Modular 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 ...
2024The Influence of the Planetary Boundary Layer on the Atmospheric State at an Orographic Site at the Eastern Mediterranean
Athanasios Nenes, Romanos Foskinis, Kunfeng Gao
We studied the influence of the Planetary Boundary Layer (PBL) on the air masses sampled at the mountaintop Hellenic Atmospheric Aerosol and Climate Change station ((HAC) 2 ) at Mount Helmos (Greece) during the Cloud-AerosoL InteractionS in the Helmos back ...
Stockholm Univ Press2024Turbulence 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 ...
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 ...
2024Turbulence in the Strongly Heterogeneous Near-Surface Boundary Layer over Patchy Snow
Michael Lehning, Dylan Stewart Reynolds, Michael Haugeneder
The near-surface boundary layer above patchy snow cover in mountainous terrain is characterized by a highly complex interplay of various flows on multiple scales. In this study, we present data from a comprehensive field campaign that cover a period of 21 ...
2024New Particle Formation Events Can Reduce Cloud Droplets in Boundary Layer Clouds at the Continental Scale
Athanasios Nenes, Spyros Pandis
New particle formation (NPF) substantially contributes to global cloud condensation nuclei (CCN), and their climate impacts. Individual NPF events are also thought to increase local CCN, cloud droplet number (CDN), and cloud albedo. High resolution simulat ...
Washington2024Correction to: Evidence of Strong Flux Underestimation by Bulk Parametrizations During Drifting and Blowing Snow
Varun Sharma, Michael Lehning, Wolf Hendrik Huwald, Jérôme François Sylvain Dujardin, Daniela Brito Melo, Francesco Comola, Armin Sigmund, Koichi Nishimura
Correction to: Boundary-Layer Meteorology (2022) 182:119–146 https://doi.org/10.1007/s10546-021-00653-x In the original article author found some corrections post publication that the units in Eq. 7 are currently not consistent and the text refers to a d ...
2023Low ozone dry deposition rates to sea ice during the MOSAiC field campaign: Implications for the Arctic boundary layer ozone budget
Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot
Dry deposition to the surface is one of the main removal pathways of tropospheric ozone (O3). We quantified for the first time the impact of O3 deposition to the Arctic sea ice on the planetary boundary layer (PBL) O3 concentration and budget using year-ro ...
2023Coupling of submeso-scale motion with near-surface turbulence over patchy snow cover
In spring, when the mountainous snow cover becomes patchy, the strong multi-scale surface heterogeneity influences atmospheric heat exchange processes. At valley scale, thermally driven winds advect warm air towards snow-covered regions at higher elevation ...
