Vägbanetemperaturer i Lund

Sammanfattning: This paper is about road surface temperatures in the city of Lund, situated in the southern part of Sweden. The measurments were carried out during Febuary and March 1988. The temperature of the road surface and 0.1 and 2m above this, wind speed and direction were measured and the cloud cover estimated. Meteorological data were obtained from SMHI (the Swedish meteorological and hydrological institute). The results were divided into three different weather situations. Weather situation l represents clear weather with weak winds. Weather siruation 2 represents cloudy and windy weather. Weather situation 3 represents varied weather with more or less cloudiness. The results indicate that during weather situation l the lowest road surface temperatures appear at road stretches of high altitude and open to radiation losses. During weather situation 2 indicates that stations situated high and exposed to winds were coldest. But the results are not clear because the wind direction was not the same during the different measurements. During weather situation 3 wind protected stations open to radiation losses were coldest. The differences between the stations are wery small and the results must be considerd unsure. To get a clearer picture more measurements most be carried out during the differnt weather conditions.
