Simulations of the HDO cycle with LMD Mars GCM

We present here simulations of the HDO cycle on Mars, using the LMD Mars GCM. They show the water and HDO cycles, following the reimplementation of tracers related to HDO in the model. In these simulations, the cloud formation is done assuming a simplified scheme, without the details of the condensation nuclei. Clouds are not radiatively active. Two dust scenarios are available: one for the climatology scenario (representative of an average year on Mars), one for the Martian Year 34, during which a global dust storm occured. There are two types of files: one contains column integrated variables, useful for seasonal study. The other are variables rescaled by pressure levels. Finally a file containing the area of each column of the GCM is provided, for example for planetary average computations.
