<p class="MsoNormal">We are pleased to announce a 1-day workshop “System-Scale Data Analysis to Resolve Thermospheric Joule Heating”, to be held at the British Antarctic Survey (Cambridge, UK) on Friday the 27<sup>th</sup> April 2017.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The aim of this workshop is to give a forum for discussing of the interdisciplinary utility of data-driven analytical techniques, and the best ways to harness the potential of the available large datasets which are driving advances in near-Earth
space research. The specific focus of the workshop is on the intrinsically interdisciplinary problem of resolving Joule heating – the transfer of energy from electrical currents in the ionosphere to the neutral particles of the upper atmosphere.<o:p></o:p></p>

<p class="MsoNormal">Note that financial support is available for attending postgraduate students. Abstract submission will open in early 2018.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">To enjoy the benefits of an improved description of Joule heating and to improve predictions of its impact, we must understand its components – ionospheric electric field, conductivity and current flow – and the solar, magnetospheric and
thermospheric factors which drive them. These improvements require systems-level (global) analyses, spanning the complex and strongly coupled solar-terrestrial environment. The increasing availability of large ground-based and satellite datasets, such as
AMPERE, SuperDARN and SuperMAG which span multiple years (even multiple solar cycles) with often excellent geographic coverage provides an unprecedented set of complementary observations to achieve this.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Analytical techniques from the disciplines of statistics, machine learning and information theory are driving new discoveries of spatiotemporal trends and interdependencies in solar-terrestrial system phenomena. We see a need to communicate
the use of these techniques to the solar-terrestrial community. We aim to foster discussion on new and existing techniques which provide state-of-the-art descriptions of the Joule heating, its causative electrodynamic components, and the associated thermospheric
response. In particular, we seek out approaches which exploit all available data, rather than focusing on single instruments, epochs, or phenomena. Contributions which improve the understanding of coupling between systems and thus improve the nowcasting, forecasting
or hindcasting of Joule heating phenomena are especially welcome.<o:p></o:p></p>
