inside the main integration loop (see \sect{sec:gotm}).
Completely separated from the core of GOTM, a format specific
subroutine is called to do the actual output.  We strongly recommend
to use the NetCDF format --- mainly because it is well established and
save --- but also because a large number of graphical programmes can
read NetCDF. Another reason is the powerful package nco' which
provides some nice programs for manipulating NetCDF files. Information
about how to install and use NetCDF and nco can be found at
\begin{itemize}
\item {\tt http://www.unidata.ucar.edu/packages/netcdf} and
\item {\tt http://nco.sourceforge.net}.
\end{itemize}
