Lightning channels promote energy exchange between plasma and surrounding environment generating a plethora of impacts in the atmosphere and to society. In recent years, substantial instrumentation advances have been made in optical, radio-frequency, and energetic radiation imaging of the lightning channels' initiation, propagation, and attachment to ground structures, as well as the return stroke and the subsequent processes taking place inside its decaying channels. Additionally, during the next decade the field should see an explosive growth in the development and use of computational models of lightning and its multi-spectral emissions. We seek abstracts on natural and laboratory observations, modeling, and theoretical efforts dedicated to advancing our community’s understanding of lightning physics.</div><div class=""><br class=""></div><div class="">Location: AGU25 will take place this coming December 15-19 in New Orleans, LA, USA</div><div class=""><br class=""></div><div class=""><b class="">Submit an abstract to this session:</b> <a href="https://agu.confex.com/agu/agu25/prelim.cgi/Session/247554" class="">https://agu.confex.com/agu/agu25/prelim.cgi/Session/247554</a></div><div class=""><br class=""></div><div class=""><b class="">Abstract submission deadline:</b> Wednesday, July 30, 2025, at 23:59 Eastern Time. </div><div class=""><br class=""></div><div class="">Sincerely, the Conveners:</div><div class="">Caitano da Silva, New Mexico Tech</div><div class="">Julia Tilles, Sandia National Labs</div><div class="">Adonis Leal, New Mexico Tech</div><div class=""><br class=""></div><div class="">All Atmospheric & Space Electricity sessions can be found here: <a href="https://agu.confex.com/agu/agu25/prelim.cgi/Program/4770" class="">https://agu.confex.com/agu/agu25/prelim.cgi/Program/4770</a></div>
