Properties of Arctic liquid and mixed-phase clouds from shipborne Cloudnet observations during ACSE 2014
This study presents Cloudnet retrievals of Arctic clouds from measurements conducted during a 3-month research expedition along the Siberian shelf during summer and autumn 2014. During autumn, we find a strong reduction in the occurrence of liquid clouds a ...
COPERNICUS GESELLSCHAFT MBH2020Classical nucleation theory predicts the shape of the nucleus in homogeneous solidification
Michele Ceriotti, Bingqing Cheng, Gareth Aneurin Tribello
Macroscopic models of nucleation provide powerful tools for understanding activated phase transition processes. These models do not provide atomistic insights and can thus sometimes lack material-specific descriptions. Here, we provide a comprehensive fram ...
AMER INST PHYSICS2020Predicting homogeneous nucleation rate from atomistic simulations
Predictive modelling and quantitative understanding of nucleation is essential for predicting phase transformation processes in nature and precisely controlling material synthesis and processing. Atomistic modeling is a powerful tool for capturing the dyna ...
EPFL2019Theoretical prediction of the homogeneous ice nucleation rate: disentangling thermodynamics and kinetics
Michele Ceriotti, Bingqing Cheng
Estimating the homogeneous ice nucleation rate from undercooled liquid water is crucial for understanding many important physical phenomena and technological applications, and challenging for both experiments and theory. From a theoretical point of view, d ...
2018Implementation of a comprehensive ice crystal formation parameterization for cirrus and mixed-phase clouds in the EMAC model (based on MESSy 2.53)
A comprehensive ice nucleation parameterization has been implemented in the global chemistry-climate model EMAC to improve the representation of ice crystal number concentrations (ICNCs). The parameterization of Barahona and Nenes (2009, hereafter BN09) al ...

2018Initiation of secondary ice production in clouds
Disparities between the measured concentrations of ice-nucleating particles (INPs) and in-cloud ice crystal number concentrations (ICNCs) have led to the hypothesis that mechanisms other than primary nucleation form ice in the atmosphere. Here, we model th ...
Copernicus GmbH2018Water at Interfaces
Gabriele Tocci, Martin Hangaard Hansen, Eric Tyrode
The interfaces of neat water and aqueous solutions play a prominent role in many technological processes and in the environment. Examples of aqueous interfaces are ultrathin water films that cover most hydrophilic surfaces under ambient relative humidities ...
American Chemical Society2016Surface fractal dimension, water adsorption efficiency, and cloud nucleation activity of insoluble aerosol
Surface porosity affects the ability of a substance to adsorb gases. The surface fractal dimension D is a measure that indicates the amount that a surface fills a space, and can thereby be used to characterize the surface porosity. Here we propose a new me ...
Nature Publishing Group2016Simulating ice layer formation under the presence of preferential flow in layered snowpacks
Michael Lehning, Nander Wever, Sebastian Würzer, Charles Fierz
For physics-based snow cover models, simulating the formation of dense ice layers inside the snowpack has been a long-time challenge. Their formation is considered to be tightly coupled to the presence of preferential flow, which is assumed to happen throu ...
