This project aims to translate the UT&C model to an open-source programming language which concurrently enables high computational efficiency and modularity. UT&C is a widely used urban climate model with a detailed vegetation scheme, thus being the perfect tool to inform urban greening strategies in cities around the world. However, the current code is written in a proprietary language and it is computationally heavy. By translating the UT&C code into Python and making it more open, FAIR, and user-friendly, this project will open up to new scientific opportunities (e.g., city-scale simulations, model coupling), facilitate a community-based development, and increase its accessibility to the broader urban climate and urban planning communities.
