Recent advances in liquid water flow modelling in the physics based SNOWPACK model

Michael Lehning, Nander Wever, Sebastian Würzer, Charles Fierz

Simulating liquid water flow in snow has deserved much attention in the physics based snow modelling community, as it is a crucial factor in understanding hydrological processes in alpine catchments, snowpack stratification and wet snow avalanche formation ...

Effect of salt on the H-bond symmetrization in ice

Philippe Gillet, Richard Gaal, Livia Eleonora Bove Kado

The richness of the phase diagram of water reduces drastically at very high pressures where only two molecular phases, proton-disordered ice VII and proton-ordered ice VIII, are known. Both phases transform to the centered hydrogen bond atomic phase ice X ...

Hydrometeor classification from polarimetric radar measurements: a clustering approach

Alexis Berne, Devis Tuia, Jacopo Grazioli

A data-driven approach to the classification of hydrometeors from measurements collected with polarimetric weather radars is proposed. In a first step, the optimal number of hydrometeor classes (nopt) that can be reliably identified from a large set of pol ...

Incorporating an advanced aerosol activation parameterization into WRF-CAM5: Model evaluation and parameterization intercomparison

Yi Zhang, Athanasios Nenes, Xiuwei Zhang

Aerosol activation into cloud droplets is an important process that governs aerosol indirect effects. The advanced treatment of aerosol activation by Fountoukis and Nenes (2005) and its recent updates, collectively called the FN series, have been incorpora ...

Silicon isotopes in angrites and volatile loss in planetesimals

James Badro

Inner solar system bodies, including the Earth, Moon, and asteroids, are depleted in volatile elements relative to chondrites. Hypotheses for this volatile element depletion include condensation from the solar nebula and volatile loss during energetic impa ...

Development of two-moment cloud microphysics for liquid and ice within the NASA Goddard Earth Observing System Model (GEOS-5)

Athanasios Nenes

This work presents the development of a two-moment cloud microphysics scheme within version 5 of the NASA Goddard Earth Observing System (GEOS-5). The scheme includes the implementation of a comprehensive stratiform microphysics module, a new cloud coverag ...

Steady-state macroscale voltammetry in a supercritical carbon dioxide medium

Hubert Girault, Astrid Johana Olaya Avendano, Dmitry Momotenko, Kathryn Ellen Toghill, Patrick Voyame

The electrochemical oxidation and reduction of decamethylferrocene is demonstrated in supercritical carbon dioxide at a macro gold disc electrode at 100 bar and 313 K. Fast mass transport effects were exhibited and the corresponding steady-state voltammetr ...

Sensitivity studies of dust ice nuclei effect on cirrus clouds with the community atmosphere model CAM5

Athanasios Nenes

In this study the effect of dust aerosol on upper tropospheric cirrus clouds through heterogeneous ice nucleation is investigated in the Community Atmospheric Model version 5 (CAM5) with two ice nucleation parameterizations. Both parameterizations consider ...

Saharan dust event impacts on cloud formation and radiation over Western Europe

Athanasios Nenes, Horst Vogel

We investigated the impact of mineral dust particles on clouds, radiation and atmospheric state during a strong Saharan dust event over Europe in May 2008, applying a comprehensive online-coupled regional model framework that explicitly treats particle mic ...

Volatilization induced by impacts recorded in Zn isotope composition of ureilites

Philippe Gillet, Pierre Beck

Ureilites are ultramafic achondrites formed by igneous processes early in the history of the Solar System. Ureilites are heavily depleted in volatile elements, probably by evaporation at the surface of the ureilite parent body: however the moderately volat ...
