Good enough: Intermediate complexity atmospheric models improve the representation of processes affecting seasonal snow
Snow plays a crucial role in processes regulating ecosystems, the climate, and human development. Mountain snowpack in particular has great relevance for downstream communities. Knowledge about the distribution and properties of the snowpack thus help in p ...
EPFL2024Physicochemical characterization and source apportionment of Arctic ice-nucleating particles observed in Ny-Alesund in autumn 2019
Athanasios Nenes, Ghislain Gilles Jean-Michel Motos, Jörg Wieder, Guangyu Li
Ice-nucleating particles (INPs) initiate primary ice formation in Arctic mixed-phase clouds (MPCs), altering cloud radiative properties and modulating precipitation. For atmospheric INPs, the complexity of their spatiotemporal variations, heterogeneous sou ...
Gottingen2023Modelling the coupled mercury-halogen-ozone cycle in the central Arctic during spring
Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot, Jenny Thomas
Near-surface mercury and ozone depletion events occur in the lowest part of the atmosphere during Arctic spring. Mercury depletion is the first step in a process that transforms long-lived elemental mercury to more reactive forms within the Arctic that are ...
2023A Snapshot on the Buildup of the Stable Water Isotopic Signal in the Upper Snowpack at EastGRIP on the Greenland Ice Sheet
The stable water isotopic composition in firn and ice cores provides valuable information on past climatic conditions. Because of uneven accumulation and post-depositional modifications on local spatial scales up to hundreds of meters, time series derived ...
AMER GEOPHYSICAL UNION2023Diurnal and seasonal patterns of global urban dry islands
Urban heat islands (UHIs) are a widely studied phenomenon, while research on urban-rural differences in humidity, the so called urban dry or moisture islands (UDIs, UMIs), is less common and a large-scale quantification of the seasonal and diurnal patterns ...
2022Future trends in wind resources and their consistency in the Indian sub-continent
Michael Lehning, Adrien Michel, Yasmine Zakari
We use the latest Coordinated Regional Dynamical Experiment regional climate models over South Asia at 0.22 degrees grid spacing (WAS-22) under two Representative Concentration Pathways scenarios (RCP 2.6 and RCP 8.5) to evaluate their performance against ...
ELSEVIER2022Analyzing the effects of snow-atmosphere interactions on snow surface dynamics based on automated 3D laser scanning data
The snow surface morphology is shaped throughout a winter season by atmospheric conditions, like precipitation, wind, solar irradiance, air temperature or relative humidity. Changes in morphology affect the snow surface roughness which influences the turbu ...
