城市环境变暖对公共卫生的影响意味着规划者、设计者和卫生工作者有必要采取适当行动，以最大限度地降低未来气候情景下的风险。用户群体需要适当空间尺度的数据，以查明关键的脆弱领域。在2007年和2008年夏天，为了提供高空间分辨率的温度数据，对英国的一个大城市进行了热成像。空气温度结果显示，在理想的城市热岛（UHI）条件下，夏季白天（夜间）平均3A摄氏度（5A摄氏度）的城乡热对比。白天的表面温度热岛强度被发现超过10A摄氏度。测量的数据被用来推导出一个经验模型的空间温度模式的基础上的特点，土地利用，距离城市中心和建筑物的几何形状。该模型可用于提供决策者所需的千米以下分辨率的温度数据，并可提供一种缩小气候模型输出的机制。
The public health implications of a warming urban environment mean that appropriate action by planners, designers and health workers will be necessary to minimise risk under future climate scenarios. Data at an appropriate spatial scale are required by user groups in order to identify key areas of vulnerability. Thermal mapping of a UK urban conurbation was carried out during the summers of 2007 and 2008 with the aim of providing high spatial resolution temperature data. The air temperature results showed an average daytime (night time) urban-rural thermal contrast of 3A degrees C (5A degrees C) on summer days (nights) with ideal urban heat island (UHI) conditions. The intensity of the daytime surface temperature heat island was found to exceed 10A degrees C. The measured data were used to derive an empirical model of spatial temperature patterns based upon characteristics of land use, distance from urban centre and building geometry. This model can be used to provide sub-kilometre resolution temperature data which are required by decision makers and can provide a mechanism for downscaling climate model output.
