Offer Description A world-renowned geosciences organisation, the IPGP is associated with the CNRS and an integrated institute of the Université Paris Cité. Bringing together more than 500 people, the IPGP studies the Earth and the planets from the core to the most superficial fluid envelopes, through observation, experimentation and modelling.
The research areas are structured through 4 main unifying themes: Interiors of the Earth and Planets, Natural Hazards, Earth System and Origins.
The IPGP is in charge of labelled observation services in volcanology, seismology, magnetism, gravimetry and erosion. It also operates permanent observatories to monitor the four active French overseas volcanoes in Guadeloupe, Martinique, Réunion Island and Mayotte.
The IPGP hosts powerful computing resources and state-of-the-art experimental and analytical facilities and benefits from first-class technical support. The IPGP provides its students with geosciences training that combines observation, quantitative analysis and modelling, and reflects the quality, richness and thematic diversity of the research conducted by the IPGP teams.
Team Department The Geomagnetism Team is one of the 17 research teams within IPGP. It works mainly on the study of the Earth's magnetic field, i.e. the natural phenomena that produce magnetic signals, as well as on the study of the Earth's global dynamics. The team plays a leading international role in proposing and operating space missions to monitor and study the Earth's magnetic field and ionospheric environment. The team develops advanced modelling and numerical simulation codes. In particular, it exploits data acquired in observatories and on board satellites, such as those on the ESA Swarm mission currently in operation, for which it is responsible for the absolute magnetometers.
Missions The ESA Earth Explorer Swarm mission comprises 3 satellites launched in 2013 on quasi-polar Low Earth Orbits (LEO) slowly drifting in local time, to investigate all the sources of the Earth's magnetic field. This mission has already been extended up to early 2026 and further extensions up to end of 2028 and beyond are already under consideration. Each Swarm satellite carries an Absolute Scalar Magnetometer (ASM) under the scientific responsibility of IPGP, built by CEA-Léti and provided by CNES as a Customer Furnished Instrument.
The main signals of interest for this project will be lightning-generated whistlers in the Extremely Low Frequencies (ELF) range already routinely observed in the Swarm Burst mode data. The investigation of these signals can therefore provide important information about the distribution of lightning in the neutral atmosphere, the conditions allowing the ELF signal to penetrate the ionosphere, and the state of the ionosphere along the path of the signal between the lightning and the satellites.
