Special Issue Information

Dear Colleagues,

We invite researchers to contribute original research articles and review articles dealing with all aspects of monitoring and modelling air pollution and the thermal environment through applications in urban areas.

Research efforts in modelling the dispersion of atmospheric pollutants and the microclimate have, until recently, mainly been focused on improving the understanding and modelling of physical and dynamical processes affecting the ventilation and pollutant transport in the urban environment. More and more field measurements have also been carried out to monitor air pollution and the thermal environment. Some emphasize urban air pollution and exposure assessment, while others focus on the outdoor thermal environment and thermal comfort. Only a few outdoor experiments and modelling works investigated both of them.

Contributions to this Special Issue may include advanced and original experimental and modelling studies, techniques, numerical simulations and developments aimed at evaluating urban ventilation, pollutant dispersion, and thermal environment/comfort in cities. We are also interested in reviews proposing future perspectives. This Special Issue is a follow-up to the first Special Issue entitled “Monitoring and Modelling Air Pollution and Thermal Environment through Applications in Urban Areas” (https://www.mdpi.com/journal/atmosphere/special_issues/monitoring_modelling_air_pollution_applications) published in Atmosphere in 2022.

Topics of interest include, but are not limited to:

  • Data (meteorological and air quality) from new field campaigns and wind tunnel experiments in cities;
  • Numerical simulations at various scales on urban ventilation/air pollution/thermal environment;
  • Experimental and modeling application studies of idealized and real cities with attention to compact cities and high-rise buildings;
  • Effects of urban morphology on air pollution and/or outdoor thermal environment/thermal comfort;
  • Mitigation (and adaptation) strategies of urban air pollution and thermal discomfort.

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 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.

Urban green and blue infrastructure (GBI) is effective in urban heat mitigation. However, the diurnal variations in the thermal regulation of GBI on different types of urban pedestrian walkways in the subtropical humid climate zone are unclear. Based on traverse measurements in January 2022, this study investigates how outdoor air temperature (Ta) and wet-bulb temperature (Tw) at the pedestrian level are affected by various urban morphology and GBI characteristics in the central urbanized area of Guangzhou (China). Six building-related, three vegetation-related, and three water-related parameters were applied in the analyses. Results show that green infrastructure (GI) has the strongest cooling effect (Pearson’s coefficient r = −0.33~−0.54) on Ta on cloudy evenings and the weakest cooling effect (r = −0.22~−0.32) on clear evenings. Blue infrastructure (BI) exhibits the highest correlations with the cooling effect for Ta on clear afternoons (r = −0.35~−0.51) and weaker, but more consistent, correlations throughout cloudy days (r = −0.23~−0.43). Strong correlations between GI and Tw cooling are observed in the morning and evening on clear days (r = −0.13~−0.48), while BI exhibits the strongest correlation with Tw cooling on clear afternoons (r = −0.13~−0.37). In addition, both GI and BI show a greater cooling effect on both Ta and Tw in low-rise areas compared to high-rise areas. Compared to the individual GI or BI, the integrated GBI has a higher cooling intensity for both Ta and Tw in high-rise areas. However, the cooling potential of integrated GBI is slightly lower for both Ta and Tw during noon and afternoon in low-rise areas. The findings of this study give insights into urban GBI planning and design of specific urban microclimate regulation strategies. Full article
