Abstract
In spite of a long history of use of satellite thermal imagery in urban climate studies, many researchers believe that the thermal infrared (TIR) data is the most under- utilized. There is great potential to improve land surface temperature analyses and to enhance the studies on urban heat islands. No single satellite system currently provides thermal TIR data of global coverage that combines both high spatial and high temporal resolutions appropriate for urban climate studies. Based on the strengths and limitations of existing polar-orbiting and geostationary satellites, this lecture introduces key methods to maximize the use of TIR data to generate daily and hourly synthetic LST and other biophysical variables at the resolutions suitable for urban analyses and modeling. Specifically, this study illustrates three interconnected data fusion and mining techniques for TIR imagery: (1) A spatio-temporal data fusion technique for generating daily synthetic LST data at 120-m resolution by integrating Landsat TM and MODIS data; (2) A thermal downscaling technique to improve the synthetic LST data to 60-m resolution; (3) a data mining method for modeling long-term LST climatology. Examples of application using these synthetic datasets and techniques will also be presented.
