Development of Hyphenated Analytical Techniques using spICP-MS for Online Characterization of Metallic Nanoparticles in Aerosols
The presence of metallic nanoparticles (NPs) in aerosols has raised concern about their fate in the environment through natural processes and anthropological activities. The state-of-the-art technologies for direct aerosol characterization cannot reach rea ...
EPFL2024Understanding snow saltation parameterizations: lessons from theory, experiments and numerical simulations
Michael Lehning, Daniela Brito Melo, Armin Sigmund
Drifting and blowing snow are important features in polar and high mountain regions. They control the surface mass balance in windy conditions and influence sublimation of snow and ice surfaces. Despite their importance, model representations in weather an ...
2024Role of K-feldspar and quartz in global ice nucleation by mineral dust in mixed-phase clouds
Ice-nucleating particles (INPs) enable ice formation, profoundly affecting the microphysical and radiative properties, lifetimes, and precipitation rates of clouds. Mineral dust emitted from arid regions, particularly potassium-containing feldspar (K-felds ...
COPERNICUS GESELLSCHAFT MBH2023Ecological and Climate Impacts of Greenlandic Glacial Outwash Plains (ECO-Plains)
Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh
Glacial outwash plains are developing fast in the Arctic, a region which warms two to four times faster than the global average. These new landscapes are climate relevant. They can be sources and sinks of greenhouse gas fluxes and they expose large amounts ...
2023Rotating disk diluter hyphenated with single particle ICP-MS as an online dilution and sampling platform for metallic nanoparticles characterization in ambient aerosol
Christian Ludwig, Andrea Testino, Tianyu Cen
The application of single particle inductively coupled plasma mass spectrometry (spICP-MS) for online metallic nanoparticles (NPs) characterization in ambient aerosol remains a challenge. In this study, a hyphenated setup consisting of a rotating disk dilu ...
2023Water soluble reactive phosphate (SRP) in atmospheric particles over East Mediterranean: The importance of dust and biomass burning events
Athanasios Nenes, Kalliopi Violaki, Christos Panagiotopoulos
The importance of dust and biomass burning episodes on the atmospheric concentration of water-soluble reactive phosphate (SRP) was determined in the eastern Mediterranean. SRP was measured with a new rapid real-time automated analytical system with a time ...
ELSEVIER2022Modeling Snow Saltation: The Effect of Grain Size and Interparticle Cohesion
Varun Sharma, Michael Lehning, Daniela Brito Melo, Francesco Comola, Armin Sigmund
The surface of the Earth is snow-covered at least seasonally over large areas. This snow surface is highly dynamic, particularly under the influence of strong winds. The motion of snow particles driven by the wind not only changes the snow cover but has im ...
