AB: The solar community will soon have the unprecedented opportunity to combine both white-light and EUV/X-ray data from 3 simultaneous viewpoints. A new framework is presented that uses all available data for simultaneous determination of 3D temperatures and densities at macro-scales, and multi-thermal distributions and filling factors at micro-scales. The method is based on the combination of standard differential emission measure (DEM) techniques and solar rotational tomography (SRT), which we refer to as differential emission measure tomography (DEMT). DEMT retains the full 3D spatial resolution of SRT while simultaneously providing information about unresolved multi-thermal structures, as is customary with DEM. When combined with white-light tomography, DEMT will allow determination of filling factors, thus giving the community access to a vast amount of 3D information about the state of the corona at a broad range of spatial scales. DEMT simulations using the Atmospheric Imaging Assembly (AIA) bandpasses are presented, and implications for STEREO are discussed.
