AbstractIn this paper, we demonstrate that, besides the well-known corpuscular heating of auroral origin, there is another heat source in the equatorial region of the neutral upper atmosphere acting during and after geomagnetic storms as a consequence of the precipitation of ring current ions. The effect of the two sources has been separated on the basis of their induced diurnal variations using measurements from the CACTUS micro-accelerometer. In Almár and Illés-Almár [Adv. Space Res., this issue, 2004, doi:10.1016/j.asr.2003.04.060], the observational facts and our suggestion for the improvement of the CIRA'86 model are summarized to draw the attention of the constructors of the new CIRA model on two effects that are not yet built into the earlier CIRA models. In the present paper, we try to outline the possible physics behind the observational facts necessitating the improvement of the model.
