The solar corona is structured by the magnetic field in the form of loops or flux tubes. Depending on the relation between the plasma characteristics of each loop and its neighbors, these can be observationally individualized at certain wavelengths, as in active regions EUV images. During periods of minimum solar activity or in the quiescent corona (outside active regions), density and temperature inhomogeneities between loops and their surroundings are relatively low, making them not easily distinguishable in EUV images. Using differential emission measure tomography, combined with a global potential model of the coronal magnetic field, it is possible to characterize the physical parameters of the plasma along loops built from field lines obtained with the magnetic model. In this work, we use a tomographic reconstruction of the Carrington rotation 2082 to analyze statistically the thermodynamic properties of coronal loops. We reconstructed representative loops for different These results are compared with the 1D model, Hydrodynamics and Radiation Code (HYDRAD), for constant or impulsive heating regimes.
