We apply the Differential Emission Measure Tomography (DEMT) technique to STEREO/EUVI and SDO/AIA data obtained during the rising phase of the solar cycle 24. As a result we obtain the three-dimensional (3D) differential emission measure in the height range 1.00 to 1.25 Rsun. We use that information to construct 3D maps of the coronal electron density and temperature. We discuss the 3D distribution of our results in the context of a global potential magnetic field model of the same period. We also discuss the utilization of DEMT results as constraint for the modeling of the solar corona, and the impact of the new information gained by using the six coronal bands of SDO/AIA respect to previous tomographic results based on the three coronal bands of STEREO/EUVI.
