In the JOIN project, the team will develop new tools for estimating the amount of Joule Heating in the Northern auroral regions, and carry out a detailed investigation of its consequences on the neutral atmosphere at satellite altitudes. The high-latitude auroral ionosphere is connected by magnetic field lines to a large part of the magnetospheric …
The day-to day variability of quiet-time ionosphere is surprisingly high even during periods of negligible solar forcing. Relatively well understood is the high-latitude variability where the solar wind is directly driving the high latitude currents, convection electric field or polar aurorae. But the current understanding does not allow to accurately model the ionospheric state during …
Combining satellite measurements from Swarm, as well as from the earlier German Champ mission and Danish Ørsted mission, with a computer model of the geodynamo, a new type of magnetic wave, with a 7 year period, and a westward drift at phase speed of 1500km/year, has been mapped at the Earth’s core-mantle boundary. Such Magneto-Coriolis …
The 2021 SWARM+SCIENCE workshop, successfully held on 28–29 June, brought together ESA experts and the Swarm community to discuss the most relevant results of recent ESA projects in the context of magnetosphere – ionosphere – lower atmosphere interactions and to identify the main open questions to be addressed in coming years. The Agency is pleased to …
“I greatly value the opportunity that ESA gave me as a postdoc to be able to fully pursue and lead my own programme of research. The experience was an invaluable one, allowing me to grow my academic career.” After completing his fellowship today Daniel is Assistant Professor at the University of Saskatchewan Read …
Living Planet Fellowship research project carried out by Daniel Billet. The Earth’s upper polar atmospheric region is constantly bombarded with energy input from the interaction between the magnetosphere and the solar wind. This controls immediately visible phenomena like the aurora borealis and australis, but also results in changes to the composition and dynamics of the atmosphere itself. …
The goal of the 4D-Earth-Swarm project, supported by ESA, is to improve our understanding of the rapid (interannual) changes in the geomagnetic field, as recorded by the three satellites of the Swarm mission of ESA – as well as earlier satellite missions such as CHAMP and Oersted, and ground-based observatories. The project is planned for …
