    Magnetic Field Data Correction in Space for Modelling the Lithospheric Magnetic Field

    The Earth’s magnetic field as it is measured by low-Earth orbit satellites such as Swarm and CHAMP results from the superposition of internal and external source fields overlap** in time and in space. The Earth...

    On the Usage of Geomagnetic Indices for Data Selection in Internal Field Modelling

    We present a review on geomagnetic indices describing global geomagnetic storm activity (Kp, am, Dst and dDst/dt) and on indices designed to characterize high latitude currents and substorms (PC and AE-indices an...

    Isolated nighttime substorms and morning geomagnetic Pc5 pulsations from ground-based and satellite (THEMIS) observations

    The analysis results of a complex of phenomena that were develo** in the evening and morning magnetospheric and ionospheric sectors during two events (January 18 and February 19, 2008) are presented. The ana...

    Alfvén: magnetosphere—ionosphere connection explorers

    The aurorae are dynamic, luminous displays that grace the night skies of Earth’s high latitude regions. The solar wind emanating from the Sun is their ultimate energy source, but the chain of plasma physical p...

    Ionospheric Signatures Of Bursty Bulk Flows

    While the plasma convection in the Earth's magnetosphere was for a long timeconsidered to consist mostly of laminar flows with wide spatial extents, about adecade ago the phenomenon of bursty bulk flows (BBFs)...

    Auroral precipitation fading before and at substorm onset: ionospheric and geostationary signatures

    Rapid fading of auroral activity a few minutes before substorm breakup has earlier been analyzed in case-studies. Here we report on a study in which all-sky camera (ASC) and magnetic data over 3 years were exa...

    What can we tell about global auroral-electrojet activity from a single meridional magnetometer chain?

    The AE indices are generally used for monitoring the level of magnetic activity in the auroral oval region. In some cases, however, the oval is either so expanded or contracted that the latitudinal coverage of th...
