Space-based measurements provide global coverage at all longitudes and local times, allowing the separation of magnetic signals originating in the core, lithosphere, ionosphere, and magnetosphere. This session invites presentations on upcoming satellite missions designed for geomagnetic observations, as well as the use of existing and future satellite datasets to advance our capabilities for modeling all sources of the geomagnetic field.</div><div><br></div><div><b>and join our confirmed <font color="#0433ff">invited speakers</font></b>:</div><div><b><font color="#0433ff"><br></font></b></div><div><b><font color="#0433ff">Nicolas Gillet</font></b>, Université Grenoble Alpes, Université Savoie Mont Blanc, IRD, UGE, CNRS, France</div><div><b><font color="#0433ff">Jesper Gjerloev</font></b>, Applied Physics Laboratory, Johns Hopkins University, Laurel, MD, USA</div><div><b><font color="#0433ff">Alexander Grayver</font></b>, Institut für Geophysik und Meteorologie, Universität zu Köln, Deutschland</div><div><br><b><font color="#ff2600">Abstract submission and details</font></b>: <a href="http://www.iugg2023berlin.org/abstract-submission">www.iugg2023berlin.org/abstract-submission</a></div><div><br><b>Online submission FINAL deadline: <font color="#ff2600">21 February 2023</font>.</b><br><br></div><div>Hoping to see you there !</div><div><br></div><div>Best regards,<br><br></div><div>Patrick Alken (co-convenor)</div><div>Gauthier Hulot (convenor)</div></div></div></div></div></div></div><br></body></html>
