<p>Dear Colleagues,<br>
<br>
On behalf of the Local Organizing Committee, we are pleased to
invite the global scientific community to participate in the <b>4th
International Workshop on Equatorial Plasma Bubbles (EPB-4)</b>,
to be hosted by the <b>National Institute for Space Research
(INPE)</b> in São José dos Campos, São Paulo, Brazil, <b>from
14 to 18 September 2026</b>.<br>
<br>
The EPB-4 workshop aims to provide an international forum for
researchers, students, and professionals to exchange ideas,
present recent results, and foster collaborations in the field of
Equatorial Plasma Bubble research. The main highlights of EPB-4
include:<br>
<br>
</p>
<ul>
<li>Promoting in-depth discussions on the latest observational
techniques for monitoring Equatorial Plasma Bubbles (EPBs),
including upcoming satellite missions, advanced ground-based
sensors, and multi-instrument networks</li>
</ul>
<ul>
<li>Highlighting recent progress in coupled models and numerical
simulations to advance the understanding of the mechanisms
governing EPB seeding, growth, and variability</li>
</ul>
<ul>
<li>Enhancing forecasting capabilities by integrating artificial
intelligence and machine learning with observational and
modeling data</li>
</ul>
<ul>
<li>Examining the societal and technological impacts of EPBs on
GNSS positioning, satellite communications, and space weather
services</li>
</ul>
<ul>
<li>Fostering international collaboration and stimulating new
research initiatives dedicated to EPB science and its
applications</li>
</ul>
<p><br>
<b>Workshop registration will be open from 14 February to 14 May
2026.</b></p>
<p><br>
Additional information regarding registration, abstract
submission, and the scientific program is available on the
official workshop webpage:<br>
