Urban Thermal Environment Evolution, Theoretical Analysis and Strategies for Mitigations and Adaption

Dear Colleagues,

Across the world, the urban heat environment is getting increasingly intense under the joint effects of global climate change and anthropogenic activities. In the latest IPCC AR6 report, cities have been highlighted as the hotspots of climate impacts. The exacerbated urban thermal environment would exert a strong influence on thermal comfort, human health, building energy use, CO2 emissions, vegetation phenology and so forth. Although the urban heat environment has received great attention in the urban climate community, fine-scale spatiotemporal research is still lacking. Undoubtedly, advances in new technologies (e.g., refined mesoscale models, artificial intelligence and multi-source satellite remote sensing platforms) will help to increase understanding of urban thermal environment towards fine scales.

This Special Issue aims to combine multi-technology (satellite remote sensing, artificial intelligence and numerical models) to investigate: (1) the evolution of SUHI (Surface Urban Heat Island), CUHI (Canopy Urban Heat Island), LST (Land Surface Temperature), Ta (Air temperature) due to urbanization; (2) theoretical analysis of urban thermal environment; and (3) heat mitigation and adaption measures.

The main topics of this Special Issue include but are not limited to:

• Impact of urban extension and vertical growth on SUHI/CUHI/LST/Ta;
• High-resolution spatiotemporal analysis of SUHI/LST;
• High-resolution spatiotemporal analysis of CUHI/Ta;
• Impact of 3D urban morphology (e.g., building and trees) on LST and Ta;
• Anthropogenic activities impact on SUHI, CUHI, LST and Ta;
• Heat mitigation measures, e.g., blue-green space, urban ventilation, building and street properties (e.g., shape, materials, reflective surfaces), and so forth;
• Outdoor thermal comfort simulation (UTCI, PET etc.).

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.
