CEDAR email: Invitation to ST-22 Session of AOGS2025

Subject: AOGS-2025 Session (ST-22): Advances in Monitoring, Modeling, and
Forecasting Equatorial Plasma Bubbles

Dear Colleagues,

We hope you will consider submitting an abstract to Session ST22 at
AOGS-2025, which will be held in Marina Bay Sands, Singapore from July 27th
to August 1st, 2025 This session brings researchers together to share
perspectives on recent progress in understanding EPB dynamics, their
driving mechanisms, and their impacts on the ionosphere. We welcome
contributions that can help foster discussions on observational techniques,
model simulations, and forecasting approaches for these phenomena.

Session Description:
Equatorial Plasma Bubbles (EPBs) are a major cause of amplitude and phase
fluctuations in GNSS signals, leading impacts to positioning errors, signal
loss, and degraded performance in applications such as ionospheric radio
occultation (RO) at low latitudes. However, with increasing solar activity,
recent observations show that EPBs are now extending more frequently into
mid-latitudes, particularly during geomagnetic storms. This growing impact
of EPBs at mid-latitudes highlights the need for a deeper understanding of
their formation and behavior beyond low-latitude regions. This session aims
to explore advancements in EPB monitoring and modeling, which have revealed
the complexities of EPB formation and development related to wave
disturbances and neutral wind dynamics in the ionosphere. Various
monitoring techniques, including ground-based radar, optical and GNSS
observations, space-based RO, and in-situ measurements, will provide
valuable insights into this topic. Contributions focused on modeling and
data assimilation analysis of the ionosphere are welcomed.

We look forward to your participation in our AOGS session. Please note that
the abstract submission deadline is Tuesday, 18 February 2025 at 23:59 (GMT
+8, Singapore Standard Time)

Sincerely,
Session Conveners:  Shih-Ping Chen, Chi-Yen Lin, Chun-Yen Huang
