PhD opportunity: Coupling between atmosphere and Earth’s crust

At KIT we have a job opening for PhD students funded within the DFG Research Unit RING (Rotations in Physics, Geophysics and Geodesy). We are looking for ambitious candidates: Curious to understand how the atmosphere above your head kneads the Earth’s crust beneath your feed? A summary of what we plan to do: We will investigate local deformation of the Earth’s crust induced by atmospheric loading. This is a major mechanism for rotational and horizontal component background noise in the normal mode band, for which we plan to develop mitigation procedures. We will deploy a large-N array of autonomous barometers in the vicinity of Black Forest Observatory (BFO). This shall provide unique insights into the dynamics of the local atmosphere with a temporal and spatial resolution not previously available. From the data obtained in this way parametric descriptions of time‑varying lateral gradients of air‑pressure shall be derived. These gradients contribute to crustal deformation. The resulting local rotation of sensors in the observatory is sensed as a disturbance due to tilt‑coupled gravity and shall be explained in a quantitative, deterministic way by the barometric time series. In the long term, this is intended to improve the quality of normal mode observations by means of a signal correction.
