\chapter{The physical parameterizations of the Martian model: some references}

\label{sc:phymars}

\section{General}

The Martian General Circulation Model uses a large number of physical
parameterizations based on various scientific theories
and some generated using specific numerical methods.

A list of these parameterizations is given below, along with the most
appropriate
references for each one. Most of these documents can be consulted at:
\verb+http://www-mars.lmd.jussieu.fr/mars/publi.html+.


\paragraph{General references:}
A document attempts to give a complete scientific description of the current
version of the GCM (a version without tracers):

\item  {\it Forget et al.} [1999] (article
published in JGR)

\section{Radiative transfer}

The radiative transfer parameterizations are used to calculate the heating
and cooling ratios in the atmosphere and the radiative flux at the surface.
