    Abstract

    The aim of this study is to identify and explain any differences in temperature between an urban area and urban parks within it. The area studied was the city of Portsmouth, UK, in which the temperatures of three parks of varying characteristics were compared to that of the surrounding urban area. Temperature data is recorded using 6 automatic temperature loggers recording temperature at 15 minute intervals between the 23rd November until 8th of December 2005 within 3 park and 3 urban sites. This study revealed the presence of both daytime park heat islands and nocturnal park cool islands of varying magnitudes within all three parks,the maximum daytime PHI recorded was 2.51oC and the maximum PCI was -3.19oC. Although temperatures were found to be on average cooler in the parks, clear diurnal patterns were identified in the temperature difference.There was also considerable variation in the behaviour of the three parks as a result of their varying characteristics and thermal response to factors such as wind speed and temperature change. To briefly summarise, the University Courtyard was dominantly warmer than the surrounding urban area, the Navy playing field experienced the most extreme negative temperature differences and had the largest range of temperature and Victoria Park was found to have the most consistent PCI and smallest temperature range.
