| Research Abstract |
Urban heat island measurements had been performed in Tsukuba city in summer and winter during the past three years for 2008-2010. In the measurements, 30 measuring instruments with thermometers and radiation shelter were set in the parks and roads in the city. The observed results showed that the urban heat island intensity (UHII) in August 2010 and January 2010 is 1.6 ℃ and 0.8℃, respectively. Additional observations showed that temperature in a large park is colder than that in a small park and there was almost no difference in the temperature between small parks and its surrounding roads in the housing area. Distribution of surface air temperature in Tsukuba city is determined by the superposition of urban-scale heat island effect and local-scale land-use impact.
