This poster was presented at the Winter Simulation Conference (WSC 2022) in Singapore, December 11-14, 2022. This research is part of the multi-institutional Cooling Singapore 2.0 project, which aims to enhance Singapore’s resilience to urban overheating through the development of a Digital Urban Climate Twin (DUCT). The study involves comprehensive environmental data collection in Singapore’s urban and park areas to validate microscale climate models. These efforts are crucial for providing stakeholders with effective climate adaptation strategies to combat urban heat and enhance climate resilience.
