Research Areas

Urban climatology

Research Interests

My academic training is in physical geography and boundary layer climatology and meteorology. My current research combines surface and boundary layer meteorology and climatology with remote sensing and GIS. It focuses on the importance of the surface.

• Thermal remote sensing of urban areas and the use of remote sensors to estimate urban surface temperatures.
• Observation and modeling of urban thermal anisotropy.
• Application of thermal remote sensing to the study of surface climates.
• Modeling urban surface temperatures.
• Methods of climate measurements in urban areas, especially traverse methodologies for gathering climate data.
