In urban areas, main air flows from prevailing winds are strongly modified, depending on constructions’ morphology and urban microclimate’s effects. The meteorological data on the wind speed are often available from outside city centres whereas this wind speed is tough to assess in the urban canopy layer. The meteorological models which are developed from regional level to urban canopy layer le...

Ongoing climate change is manifesting in the expansion of urban heat island (UHI) effect. This paper evaluates microclimate benefits cool pavements and green infrastructures a historical square Rome, Italy. The ENVI-Met software enabled us to conduct microclimatic analysis examined July 2021, through comparison thermal performances current asphalt sampietrini pavement (AS) with three alternativ...

Extreme heat is a leading cause of weather-related human mortality. The urban heat island (UHI) can magnify heat exposure in metropolitan areas. This study investigates the ability of a new MODIS-retrieved near-surface air temperature and humidity dataset to depict urban heat patterns over metropolitan Chicago, Illinois, during June–August 2003–13 under clear-sky conditions. A self-organizing m...

This paper describes urban wind ventilation mapping, using the concept of “building frontal area index”, and uses the Kowloon peninsula of Hong Kong as an example of a dense, sub-tropical urban environment where ventilation is critical for human health. The frontal area index is calculated for uniform 100 m grid cells, based on three dimensional buildings in each cell, for eight different wind ...

A web-based screening tool has been developed to assist urban planners and air quality management officials in assessing the potential of urban heat island mitigation strategies to affect the urban climate, ozone air quality, and energy consumption within their cities. The user of the screening tool can select from any of over 200 US cities for which to conduct the analysis. The mitigation stra...

An Aerodyne high resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) was deployed during the Carbonaceous Aerosols and Radiative Effects Study (CARES) that took place in northern California in June 2010. We present results obtained at Cool (denoted as the T1 site of the project) in the foothills of the Sierra Nevada Mountains, where intense biogenic emissions are periodically mixed...

Twenty-nine urban inhabitants participated in a half-day climatotherapy programme at the moderate mountain area and lowland area in the northwest part of the main island of Japan. The current study was aimed to investigate physically and mentally the objective and subjective influence of our short programme, which was a prospective pilot study of single intervention. Blood pressure was signific...

In contemporary urban development, to improve the quality of public urban spaces has become one of the most outstanding goals of local urban policies, in order to increase pedestrian activities and people’s social interaction. In this context, to promote outdoor thermal comfort has an utmost importance, especially considering the heat island phenomenon. This paper recalls the use of urban desig...
