A crucial step for understanding the origin of the high temperatures in the upper atmosphere is an accurate description of the energy transport. Current studies on the energy flux in the solar atmosphere mainly focus on the vertical electromagnetic flow through the photosphere, ignoring the possible Poynting flux’s contributions to local heating. This study used observational data from Sunrise/IMaX and Bifrost simulations to analyse the electromagnetic energy flux of the lower atmosphere. Based on a simulated quiet Sun atmosphere, we found that only a small fraction of the Poynting energy flows upwards in the photosphere. See more at https://espos.stream/2022/06/09/Silva/.
