Air pollution dispersion inside a street canyon of Göttinger Strasse (Hannover, Germany): New results of the analysis of full scale data
(Inderscience Enterprises, 2010-01)
This study analyses the interactions between pollutant concentrations inside a street canyon, and wind and traffic dispersive air motions. Air pollutant concentrations, meteorological parameters and traffic flow continuously ...
CARBON MONOXIDE CONCENTRATION IN A STREET CANYON OF BUENOS AIRES CITY (ARGENTINA)
The analysis of three years of 8-h CO concentration values registered in a deep street canyon downtown shows high frequency of values that exceed WHO health protection guidelines. An inverse relationship between opposing ...
A simple model for calculating air pollution within street canyons
This paper introduces the Semi-Empirical Urban Street (SEUS) model. SEUS is a simple mathematical model based on the scaling of air pollution concentration inside street canyons employing the emission rate, the width of ...
Intercomparison of atmospheric dispersion models applied to an urban street canyon of irregular geometry
(Taiwan Association for Aerosol Research-Taar, 2018-03)
The NOx concentrations measured at the sampling site of Cordoba Avenue, Buenos Aires City, characterised by an irregular geometry on both sides of the street, are used to intercompare results of five urban street canyon ...
Shadowing Correlation: Empirical Results for mm-Wave Wireless Links in Urban Street Canyons
To the best of our knowledge, this letter reports the first measurement campaign aimed at modeling the empirical large-scale/shadowing decorrelation distance in urban street canyons at 60 GHz. The observed path-loss exponents ...
Numerical Study of Confined Explosions in Urban Environments
(Sage Publications, 2013-12)
In recent years, events such as the attack on the World Trade Center as well as many other attacks around the world have shown that terrorism related activity is dramatically increasing. Such a situation makes necessary ...
Outdoor-to-Indoor Empirical Path Loss Models: Analysis for Pico and Femto Cells in Street Canyons
The applicability of COST231, WINNER+, ITU-R, and 3GPP urban microcell outdoor-to-indoor path loss prediction models is empirically tested in 100 m radius urban femtocells. The analysis is based on more than 500 link ...
Modeling study of the aspect ratio influence on urban canopy energy fluxes with a modified wall-canyon energy budget scheme
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
The influence of the aspect ratio (building height/street canyon width) and the mean building height of cities on local energy fluxes and temperatures is studied by means of an Urban Canopy Model (UCM) coupled with a ...
Thermal bioclimate in idealized urban street canyons in Campinas, Brazil
(Springer WienWienAustria, 2014)
Impacto do adensamento e da orientação solar de cânions urbanos na demanda por condicionamento térmico de edificações sob condições de clima desérticoImpact of densification and solar orientation of urban canyons on energy demand for air-conditioning under desert climatic conditions
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2008)
