Implementation of the sectional aerosol module SALSA2.0 into the PALM model system 6.0: Model development and first evaluation

Kurppa, M.; Hellsten, A.; Roldin, P.; Kokkola, H.; Tonttila, J.; Auvinen, M.; Kent, C.; Kumar, P.; Maronga, Björn; Järvi, L. (Göttingen : Copernicus GmbH, 2019)

Urban pedestrian-level air quality is a result of an interplay between turbulent dispersion conditions, background concentrations, and heterogeneous local emissions of air pollutants and their transformation processes. ...
An Investigation of the Grid Sensitivity in Large-Eddy Simulations of the Stable Boundary Layer

Maronga, Björn; Li, Dan (Dordrecht [u.a.] : Springer Science + Business Media B.V, 2021)

We revisit the longstanding problem of grid sensitivity, i.e., the lack of grid convergence in large-eddy simulations (LES) of the stable boundary layer. We use a comprehensive set of LES of the well-known Global Energy ...
Large-eddy simulation of a 15 GW wind farm: Flow effects, energy budgets and comparison with wake models

Maas, Oliver (Lausanne : Frontiers Media, 2023)

Planned offshore wind farm clusters have a rated capacity of more than 10 GW. The layout optimization and yield estimation of wind farms is often performed with computationally inexpensive, analytical wake models. As recent ...
On the effect of nocturnal radiation fog on the development of the daytime convective boundary layer: A large-eddy simulation study

Schwenkel, Johannes; Maronga, Björn (Weinheim [u.a.] : Wiley, 2022)

The potential effect of failing to predict nocturnal deep radiation fog on the development of the daytime convective boundary layer (CBL) is studied using large-eddy simulations. Typical spring and autumn conditions for ...
PALM-USM v1.0: A new urban surface model integrated into the PALM large-eddy simulation model

Resler, Jaroslav; Krč, Pavel; Belda, Michal; Juruš, Pavel; Benešová, Nina; Lopata, Jan; Vlček, Ondrej; Damašková, Dasa; Eben, Krystof; Derbek, Premysl; Maronga, Björn; Kanani-Sühring, Farah (Göttingen : Copernicus GmbH, 2017)

Urban areas are an important part of the climate system and many aspects of urban climate have direct effects on human health and living conditions. This implies that reliable tools for local urban climate studies supporting ...
The Parallelized Large-Eddy Simulation Model (PALM) version 4.0 for atmospheric and oceanic flows: model formulation, recent developments, and future perspectives

Maronga, Björn; Gryschka, Micha; Heinze, Rieke; Hoffmann, Fabian; Kanani-Sühring, Farah; Keck, Marius; Ketelsen, K.; Letzel, M.O.; Sühring, Matthias; Raasch, Siegfried (Göttingen : Copernicus, 2015-02-19)

In this paper we present the current version of the Parallelized Large-Eddy Simulation Model (PALM) whose core has been developed at the Institute of Meteorology and Climatology at Leibniz Universität Hannover (Germany). ...
Toward Large-Eddy Simulations of Dust Devils of Observed Intensity: Effects of Grid Spacing, Background Wind, and Surface Heterogeneities

Giersch, S.; Brast, M.; Hoffmann, F.; Raasch, S. (Hoboken, NJ : Blackwell Publishing Ltd, 2019)

Dust devils are convective vortices with a vertical axis of rotation made visible by lifted soil particles. Currently, there is great uncertainty about the extent to which dust devils contribute to the atmospheric aerosol ...
