 \paragraph{Inputs/outputs} Large-Eddy Simulations need four input files \ttt{input\_coord}, \ttt{input\_sounding}, \ttt{input\_more}, \ttt{input\_therm} which define initial pressure, temperature, density, winds profiles at the location/season for which simulations are run, along with information about this location/season. Typical files are available upon request, or you might simply build your own profiles using the Mars Climate Database (see the sample \ttt{scilab} script \ttt{wrf\_sounding.sci} in \ttt{\$MMM/SIMU/RUN}). Examples for \ttt{input\_*} files are provided in \ttt{\$MMM/SRC/LES/modif\_mars/DEF} and correspond to the cases run in the study by \textit{Spiga et al.} [2010].

+Using the most recent physical parameterizations means using a version of the LMD Martian Mesoscale Model that is still under development (thus experimental). It is therefore recommended to contact developers to run simulations in this mode.

+\sk
+For advanced users who learnt with the LMD team how to use the new physical parameterizations, here are a few differences with the physical parameterizations natively provided with the LMD Martian Mesoscale Model that must be kept in mind
+\begin{finger}
+\item a folder \ttt{LMDZ\_MARS} containing the latest sources of the Mars LMD GCM must be located in the same repository which contains \ttt{MESOSCALE} (easy to do with SVN)
+\item GCM runs used to produce initial and boundary conditions for the mesoscale model must be done in \ttt{MESOSCALE/LMDZ.MARS.new}
+\item \ttt{makemeso} must be used with option \ttt{-p}
+\item the \ttt{callphys.def} file is different
+\item modifying the \ttt{datafile.h} is not necessary anymore, this can be done in \ttt{callphys.def}
+\item an additional \ttt{run.def} file is needed
+\item the number of scatterers must be given when compiling, standard simulation uses 1 scatterer (2 is used for radiatively active water ice clouds)
+\item in \ttt{namelist.input}, the soil model must set to 18 levels
+\item additional \ttt{mars} modes can be accessed (e.g. for interactive dust or the radiative effect of clouds)
+\item if \ttt{init\_TI} is modified, \ttt{real.exe} must be run again (because of subsurface modeling)
+\item a varying map for surface roughness~$z_0$ can be used -- or a constant value can be set with \ttt{init\_Z0} in \ttt{namelist.input} (if there is a problem, the old reference of 1cm is chosen)
+\item (versions later than late 2013) the model does not need to be recompiled if the number of tracers is changed
+\item (experimental) cases with tracers and water cycle should use \ttt{diff\_6th\_opt = 0} for better stability
+\end{finger}
