Аннотация: Storm-time precipitation of energetic electrons at high latitudes dis-turbs globally the thermosphere-ionosphere system. Recent years, unusual dynam-ic's of ionospheric response was found during major magnetic storms. The dynam-ics resulted mainly from anomalous expansion and displacement of the precipita-tion region toward equator because of acceleration in the secular variation of the geomagnetic field. A revision of the precipitation location and power is required in order to adjust the existing first principles global coupled thermosphere-ionosphere models to the observations of unusual disturbances in the ionosphere and thermo-sphere. In the first time, we combine low-energy spectra of electrons measured by the DMSP satellites in the auroral region with high-energy spectra observed by the POES satellites in the outer radiation belt. This combination allows specifying of the total energy deposition of electron precipitations. The location of the precipita-tion region is determined from both LEO satellite observations and magnetic data on the auroral electrojet acquired from the global network of ground based magne-tometers. This approach gives new insight to the problem of magnetosphere-ionosphere coupling and help to improve the prediction of space weather models.
