Geographical Information Systems (GISs) can be seen as a common tool to map and visualize the air quality index based on geographical locations. However, in urban areas, the area resolution for air quality models is less than 2 kilometres. Since the main emissions agent in urban areas is predominantly vehicular engines, the situation will become worse when pollutants are trapped between buildin...

A directional wideband measurement campaign was performed in urban macrocells at 2 GHz using a channel sounder and a 8-sensor linear antenna array at the base station. Directions of arrival at the Base Station (BS) were estimated by beamforming using the antenna array. Directions of arrival at the Mobile Station (MS) were estimated by beamforming using parts of the measurement route. Global par...

Due to rapid urbanisation, urban microclimate research has become increasingly popular in the last decade. Significant variation conditions can be created due diversity geometry and it affect outdoor thermal comfort. Biometeorological measurements survey were conducted different settings (square, park, street) of city Novi Sad during a warm autumn day October 2019. Air temperature, relative hum...

• The impact of urban fabric on street canyon albedo was experimentally investigated. A detailed 1:10 scaled physical model a residential area in London developed. Canyon varies diurnally, seasonally, with cloud coverage and rainfall. Glazed façades lead to lower than brickwork aluminium cladding. Brickwork contribute higher the infrared. This paper presents findings from large-scale experiment...
