New Particle Formation Events Can Reduce Cloud Droplets in Boundary Layer Clouds at the Continental Scale
Athanasios Nenes, Spyros Pandis
New particle formation (NPF) substantially contributes to global cloud condensation nuclei (CCN), and their climate impacts. Individual NPF events are also thought to increase local CCN, cloud droplet number (CDN), and cloud albedo. High resolution simulat ...
Washington2024Nitrogen oxides in the free troposphere: implications for tropospheric oxidants and the interpretation of satellite NO2 measurements
Ilann Ernest Valentin Bourgeois
Satellite-based retrievals of tropospheric NO(2)columns are widely used to infer NOx (equivalent to NO + NO2) emissions. These retrievals rely on model information for the vertical distribution of NO2. The free tropospheric background above 2 km is particu ...
COPERNICUS GESELLSCHAFT MBH2023Supercell Thunderstorms in the Alpine Region - From Weather Radar Observations to Idealized Modeling
The high-impact nature and increasing occurrence of severe weather phenomena pushes forward research on their occurrence and improving our understanding thereof. Supercell thunderstorms are the focus of much severe convective research, as they represent on ...
EPFL2023Arrest Mechanisms of Buoyant Hydraulic Fractures
Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo, Dmitriy Garagash
Hydraulic fracturing (HF) treatments can form widespread fractures. Understanding their containment at depth is critical, given the positive buoyancy contrast between the fracturing fluid and the surrounding rock, promoting upward growth. We study arrest m ...

Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo, Dmitriy Garagash
Most anthropogenic applications of hydraulic fracturing treatments are performed in sedimentary basins. In these geological formations, the minimum compressive stress is usually horizontal and increases with depth. As a result, hydraulic fractures grow alo ...
2023Unconfined Plunging of a Hyperpycnal River Plume Over a Sloping Bed and Its Lateral Spreading: Laboratory Experiments and Numerical Modeling
David Andrew Barry, Ulrich Lemmin, Koen Blanckaert, Haoran Shi
Hyperpycnal (negatively buoyant) river inflow into lakes and oceans often develops three-dimensional (3D) plunging flow patterns when laterally unconfined. To determine the 3D flow pattern characteristics, laboratory experiments of laterally unconfined plu ...
2022Water vapor transport in snowpacks
This thesis is an in-depth treatment of water vapor transport in snowpacks and its impacts on snow structure. The aim is to better understand this transport process and to lay the basis for a model representation in physics-based multi-layer snow models. O ...
