“…These were similar in both magnitude and structure to that determined from Swarm. Ground based magnetometer data have also been combined with Swarm results to study wave disturbances of the Pi2 type geomagnetic field (Martines-Bedenko et al 2020). Such waves are traditionally associated with the onset of a substorm.…”

Swarm is the first European Space Agency (ESA) constellation mission for Earth Observation. Three identical Swarm satellites were launched into near-polar orbits on 22 November 2013. Each satellite hosts a range of instruments, including a Langmuir probe, GPS receivers, and magnetometers, from which the ionospheric plasma can be sampled and current systems inferred. In March 2018, the CASSIOPE/e-POP mission was formally integrated into the Swarm mission through ESA’s Earthnet Third Party Mission Programme. Collectively the instruments on the Swarm satellites enable detailed studies of ionospheric plasma, together with the variability of this plasma in space and in time. This allows the driving processes to be determined and understood. The purpose of this paper is to review ionospheric results from the first seven years of the Swarm mission and to discuss scientific challenges for future work in this field.

The dynamics of head-on collision of two magnetosonic solitary waves in ionosphere plasma of the Earth is investigated. A geomagnetic field model standing for the relation between a magnetic field and latitude is used to study nonlinear magnetosonic waves in the ionosphere of Earth. The linear and weakly nonlinear properties of magnetosonic waves are studied by the dispersion relation and the extended Poincaré–Lighthill–Kuo (PLK) method, respectively. Two coupled damped Korteweg–de Vries equations (dKdV) are derived for oppositely propagating magnetosonic solitary waves. The explicit solitary wave solutions are obtained in the weak collision limit, and the trajectories and phase shifts of two magnetosonic solitary waves are derived, which show that collisional dynamics and their phase shifts are dependent on the collision caused by neutral particles and the properties of the ionosphere. This study is applied to investigate the two-counterpropagating magnetosonic solitary waves located in the F2-region of the Earth's ionosphere at low latitude. This study should be beneficial to understand the interaction dynamics of the head-on nonlinear magnetosonic waves located in the F2 layer of the ionosphere when collision effects caused by neutral particles and geomagnetic field distribution are considered.
