Scientific paper

Three points and research directions are discussed: The outstanding problem of identifying the mechanisms of solar atmospheric heating and wind acceleration can be solved only by combining quantitative models that include realistic descriptions of relevant transport processes with observational constraints on the inputs and outputs of these models. Most solar atmospheric heating, with the possible exception of flares, takes place in the chromosphere, emphasizing the importance of identifying the mechanisms of chromospheric heating, which may be important for understanding coronal heating and wind acceleration. Recent modeling leads to the conclusion that the onset of proton magnetization with increasing height in thin magnetic flux tubes triggers the onset of chromospheric network heating by resistive dissipation of Pedersen currents driven by the convection electric field of slow, longitudinal magnetoacoustic waves.
