Full waveform inversion of infrasound: Sensitivity kernels from the adjoint method along with non-linear inversion tests Open
Summary Atmospheric models are based on various types of geophysical data, including lidar and radar. Infrasounds, acoustic waves that can propagate over large distances, have not yet been used in atmospheric models, although they provide …

Forward modeling of quake’s infrasound recorded in the stratosphere on board balloon platforms Open
Acoustic waves generated by seismic waves contain information on the internal structure of planets, and can be sensed by pressure sensors onboard high-altitude balloons. To identify the various contributions (infrasound signal, noise, ball…

Geographical, Seasonal and Diurnal Variations of Acoustic Attenuation, and Sound Speed in the Near‐Surface Martian Atmosphere Open
This work introduces a comprehensive model of sound attenuation and speed on Mars, in light of the recent operation of several microphones on the surface of Mars. The proposed acoustic model calculates the sound speed and attenuation throu…

Development of a full waveform inversion method for acoustic waves in the presence of wind: application to synthetic and realistic cases  Open
Inferring a model of the wind, pressure, velocity in the atmosphere is an inverse problem, for which the state of the art methods use the travel times of acoustic waves.We aim to solve such an inverse problem by adding more information and…

Stratospheric Balloon Observations of Infrasound Waves From the 15 January 2022 Hunga Eruption, Tonga Open
The 15 January 2022 eruption of the Hunga volcano (Tonga) generated a rich spectrum of waves, some of which achieved global propagation. Among numerous platforms monitoring the event, two stratospheric balloons flying over the tropical Pac…

Infrasound From Large Earthquakes Recorded on a Network of Balloons in the Stratosphere Open
The ground movements induced by seismic waves create acoustic waves propagating upward in the atmosphere, thus providing a practical solution to perform remote sensing of planetary interiors. However, a terrestrial demonstration of a seism…

Stratospheric observations of acoustic-gravity waves from the Hunga-Tonga eruption Open
<p>In the frame of the Strateole 2 balloon project, 17 long-duration stratospheric balloons were launched from Seychelles in fall 2021. At the time of the main eruption of Hunga-Tonga on January 15 2022, two balloons were still in fl…
