This paper presents a local climatological investigation of urban climate and urban structure carried out in Goteborg, Sweden. The surface and air temperature pattern are studied on a city scale and on a canyon scale. Data from ordinary weather stations and three specially designed weather stations are used. Recordings of temperature, humidity and wind are also made by an infrared thermography system (Thermovision 870), measurement cars and dataloggers. The geometry of the city is described by the sky view factor (SVF). In general the results show a lesser temperature variation than expected. The surface temperature varies a few degrees between different urban geometries, but the air temperature variation is very small. Further studies are planned to determine the temperature variation within the city and between the city and the suburbs.
