For moderate use : the World Wide Web site.
For anyone having access to internet, This World Wide Web site has been developed at LMD. In adition to a complete documention, this interactive site offer a direct and convenient access to the data in a variety of graphical and numerical formats. However, the variability models are not available on the web-site.
For intensive or precise work : the DVD-ROMs
The new MCD V4.1 is available for distribution on a DVD-ROM containing the data files (in NetCDF format) and access software including variability models to account for the sub-grid scale and day-to-day variations of the martian atmosphere + high resolution surface pressure prediction.
The softwares are written in very portable Fortran 77
Unix and Linux prefered, but can be used on windows
IDL and Mathlab interface subroutines are now provided
C interface example
