Special Issue Information

Dear Colleagues,

Three-dimensional simulations of dispersion at the local scale as well as at the meso-scale are required for topics as varied as forecasting air quality or evaluating the consequences of accidents involving significant releases into the atmosphere. These calculations are based on meteorological forecasts, also multi-scale, from synoptic weather to flows generated by the very local effects of relief, land use, or buildings of an industrial site or a city. Applications involving physical models adapted to different scales are not new, but they are increasingly common due to the interest they inspire and the increasingly powerful computational resources available. However, beyond the coupling of models (the outputs of some are the inputs of others), multi-scale simulations pose difficulties that are far from being resolved. Thus, for example, from the point of view of flows, there is a question of how to rigorously evaluate the instantaneous local turbulence which results doubly from a distant atmospheric component and from a component of proximity effects. Regarding the sources associated with the different scales, there is a question of how not to take them into account several times. Finally, from the point of view of atmospheric dispersion, there is a question of how to manage simulations in nested domains of different resolutions or transport numerical particles through these domains over very long distances.

In this Special Issue, we propose to bring together research and application articles on multi-scale modeling and simulation. In particular, the articles will focus on:

  • Any theoretical consideration allowing a better understanding of the multi-scale physics of flows and dispersion in the atmosphere;
  • Any practical consideration allowing us to carry out rigorous and, if possible, efficient simulations of the dispersion from the smallest scale to the largest scale (or vice versa);
  • The presentation of multi-scale modeling systems for the dispersion of chronic or accidental releases;
  • Taking into account uncertainties and data assimilation when weather forecasts and/or dispersion simulations are carried out at different scales;
  • The estimation of source terms when it involves retro-dispersion simulations at multiple scales.

This list is not exhaustive, and this Special Issue of the journal Atmosphere will aim to share the knowledge and experience of researchers and engineers who must work both at the local scale and at the meso-scale to address atmospheric dispersion.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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-blind 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 2000 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.
