             abstract = "We carry out an analysis of the mass that is evacuated from three 
                         coronal dimming regions observed by the Atmospheric Imaging 
                         Assembly (AIA) on board the Solar Dynamics Observatory. The three 
                         events are unambiguously identified with white-light coronal mass 
                         ejections (CMEs) that are associated in turn with surface activity 
                         of diverse nature: an impulsive (M-class) flare, a weak (B-class) 
                         flare, and a filament eruption without a flare. The use of three 
                         AIA coronal passbands allows applying a differential emission 
                         measure technique to define the dimming regions and identify their 
                         evacuated mass through the analysis of the electronic density 
                         depletion associated with the eruptions. The temporal evolution of 
                         the mass loss from the three dimmings can be approximated by an 
                         exponential equation followed by a linear fit. We determine the 
                         mass of the associated CMEs from COR2 data. The results show that 
                         the evacuated masses from the low corona represent a considerable 
                         amount of the CME mass. We also find that plasma is still being 
                         evacuated from the low corona at the time when the CMEs reach the 
                         COR2 field of view. The temporal evolution of the angular width of 
                         the CMEs, of the dimming regions in the low corona, and of the 
                         flux registered by GOES in soft X-rays are all in close relation 
                         with the behavior of mass evacuation from the low corona. We 
                         discuss the implications of our findings toward a better 
                         understanding of the temporal evolution of several parameters 
                         associated with the analyzed dimmings and CMEs.",
