How are the atmospheric dust variations and dust storms taken into account ? What about solar variability ?

Eight combinations of dust and solar scenarios are available in the database because these are the two forcing that are highly variable from year to year.

Figure 1: A typical temperature profile observed by radio-occultation (thick solid line, february 1998, $L_s=271^o$, $11.7^o$S-$155^ o$E, local time : 4:30) compared to temperature profiles predicted by the database at the same time and location. Profiles from the ``MY24'' scenario are usually very close to the MGS observations, whereas the ``Warm'' and ``Cold'' scenarios yield warmer and colder temperatures profiles in the lower atmosphere, respectively.
