Based on measurements of the CACTUS accelerometer it has been found that during the recovery phase of geomagnetic disturbances the models are unable to describe properly the total density changes in the equatorial thermosphere. Introducing the geomagnetic activity index Dst instead of Kp as a model input parameter gives a much better description of the measurements. The residuals show a diurnal dependence, hinting partly at model errors in the diurnal effect (though MSIS 86 is much better than DTM in this respect), partly at a diurnal term in the geomagnetic effect.
