Welcome to GUC Lab!

Research Theme

As cities worldwide continue to emerge and evolve,  the dynamic interaction between urbanization and the environment has become more complex and problematic. The complexities surpass social, cultural, and economic boundaries. Each city, with its own background climate and socio-economic condition, faces unique issues and responds differently to known adaptation and mitigation measures. To address this, scientific understanding of urban-climate interactions is needed across time and space. We aim to utilize the advancement of computational efficiency, numerical weather modeling, and remote sensing to deepen global understanding of urban-climate interactions. Our main works include regional-to-global urban climate & climate change investigations, urban hydro-meteorology, and GIS database constructions. Specific topics include, but are not limited to, the following:

  • Climate modeling of multiple cities at a global scale
  • Modeling or investigating dynamics of urban or population growth in high-spatial and annual scales
  • Urban heat island investigations (including observations) at a global scale
  • Investigating the potential of remote sensing technologies (e.g. satellite images, machine learning technology) to urban database construction, and development of models automating processes.
  • Global climate modeling to investigate urban and global climate interactions

Global Urban Climatology

Global Urban Climatology (GUC) is foreseen to be a subfield of urban climatology that aims to obtain a uniform understanding of urban climate across all developed and developing cities around the world, and to clarify the specific mechanisms behind the formation of any given city’s UHI (Varquez, 2016).  

Urban climate is a result of various physical (climatology or meteorology) and social interactions (urbanization) of the past. Investigations will involve various disciplines requiring collaborative efforts from experts outside of urban climate. Transdisciplinary research is needed to understand societal behavior (e.g. sociology, national or local-level environmental policy in cities) and complex geophysical processes (e.g. climate change) – all playing vital roles to urban climatology.
