<p>We studied&#160;43 coronal dimming events associated with Earth-directed&#160;coronal mass ejections (CMEs)&#160;that were&#160;observed in quasi-quadrature by&#160;the SDO and STEREO satellites.&#160;We derived the properties of the dimmings as observed above&#160;the limb by STEREO EUVI, and compared&#160;them&#160;with the mass and speed of the associated CMEs. The&#160;unique satellite constellation&#160;allowed us to compare our&#160;&#64257;ndings with the results from Dissauer et al.&#160;(2018, 2019), who studied these events observed against the solar disk&#160;by SDO&#160;AIA. Such statistics is done for the&#160;&#64257;rst time and confirms the close relation between characteristic dimming and CME parameters for the off-limb viewpoint.&#160;We&#160;&#64257;nd that the dimming areas are typically larger for off-limb observations (mean value of 1.24&#177;1.23&#215;10<sup>11</sup>&#160;km<sup>2</sup>&#160;against 3.51&#177;0.71&#215;10<sup>10</sup>&#160;km<sup>2</sup>&#160;for on-disk), while&#160;the&#160;decrease in the total extreme ultraviolet intensity is similar (c=0.60&#177;0.14). The off-limb dimming areas and brightnesses are&#160;strongly correlated&#160;with the CME mass (c=0.82&#177;0.06 and 0.75&#177;0.08), whereas the dimming area and brightness change rate correlate with the CME speed (c&#8764;0.6). Our&#160;&#64257;ndings suggest that coronal dimmings have the potential to provide early estimates of the Earth-directed CMEs parameters, relevant for space weather forecasts, for satellite locations at both L1 and L5.</p>
