Astrophysical measurements in the terrestrial environment

Plenary talk

9. Tomographic Research of Underground and large STructures with Muographic Expertise (TRUST-ME).

Clement Antoine Risso (LSBB - Laboratoire Souterrain a Bas Bruit (FR)), Dr Ignacio Lazaro Roche (LSBB - Laboratoire Souterrain a Bas Bruit (FR))

Couplings: Earth, solid, atmosphere, universe

Plenary talk

Transmission muography is a rising technique in domains such as geophysics and civil engineering. It provides dynamic information about the density distribution around the detector thanks to the attenuation of a natural, passive source: cosmic muons. This long-reach technology provides complementary information to classical prospecting tools for the study of active, heterogenous...

Couplings: Earth, solid, atmosphere, universe

Plenary talk

Geophysical measurements using highly sensitive Superconductive Quantum Interference Device (SQUID) sensors have been in use since more than two decades. Owing to their extreme sensitivity, SQUIDs require very low noise environment for stable operation. The requirement of unshielded environment for geophysical data acquisition further pushes the need to find ways to reduce unwanted cultural...

6. Monitoring the water stock using two vertically distributed superconducting gravimeters help to quantify evapotranspiration at daily time scale.

Plenary talk

Evapotranspiration (ET) is a major term of the water cycle which remains one of the biggest sources of uncertainty in hydrology. It is necessary to better understand this component and to develop new approaches to improve its quantification. Gravimetry is a geophysical method that measures variations in the Earth's gravity field “g”. Superconducting gravimeters (SG) provide continuous and...

11. Lightning initiation seen by the magnetic loop antennas installed at LSBB

Dr Ivana Kolmasova (Institute of Atmospheric Physics, Czech Academy of Sciences and Faculty of Mathematics and Physics, Charles University)

Couplings: Earth, solid, atmosphere, universe

Plenary talk

Sequences of bipolar pulses, which are believed to identify the initiation of the majority of both cloud-to-ground (CG) and intracloud lightning flashes in electromagnetic recordings, have been regularly detected by magnetic loop antennas installed at the external site of LSBB at Vestale on the Plateau d’Albion. Since 2013, numerous studies on lightning initiation based on the LSBB data...

15. Near subsurface density reconstruction by full waveform inversion in the frequency domain

Critical Zone

Plenary talk

The work proposed in this presentation is part of a global project dealing
with the characterisation of heterogeneous media by both electromagnetic and
mechanical full waveform inversion. Indeed Full Waveform Inversion (FWI) of
seismic reflection (SR) or Ground Penetrating Radar (GPR) data is an efficient
approach to reconstruct subsurface physical parameters with high resolution.
We...
