The conference will take place in Florence, Italy, from 1-9 August 2026. COSPAR-26-C2.1: Gravity Waves and Turbulence in the Middle Atmosphere and Lower Ionosphere, and COSPAR-26-C2.2: Layered Phenomena in the Middle Atmosphere. C2.1: Gravity Waves and Turbulence in the Middle Atmosphere and Lower Ionosphere Gravity waves and turbulence are central to our understanding of the neutral middle atmosphere and ionosphere, yet key questions remain regarding wave generation and propagation, instabilities and wave breaking, secondary wave generation, energy transfer to turbulence, and coupling between atmospheric layers. This session aims to bring together experts working on these topics in the middle atmosphere and lower ionosphere. We welcome theoretical, modelling, experimental, and observational studies related to gravity waves or turbulence in this region. C2.2: Layered Phenomena in the Middle Atmosphere Physical and chemical processes in the Mesosphere and Lower Thermosphere (MLT) give rise to a rich variety of layered structures. These include metal layers formed by meteoric input and space debris, ice-related features such as noctilucent clouds (NLC), radar phenomena such as Polar Mesosphere Summer Echoes (PMSE) and Winter Echoes (PMWE), and dynamically driven structures such as mesospheric inversion layers and turbulent layers. These layers act as tracers of atmospheric dynamics and vertical coupling on timescales from seconds to decades. Recently, metal layers have gained additional relevance as indicators of anthropogenic pollution from reentering space debris. This session invites contributions on topics including middle atmosphere dynamics, long-term trends, solar-cycle effects, vertical coupling processes, and the impact of human activity on MLT composition. We encourage submissions that exploit synergies between different instruments, platforms, and models, and that highlight links between dynamics, chemistry, and space-weather-related impacts. Please submit your abstract via the COSPAR online system, selecting Commission C, Sub-Commission C2, and the appropriate session (C2.1 or C2.2). https://www.cospar-assembly.org/assembly.php Feel free to forward this invitation to colleagues who may also be interested. We look forward to receiving your contribution and to an engaging set of discussions at COSPAR-26.

We invite you to submit contributions to Session G07 ? The High Latitude Atmosphere. Session Description A multidisciplinary and multi-instrument approach, supported by advanced modeling efforts, is essential to advancing our understanding of the high-latitude atmosphere, including the ionosphere, and the broader geospace environment. Addressing some of the most pressing scientific questions in atmospheric and space physics requires collaborative and integrative strategies. Key questions include: 1. How are different atmospheric layers coupled in the polar regions? 2. How does the upper polar atmosphere, comprising the mesosphere, thermosphere, and ionosphere, respond to increased geomagnetic activity and energy input from space? 3. How does the polar atmosphere influence short- and long-term climate variability? Answering these questions will not only enhance our understanding of polar atmospheric processes but also significantly improve insights into global atmospheric dynamics. These research efforts contribute to AGATA (Antarctic Geospace and ATmosphere reseArch), a newly endorsed Scientific Research Programme by SCAR (Scientific Committee on Antarctic Research) and recognized by ICARP IV (Fourth International Conference on Arctic Research Planning) coordinated by the IASC (International Arctic Science Committee) as an open platform for collaboration among scientists and stakeholders. We invite contributions that tackle key scientific challenges in atmospheric and space physics, including whole-atmosphere coupling, the impacts of space weather, and the response of the polar atmosphere to climate variability and change. We especially encourage submissions that present innovative tools, observational methodologies, and interdisciplinary approaches to upper atmosphere (including also ionosphere) and high-latitude research, ranging from advanced ground-based and space-borne instrumentation to emerging modeling techniques such as data assimilation and AI-driven forecasting.

We invite you to submit contributions to Session G14 - Natural and Anthropogenic Sources of Transient Plasmas and Radio Emissions in the Near-Space Environment Session Description: This session focuses on transient plasma phenomena in the near-Earth environment generated by both natural (e.g., micrometeoroids) and anthropogenic (e.g., re-entering objects) sources. Emphasis is placed on the physical processes by which high-speed particles entering or impacting the atmosphere, spacecraft, or planetary surfaces produce dense plasmas, how these plasmas expand and evolve, and how they couple into electromagnetic effects such as collisional electromagnetic pulses (EMPs), electromagnetic ion-cyclotron (EMIC) waves, and other transient wave modes producing distinctive radio and radar signatures. The session invites observational, theoretical, and modeling studies spanning atmospheric and ionospheric meteor events to impact-generated EMPs on spacecraft or planetary surfaces. For micrometeoroids, particular attention is given to entry and impact processes?sputtering, fragmentation, ablation, and ionization?and their influence on derived atmospheric and ionospheric parameters including neutral winds, temperatures, densities, meteor orbits, and masses. We especially encourage contributions on radio and radar detection, plasma diagnostics, and numerical simulations of these highly transient events. Comparative studies of natural versus anthropogenicplasma sources and discussions of their broader implications for space weather, spacecraft charging, space situational awareness, and atmospheric composition are also welcome. URSI also offers a rich program for students and young scientists, including awards and competitions.

Abstract submission deadline on 23 January, 2026. Session Description: Space climate in the Sun-Earth system can be considered as the expected average behaviour of the solar wind and IMF, geomagnetic field, magnetosphere, ionosphere, thermosphere and geomagnetically induced currents (GIC). Space weather is the unexpected short-term changes in the above phenomena. Space weather originates from the Sun as solar eruptions (solar flares and coronal mass ejections or CMEs) and high-speed streams. CMEs flowing through the interplanetary space become interplanetary CMEs (CMEs) cause large changes in the interplanetary space such as shocks and solar energetic particle (SEP) events. The fast solar wind or high-speed streams originating from coronal holes interact with the slow wind ahead, forming corotating interaction regions (CIRs).? The interaction of the ICMEs and CIRs with the Earth?s magnetosphere through magnetic reconnection leads to wave-particle interactions, radio bursts, intense radiation belts, large currents in the magnetosphere and ionosphere, geomagnetic storms/activities, intense auroras, ionosphere-thermosphere storms, large geomagnetically induced currents (GICs), etc. Sometimes space weather becomes severe resulting in extensive societal and economic disruptions by damaging satellite systems, electric power grids, railway traffic systems, radio communication-navigation systems, oil and gas metal pipelines. For example, if a space weather event similar to the 1859 Carrington event occurs at the present time, it results in economic losses up to (estimated) 1-2 trillion US Dollars. Quebec 1989 geomagnetic storm caused a cost of ~13.2 million including system damage and power revenue loss. This session invites contributions on all aspects of space weather studies using ground- and space-based observations, theory and modelling including 10-12 May and 9-10 October 2024 events that caused geomagnetic storms of historical proportions.? ?

The thermal structure of these regions is influenced by numerous energy sources such as solar radiation, chemical, and dynamical processes, as well as forces from both above (e.g., solar and magnetospheric inputs) and below (e.g., gravity waves and atmospheric tides). Solar atmospheric tides, related to global-scale variations of temperature, density, pressure, and wind waves, are responsible for coupling the lower and upper layers of the atmosphere and significantly impact their vertical profiles in the upper atmosphere. With evidence of climate change impacts on the middle and upper atmosphere, monitoring and understanding trends through observational data is critical. There has been a contraction of the stratosphere and a decrease in the density of the upper atmosphere, which could impact the accumulation of space debris. This session invites presentations on scientific work related to various experimental/observational techniques, numerical and empirical modeling, and theoretical analyses on the dynamics, chemistry, and coupling processes in the altitude range of ~ 20 km to 180 km of the middle atmosphere and MLT regions, including long-term climatic changes. We look forward to your contribution to our EGU26 session. Please note that the abstract submission deadline is *Thursday, 15 January 2026, at 13:00 CET*. Thank you.
