Vegetation cover and plant-trait effects on outdoor thermal comfort in a tropical city

An increase in urban vegetation is an often proposed mitigation strategy to reduce urban heat and improve outdoor thermal comfort (OTC). Vegetation can alter urban microclimate through changes in air temperature, mean radiant temperature, humidity, and win ...

Quantifying the impacts of urban morphology on modifying microclimate conditions in extreme weather conditions

Jean-Louis Scartezzini, Kavan Javanroodi, Vahid Moussavi Nik

It is well-known that the morphology of urban areas modifies the variations of climate variables at microscale; known as microclimate conditions. The complexity of urban morphology can lead to undesired wind conditions or excessive air temperature; particu ...

Aqueous-phase reactive species formed by fine particulate matter from remote forests and polluted urban air

Andrea Mario Arangio, Ting Zhang, Jing Li

In the aqueous phase, fine particulate matter can form reactive species (RS) that influence the aging, properties, and health effects of atmospheric aerosols. In this study, we explore the RS yields of aerosol samples from a remote forest (Hyytiala, Finlan ...

Magic Walls

Andrew James Sonta

Reducing energy demand on buildings’ heating and cooling systems is fundamental to reaching a carbon-neutral future. Writing in iScience, Xu and Raman show that by controlling radiative heat flows in buildings with novel materials, we can expand the set of ...

Human circadian rhythms and urban density: celebrating the natural day-night cycle

Marilyne Andersen, Mark Pauly, Florin Isvoranu, Megan Nicole Danell, Javier Fernandez Contreras

Our exposure to light has a key role in regulating our biological clock through a dedicated photoreceptor present in the human eye. Increased awareness to its criticality when it comes to human well-being is urgently needed, as this criticality is potentia ...

Seasonal hysteresis of surface urban heat islands

Gabriele Manoli, Gabriel George Katul

Temporal dynamics of urban warming have been extensively studied at the diurnal scale, but the impact of background climate on the observed seasonality of surface urban heat islands (SUHIs) remains largely unexplored. On seasonal time scales, the intensity ...

Spatio-Temporal Relationship between Land Cover and Land Surface Temperature in Urban Areas: A Case Study in Geneva and Paris

Roberto Castello, Jean-Louis Scartezzini, Dasaraden Mauree, Xu Ge

Currently, more than half of the world’s population lives in cities, which leads to major changes in land use and land surface temperature (LST). The associated urban heat island (UHI) effects have multiple impacts on energy consumption and human health. A ...

An urban ecohydrological model to quantify the effect of vegetation on urban climate and hydrology (UT&C v1.0)

Gabriele Manoli, Matthias Roth, Paolo Burlando

Increasing urbanization is likely to intensify the urban heat island effect, decrease outdoor thermal comfort, and enhance runoff generation in cities. Urban green spaces are often proposed as a mitigation strategy to counteract these adverse effects, and ...

Impact of Escherichia colifrom stormwater drainage on recreational water quality: an integrated monitoring and modelling of urban catchment, pipes and lake

Frédéric Charles Soulignac

In recent years, recreational waterbodies are increasingly favoured in urban areas. In spite of the growing concerns for maintaining the required bathing water quality, the impacts of stormwater drainage are still poorly controlled. In this context, this s ...

Mapping urban underground potential in Dakar, Senegal: From the analytic hierarchy process to self-organizing maps

Michael Robert Doyle

This article presents a mapping method that seeks to provide urban planning with a diagnostic overview of the underground resources of an urban area. Resource potentials (for buildable space, groundwater or geomaterial extraction and geothermal energy) ten ...
