This paper discusses the possibilities for using the non-scientific Visual Monitoring Camera (VMC) to contribute to this scientific objective of the Mars Express mission, complementing and supporting the data obtained from the scientific payload. The contribution of VMC is that it can image the planet with a large field of view, providing the context for the other experiments which operate at lower altitudes, close to the pericenter. The VMC data would also allow providing useful information such as cloud altitude (thanks to the shadow) morphology, relative reflectivity and dynamics. These are important parameters in the characterization of the CO2 cloud population.
