Special Issue Information

Dear Colleagues,

Urban climate projections are vital to precisely quantify the future threats to life, from the occurrence of climate disasters (e.g., heatwaves, hurricanes) to the degradation of basic necessities. Of the factors directly considered in climate projections, human-induced surface forcing (e.g., greenhouse gas emissions, land cover modifications) is possibly the most dominant to date. Meanwhile, the urban surface that supplies these forcings is dynamically changing at rates which are spatially heterogeneous and most likely influenced by climatic changes. Eventually, two questions arise: (1) Are there state-of-the-art climate projections that consider these interactions? (2) To what extent is it possible to estimate the contribution of urban/land cover modifications in climate projections?

In this Special Issue, we explore scientific advancements of methodologies and tools that can provide logical climate forecasts or projections that adequately consider pathways of urban/land cover changes (or even unprecedented global changes, such as the current COVID-19 pandemic). The expected time scales are from short-term (e.g., weeks, months) to long-term (i.e., decades, centuries), with spatial scales covering anything from cities to the whole planet. The topics of interest include but are not limited to the following:

  • Urban climate change/projection models released or updated within the recent decade;
  • Climate projections, or methodologies of such, which consider realistic changes of the urban/land surface;
  • Climate projections, or methodologies of such, which consider unprecedented global disasters (e.g., COVID-19);
  • Proposals/strategies to forecast changes in the urban/land surface that are climate-induced or vice versa;
  • Multiscale downscaling of urban climate projections;
  • Recent developments, implementations, or methodologies in global climate models to estimate future urban climate projections.

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).

Anthropogenic greenhouse gas emissions are increasing the frequency of deadly heat waves. Heat waves are particularly devastating in cities, where air pollution is high and air temperatures are already inflated by the heat island effect. Determining how cities can ameliorate extreme summer temperature is thus critical to climate adaptation. Tree planting has been proposed to ameliorate urban temperatures, but its effectiveness, particularly of coniferous trees in temperate climates, has not been established. Here, we use remote sensing data (Landsat 8), high-resolution land cover data, and Bayesian models to understand how different tree and land cover classes affect summer surface temperature in Metro Vancouver, Canada. Although areas dominated by coniferous trees exhibited the lowest albedo (95% CrI 0.08–0.08), they were significantly (12.2 °C) cooler than areas dominated by buildings. Indeed, we found that for conifers, lower albedo was associated with lower surface temperatures. Planting and maintaining coniferous trees in cities may not only sequester CO2 to mitigate global climate change, but may also ameliorate higher temperatures and deadly heat waves locally.
