1. AOGS Session: Coupling Between Inner-magnetospheric, Ionospheric, and Thermospheric Particle Populations, abstract deadline: 28 Feb 2025.

From: Dedong Wang, GFZ Potsdam, <dedong at gfz.de>

https://meetingorganizer.copernicus.org/EGU25/session/53618

Abstract deadline: 28 Feb 2025

Subject: Coupling Between Inner-magnetospheric, Ionospheric, and Thermospheric Particle Populations

Conveners: Dr Dedong Wang (GFZ German Research Centre for Geosciences), Dr Alexander Drozdov (University of California, Los Angeles), Prof Yoshizumi Miyoshi (Nagoya University), Dr Rongxin Tang (Nanchang University), Prof Chao Yue (Peking University)

Session Description: The Earth's inner magnetosphere contains different charged particle populations, including the Van Allen radiation belts, ring current, and plasmasphere, whose energy ranges from eV to several MeV. The interplay among these charged particles provides feedback mechanisms that couple these populations. For instance, ring current particles generate various waves, such as EMIC and chorus waves, essential in the dynamic evolution of radiation belt particles through wave-particle interactions. These interactions can accelerate ring current electrons to relativistic energies, while plasmaspheric particles can affect these processes.

Precipitation of ring current and radiation belt particles can significantly impact the ionosphere and thermosphere by changing ionospheric conductivities and serving as sources of nitric oxide in the lower thermosphere. Conversely, up-flows of ionospheric particles can affect plasma dynamics within the inner magnetosphere. A comprehensive understanding of these coupling processes is crucial for advancing space weather models and deepening our fundamental knowledge of Earth's near-space environment.

We invite presentations on recent progress related to these coupling processes. Contributions from all relevant fields, including theoretical studies, numerical modelling, and observations from satellite and ground-based missions, are welcome. This includes but is not limited to, satellite and ground-based mission analysis from the Van Allen Probes, ARASE, THEMIS, MMS, GOES, Cluster, SWARM, DSX, SuperDARN, CubeSats, magnetometers, optical imagers, and IS-radars.

From: Simone Di Matteo, The Catholic University of America / NASA-GSFC, <dimatteo at cua.edu>

Subject: Course on “Cross-scale coupling of Heliophysics Systems” 12-16 May, 2025 (SECOND ANNOUNCEMENT).

A Course on “Cross-scale coupling of Heliophysics Systems”, directed by Prof. Ioannis Daglis (University of Athens, Greece), Simone Di Matteo (Catholic University of America; NASA –Goddard Space Flight Center, USA), and Marco Romoli (University of Florence, Italy) will be held in L’Aquila, Italy, 12-16 May, 2025. The course is organized in cooperation with the Consorzio “Area di Ricerca in Astrogeofisica”. The school will serve as a comprehensive introduction to the emerging need to understand the inter-connectivity of heliophysics systems mediated through cross-scale processes. The lectures will cover the main heliophysics regions discussing the corresponding macro (system size) scales, micro (kinetic) scales, and the mesoscale processes mediating cross-scale coupling, as well as discuss the interconnection between the different systems. This course aims at providing an overview of cutting-edge fundamental research of “system of systems” phenomena in heliophysics in terms of observations and modeling capabilities. A particular section will be dedicated to highlighting the current coordination and networking efforts among the international community on this topic.This school is addressed to graduate students, young scientists as well as undergraduates in heliophysics, space plasma physics, planetary sciences, or related fields. Early-career stage professionals are invited to apply as well. Applications are due before 16 March, 2025.

Applications will be evaluated by the Board of Directors of the School, after which all applicants will be notified by email. The registration fee of 1000 Euros includes board and lodging. The payment conditions will be communicated via email to applicants who receive positive evaluation.

From: Dudok de Wit, Thierry, University of Orléans, <ddwit at cnrs-orleans.fr>

At the university of Orléans we have an open position for a 3-year PhD on *Fine structure of type III solar radio bursts*, which is about the investigation of signatures of wave generation processes in the solar wind using observations from Parker Solar Probe and Solar Orbiter. Solar radio bursts have recently received considerable attention because of the interaction of the energetic particles that generate them with the local medium. This PhD project seeks to explore and better understand the underlying physical processes.
The three supervisors of this multidisciplinary project are Säm Krucker (SSL Berkeley, and Univ. of Applied Sciences Northwestern Switzerland), and Vladimir Krasnoselskikh & Thierry Dudok de Wit (LPC2E, Orléans). Candidates should have a strong background in space science and be fluent in data analysis. Expertise in plasma physics is an asset. Applications must be submitted by 14 March 2025 via the CNES website: https://recrutement.cnes.fr/fr/annonce/3428731-25-288-fine-structure-of-type-iii-solar-radio-bursts-45100-orleans .

Subject: Second Announcement: NOW OPEN - European Space Weather Week 2025 Call for Convening Sessions and Discussion Meetings, 27th - 31st October 2025, Umeå, Sweden.

European Space Weather Week (ESWW) 2025 will be held in Umeå, Sweden from 27th - 31st October in a hybrid format. The overarching theme for ESWW2025 is ‘Technological expansion of the Arctic: the new frontiers of space weather’.

The ESWW conference is an excellent opportunity for people from all over the world to gather and discuss the most recent insights in space weather and space climate, and to address the emerging challenges and impacts. Science, observations, data exploitation, data standards and metadata, service development, operational models, engineering and industrial needs are all important aspects of the field that are addressed.

One of the strengths of ESWW is that participants can contribute significantly to its content through Parallel Sessions, Plenary Sessions and Topical Discussion Meetings (TDMs). The ESWW Programme Committee (PC) and Local Organising Committee (LOC) are pleased to announce that the call for the convening of these sessions is now open with the following closing dates: Plenary and Parallel Sessions - 21st March 2025, Topical Discussion Meetings (TDMs)- 4th April 2025.

A short synopsis of each element is given below. More information is available on the ESWW2025 website:

https://esww.eu/calls/parallel-and-plenary-sessions. This year the ESWW organisers are using an instance of the Indico system provided by E-SWAN (the European Space Weather and space climate AssociatioN):
https://events.spacepole.be/e/esww2025

Those submitting proposals will first need to register on the Indico system before they can submit a session/TDM proposal. Each user can submit one proposal in each category; plenaries, parallel sessions and TDMs. Individuals can be conveners on more than one proposal of any given type but should have another convener make the submission in case they have already made another one. If this is not possible they should contact the ESWW2025 LOC: esww2025.loc at gmail.com
