Land-use modifications due to urbanisation can modify the energy balance in cities; this, in turn, affects the urban thermal environment, resulting in the urban heat island (UHI) effect, whereby urban areas often experience different temperatures than surrounding rural areas. These land-use modifications vary across a city and it is important to capture this spatial variability when representing the urban environment in climate models. This presentation will deliver results from an urban land-use classification of Sydney using the World Urban Database and Access Portal (WUDAPT).  WUDAPT is designed to preserve the unique characteristics of cities in a relatively timely and cost-efficient manner, and allows for assessment of different urban land-use classes across cities globally. This land-use classification will be used to provide model parameter inputs to future urban climate model simulations for Sydney.
