Turbulence and Heat exchange in the Near-Surface Boundary Layer over Patchy Snow
The atmospheric layer adjacent to the earth's surface is of crucial importance for weather models due to the exchange of energy between the surface and the atmosphere. This exchange is dependent on the various surface properties and influences the state of ...
EPFL2024Modular Multiplatform Compatible Air Measurement System (MoMuCAMS): a new modular platform for boundary layer aerosol and trace gas vertical measurements in extreme environments
Julia Schmale, Andrea Baccarini, Roman Pohorsky
The Modular Multiplatform Compatible Air Measurement System (MoMuCAMS) is a newly developed in situ aerosol and trace gas measurement platform for lower-atmospheric vertical profiling. MoMuCAMS has been primarily designed to be attached to a Helikite, a ru ...

The Modular Multiplatform Compatible Air Measurement System (MoMuCAMS) is a newly developed in situ aerosol and trace gas measurement payload for lower atmospheric vertical profiling in extreme environments. MoMuCAMS is a multiplatform compatible system, p ...
2023Controlled crystallization and surface engineering of mixed-halide y-CsPbI2Br inorganic perovskites via guanidinium iodide additive in air-processed perovskite solar cells
In this report, we demonstrate enlarged grain size (up to-3 lm) in ambient-stable black c-phase CsPbI2Br thin films through the regulated addition of guanidinium iodide (GAI) as an effective volatile additive. Nuclear magnetic resonance (NMR) and X-ray pho ...
Oxford2023Whirling instability of an eccentric coated fibre
François Gallaire, Edouard Boujo, Shahab Eghbali, Ludovic Pierre Gustave Keiser
We study a gravity-driven viscous flow coating a vertical cylindrical fibre. The destabilisation of a draining liquid column into a downward moving train of beads has been linked to the conjunction of the Rayleigh-Plateau and Kapitza instabilities in the l ...
CAMBRIDGE UNIV PRESS2022An analytical approximation of urban heat and dry islands and their impact on convection triggering
It is well known that cities increase air and surface temperatures compared to their rural sur-roundings, the so-called urban heat island (UHI) effect. However, the associated changes in at-mospheric humidity (also known as urban dry island, UDI) and conve ...
ELSEVIER2022An evaluation of new particle formation events in Helsinki during a Baltic Sea cyanobacterial summer bloom
Several studies have investigated new particle formation (NPF) events from various sites ranging from pristine locations, including forest sites, to urban areas. However, there is still a dearth of studies investigating NPF processes and subsequent aerosol ...
COPERNICUS GESELLSCHAFT MBH2022Climatology of atmospheric boundary layer height over Switzerland
Benjamin Jérémy Laurent Heutte
Determining the height of the planetary boundary layer (PBL) is of crucial importance as it is a key parameter in air-quality modelling and weather forecasting. Continuous remote sensing measurements allow to estimate this parameter based on temperature, h ...
2021Informed scenario-based RRT∗ for aircraft trajectory planning under ensemble forecasting of thunderstorms
Maryam Kamgarpour, Eduardo Andres Enderiz
Thunderstorms represent a major hazard for flights, as they compromise the safety of both the airframe and the passengers. To address trajectory planning under thunderstorms, three variants of the scenario-based rapidly exploring random trees (SB-RRTs) are ...
2021Impact of warm air mass intrusions on atmospheric chemistry and microphysics: Observations during MOSAiC
Julia Schmale, Ivo Fabio Beck, Lubna Dada
Arctic winter is dominated by anthropogenic haze, while pollution transport from mid-latitudes decreases in summertime. As a result, aerosol concentrations reach a maximum in winter and drop to minimum in summer. What happens during the season transition, ...
