Abstract Coronal mass ejections (CMEs) play a significant role in space weather. In order to evaluate space weather effects, it is important to understand the origin of CMEs in the solar atmosphere. Among various proxies for CMEs in the low corona, the coronal dimming observed as intensity deficit in extreme ultraviolet (EUV) or soft X-ray wavelengths is thought to be the most reliable observable. We examine dimmings detected automatically by Solar Demon in images taken by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory (SDO), and associate strong dimmings with CMEs, flares and EUV waves. The association rate of dimmings with either CMEs or flares is about 75%, and that with EUV waves is about 35%. We also discuss the complementary use of EUV irradiance data, for example, from the Extreme Ultraviolet Experiment on board SDO to isolate dimmings. This may have implications in detecting CMEs from stars.
