[PEM07-12] Preliminary results of auroral tomography analysis of discrete arcs observed on March 14, 2015
Keywords:aurora, tomography analysis, 3D distribution, ionosphere, EISCAT radar
We apply the auroral tomography method to these data set to reconstruct reliable three-dimensional distribution of the 427.8 nm emission, that will allow us to investigate quantitatively the following subjects; (1) relation between the 427.8 nm emission and electron density enhancement along the field line, (2) spatial distribution of energy of precipitating electrons in the wavy structure, in particular, relation between the energy of precipitating electrons and thickness of discrete arc, (3) relation between motion of the wavy structure and spatial distribution of the ionospheric conductivity, and (4) spatial and temporal variations of energy distribution of precipitating electrons at the auroral breakup. We present preliminary results from the auroral tomography analysis of the discrete arcs.
