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经济问题， 环境的规模变化。 虽然地方和区域 气候变化一般包括在这一主题中， 这种研究往往集中在微观尺度的研究， 城市峡谷 中尺度模式考虑了大气的边界层， 空气和城市的整体改造。最近 遥感技术、地理信息系统 信息系统和能量平衡模型允许 土地利用信息与遥感地表匹配 温度数据在适当的分辨率范围内， 与沙漠都市有关的气候变化 发展可以分析。 本项目将研究 城市发展与气候变化之间的因果关系 利用地表温度，反射率，植被指数， 热惯性和亚利桑那州凤凰城目前的土地使用情况 大都会区。 遥感图像，气候记录， 计算机建模和实地工作将被用来了解 城市结构和邻近地区之间的复杂关系 不同分辨率下的地面和边界层气候 空间尺度 这项研究将改善现有的城市模型， 通过分析不同来源的数据来改变气候， 相同的空间尺度，允许更精确的 人类活动对气候影响的评估 表面的条件。 利用凤凰城地区作为 设计和测试评估土地使用方法的实验室 气候条件的变化将有重要的延伸， 世界上极端敏感的干旱和半干旱地区。

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.
