Heisel, Michael; Chen, Bicheng; Kok, Jasper; Chamecki, Marcelo (2021), Data from: Gentle topography increases vertical transport of coarse dust by orders of magnitude, Dryad, Dataset, https://doi.org/10.5068/D15Q4C
The dataset is a collection of computational results based on large-eddy simulation (LES) of the atmospheric boundary layer and Lagrangian tracking of coarse dust particles. Three simulations of the boundary layer are included: over flat terrain, over a small 50 m hill, and over a large 100 m hill. The LES was wall-modeled, and the two-dimensional hill was represented using immersed boundary methods.
Coarse dust particles were released near the ground in the simulations and their trajectories were tracked based on the LES velocity fields. Three particle sizes - 5, 20, and 60 micrometer diameter - were released for each of the three LES topography cases, thus totaling nine scenarios. Further details regarding the methodology are available in the related article.
The data comprise processed statistics corresponding to the published results of the simulations. These include time-averages LES velocities and particle trajectory statistics. The data are organized as tab-separated values in text files, where the header rows provide relevant information. The figure number in each file name refers to the corresponding figure in the related article.
