The 4th International Workshop on Equatorial Plasma Bubbles (EPB-4) will 
be hosted by the National Institute for Space Research (INPE) in São 
José dos Campos, São Paulo, Brazil, from 14 to 18 September 2026.

EPB-4 will provide an international forum for researchers, students, and 
professionals to exchange ideas, present recent results, and foster

workshop will feature:

  * In-depth discussions on the latest observational techniques,
    including satellite missions, ground-based instrumentation, and
    multi-instrument networks;
  * Advances in coupled models and numerical simulations addressing EPB
    seeding, growth, and variability;
  * Emerging approaches for forecasting EPBs using artificial
    intelligence and machine learning;
  * Analyses of the impacts of EPBs on GNSS positioning, satellite
    communications, and space weather services;
  * Opportunities to strengthen international collaboration and promote
    new research initiatives.

We strongly encourage you to submit your contribution and share your 
latest results with the community.
