<div dir="ltr"><div>Dear Colleagues,<br><br></div>We cordially invite you to present your research at the <span class="">26th General Assembly of the International Union of Geodesy and Geophysics in the Inter-Association Joint Session JG2: Modelling the Atmosphere and Ionosphere by Space Measurements:<br></span><span style="font-family:comic sans ms,sans-serif"><font><span lang="EN-CA"><br>Space measurements of various types play a
fundamental role in our growing understanding of the various processes in the Earth’s
atmosphere, especially the coupling of its different layers. The different
disciplines of geodesy, aeronomy, geomagnetism and meteorology contribute and
benefit in a multi-disciplinary way. They involve observing satellite systems, whether
dedicated or not, and the development and application of models and techniques
to treat, assimilate, represent and interpret those measurements. </span></font></span><span style="font-family:comic sans ms,sans-serif"><font>
</font></span><p class="MsoNormal"><span style="font-family:comic sans ms,sans-serif"><font><span lang="EN-CA"></span></font></span><span style="font-family:comic sans ms,sans-serif"><font><span lang="EN-CA">We encourage the submission of papers
dealing with methodology, applications, as well as with inter-comparisons and
validation.<span> </span>They include the
assessment, validation and discussion of current and future satellite systems;
the modelling of atmospheric corrections for geodesy; GNSS-based atmospheric
sounding; advancements in the modelling of the atmosphere, including
tomographic techniques; modelling and interpretation and modeling of space
weather and its coupling with the terrestrial weather; assimilation of
measurements into numerical models; and use of long-term space-based monitoring
and numerical models for a variety of applications, including terrestrial and
space climate. We accept contributions dealing with global and regional scales.</span></font></span><span style="font-family:comic sans ms,sans-serif"></span></p><p class="MsoNormal"><br><span lang="EN-CA"></span></p><p class="MsoNormal"><span lang="EN-CA">The 26th IUGG General Assembly will be held at Prague, Czech Republic 22 June-2 July 2015, and the abstract deadline is 31 January 2015.
