We recently extended the differential emission measure tomography (DEMT) technique to be applied to the six iron bands of the Atmospheric Imaging Assembly (AIA) instrument aboard the Solar Dynamics Observatory (SDO). DEMT products are the 3D reconstruction of the coronal emissivity in the instrument?s bands, and the 3D distribution of the local differential emission measure, in the height range 1.0 to 1.25 R⊙ . We show here derived maps of the electron density and temperature of the inner solar corona during the rising phase of solar cycle 24. We discuss the distribution of our results in the context of open/closed magnetic regions, as derived from a global potential field model of the same period. We also compare the results derived with SDO/AIA to those derived with STEREO/EUVI.
