CEDAR email: EGU26: Exploringr Near-Earth Magnetic Field and the Ionosphere-Thermosphere Environment

[Astrid Maute]

Dear CEDAR community, 

We would to invite you to present your work at the EGU session “LEO
satellites for Exploring the near-Earth Magnetic Field and the
Ionosphere-Thermosphere Environment”
(https://meetingorganizer.copernicus.org/EGU26/session/55987)

We solicit contributions in geomagnetism, ionospheric, and thermospheric
sciences related to the Earth and near-Earth processes, with a focus on
existing and planned LEO satellites. Studies consisting in combined analysis
of multi-mission satellite data, including missions such as ICON and EZIE,
with ground-based data or models are welcome. We also welcome studies that
use innovative approaches, such as data assimilation-based techniques. 

EGU General Assembly (https://www.egu26.eu/) takes 3–8 May, in Vienna and
online. The abstract submission deadline is Thursday, 15 January 2026, 13:00
CET. 

Best regards,

Martin Fillion, Alexander Grayver, Astrid Maute, Alessio Pignalberi,
Enkeledja Qamili

Full session description:

Low-Earth orbit (LEO) satellites provide unique opportunities to
characterize the Earth's magnetic field, ionospheric currents and plasma
parameters, and thermospheric density and winds across a wide spectrum of
time and spatial scales, and for a large range of solar and geomagnetic
activities. At the forefront of this advance are the three ESA Earth
Explorer Swarm satellites, which have been providing high-accuracy
measurements of the Earth's magnetic field, electric field, plasma
parameters, precise-orbit determination, and accelerometer observations
since their launch in November 2013. They have proven very valuable for
studying the near-Earth magnetic field and the coupled
ionospheric-thermospheric environment, and enabled the development and
implementation of advanced models and operational space weather services.
The scientific potential of the polar-orbiting Swarm satellites is today
augmented by newly available data, especially those collected by the
low-inclination Macau Science Satellite 1 and CSES satellites.
In addition, the ESA Scout NanoMagSat constellation, consisting of one
near-polar and two 60° inclination satellites, is scheduled to launch near
the end of 2027, with full operation planned for 2028. It will acquire
high-accuracy magnetic vector and scalar data, electron density, and
electron temperature data, navigation data, and collect ionospheric
radio-occultation profiles. All these data are also complemented by
increasingly available platform-magnetometer data, such as from the
CryoSat-2, GRACE, GRACE-FO, GOCE, and E-POP satellites. The new abundance of
satellite data provides unprecedented space-time data coverage at LEO
satellite altitudes, opening the way for new scientific opportunities.

We invite contributions in geomagnetism, ionospheric, and thermospheric
sciences related to the Earth and near-Earth processes, with a focus on
existing and planned LEO satellites. Studies consisting in combined analysis
of multi-mission satellite data, including missions such as ICON and EZIE,
with ground-based data or models are welcome. We also welcome studies that
use innovative approaches, such as data assimilation-based techniques.
