The effects of land cover on urban-rural and intra-urban temperature differences have been extensively documented. However, few studies have quantitatively related air temperature to land cover composition at a local scale which may be useful to guide landscape planning and design. In this study, the quantitative relationships between air temperature and land cover composition at a neighborhood...

during the recent decades, urban management in iran has increasingly confronted numerous challenges due to different kinds of social, cultural, political, executive, financial, and legal factors. the present study is going to specify and analyze the aforementioned challenges in the domain of the urban environment in order to determine how far they have been effective, how they have been priorit...

conclusions every 10 μg/m3 increase in the concentration of the pollutant no2 in the studied cities led to increase in the rr of myocardial infarction, cardiovascular diseases, and obstructive pulmonary disease by 0.4%, 0.2%, and 0.4%, respectively, in 2011. higher rr value can depict mismanagement in urban air quality. the lower level of rr value might be achieved if some control strategies fo...

The goal of this study is to improve our understanding of the interactive function of impervious and vegetation covers at different levels of the local and intra-urban spatial scales in relation to air temperatures in an urban environment. A multiple regression model was developed using impervious and vegetation fractions at different scales to predict maximum air temperature for the entire Pho...

Air pollution is a major factor of consideration in the evaluation of quality of life and as an environmental issue in urban areas. Among urban air pollutants carbon monoxide (CO) is one of the most prevalent. Information about its concentrations is vital in the determination of urban air pollution. In this paper, an automatic and cost effective prototype for CO monitoring and mapping is presen...

Exposure to air pollution in city centers is of major concern because of its health-risks to urban dwellers, trafficcorridor users and even to in-transit commuters. The steady growth in traffic is the major source of toxic air pollutants in urban centers these days. Therefore, studying exposure to air pollutants in urban centers is of special interests to environmental health scientists. This s...

The substantial reduction in air pollution, and particularly in components such as benzo[a]pyrene in urban areas of the United Kingdom during the past few decades has presented an opportunity to consider further the possible role of carcinogens in the air in relation to lung cancer. While the overall trends in lung cancer mortality have undoubtedly been dominated by changes in smoking, the mark...

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...

Urban green roofs are discussed as a local climate adaptation measure to limit surface warming and increase evaporative cooling by vegetation in urban environments. A five month measurement campaign was conducted to observe surface and air temperatures as well as dewfall dynamics and amounts on an urban green and co-located bitumen roof. Measurements were performed in the period from August to ...

The indoor and outdoor particulate concentration and its chemical composition in six monitoring stations and selected residential dwellings were studied in May 2010 in Kathmandu valley. The six stations were strategically located to measure the air quality of the valley viz. -urban roadside, urban hospital, urban residential, urban background and valley background. Particulate concentration was...
