Low-Altitude Boundary-Layer Flows and Dispersion: Insights from Experiments, Modeling and AI

Dear Colleagues,

The low-altitude boundary layer constitutes the lowest portion of the atmospheric boundary layer, where flow dynamics and dispersion characteristics are significantly influenced by surface roughness. Characterizing or predicting flows over heterogeneous surfaces, such as urban terrain, is particularly challenging due to non-uniform shear stress, flow recirculation, and heterogeneous heat and pollutant sources. Nevertheless, this region encompasses the environment where urban residents live, and understanding local wind flows and air pollutant dispersion is critical for improving urban safety and living conditions. Additionally, complex shear flows pose operational risks for low-altitude unmanned aerial vehicles (UAVs).

This Special Issue aims to advance contemporary methodologies and deepen our understanding of flow and dispersion phenomena in low-altitude boundary-layer environments. The expected outcomes will support a range of environmental and engineering applications, including strategies for mitigating UAV flight hazards and tackling pressing real-world challenges. We invite high-quality studies employing traditional approaches (field observations, wind tunnel experiments, numerical simulations, and theoretical analysis), as well as novel AI techniques. Contributions should enhance current knowledge, propose innovative modeling tools for flow and dispersion patterns in low-altitude boundary layers, and offer valuable insights to the broader scientific community.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Atmosphere is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
