Recent research on global climate change has focused on global warming, desertification, deforestation and related macro- scale changes in the environment. While local and regional climatic modification has been included in this theme generally, such research has tended to concentrate on micro-scale studies of urban canyons. Meso-scale models consider the boundary layer of air and the city's overall modification of it. Recent advancements in remote sensing techniques, geographical information systems, and energy balance models permit the matching of land use information with remotely sensed surface temperature data at an appropriate scale of resolution so that climate modification associated with desert metropolitan development can be analyzed. This project will examine the causal links between urban development and climate modification using surface temperature, reflectivity, vegetation indices, thermal inertia, and current land use for the Phoenix, Arizona metropolitan area. Remotely sensed imagery, climatic records, computer modeling and field work will be used to understand the complex set of relationships between the urban fabric and near surface and boundary layer climate at varying resolutions of spatial scale. This research will improve upon existing models of urban climate modification by analyzing data from different sources at the same level of spatial scale, permitting more accurate assessment of the influence of human activity on climate conditions at the surface. The use of the Phoenix area as a laboratory to design and test methods for evaluating land use change on climate conditions will have important extensions to critically sensitive arid and semi-arid regions of the world.

最近关于全球气候变化的研究主要集中在全球变暖、荒漠化、森林砍伐和相关的宏观环境变化上。 虽然地方和区域气候改变通常包含在这一主题中，但此类研究往往集中在城市峡谷的微观尺度研究上。 中尺度模型考虑空气边界层和城市对其的整体修改。 遥感技术、地理信息系统和能量平衡模型的最新进展允许以适当的分辨率将土地利用信息与遥感地表温度数据进行匹配，从而可以分析与沙漠都市发展相关的气候变化。 该项目将利用亚利桑那州凤凰城大都市区的地表温度、反射率、植被指数、热惯性和当前土地利用来研究城市发展与气候变化之间的因果关系。 遥感图像、气候记录、计算机建模和实地工作将用于了解不同空间尺度分辨率下城市结构与近地表和边界层气候之间的复杂关系。 这项研究将通过分析同一空间尺度上不同来源的数据来改进现有的城市气候改变模型，从而更准确地评估人类活动对地表气候条件的影响。 使用菲尼克斯地区作为实验室来设计和测试评估气候条件下土地利用变化的方法，将重要扩展到世界上极其敏感的干旱和半干旱地区。
