We have recently extended the Differential Emission Measure Tomography (DEMT) technique to be applied to the six iron bands of the Atmospheric Imaging Assemebly (AIA) instrument aboard the Solar Dynamics Observatory (SDO). The AIA based DEMT products are the 3D reconstruction of the coronal emissivity in the instrument's six coronal bands, and the 3D distribution of the local differential emission measure (LDEM), in the height range 1.00 to 1.25 Rsun. Based on the reconstructed LDEM, in this work we show 3D maps of the electron density and temperature of the inner solar corona during the rising phase of solar cycle 24. We discuss the 3D 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 discuss the new information gained with AIA/SDO respect to our previous tomographic results based on the three bands of EUVI/STEREO.
