Scaled Outdoor Measurement of Urban Climate and Health (SOMUCH)

Introduction | Data citation | Help

We conducted a series of scaled outdoor experiments in Guangzhou, P.R. China, known as the SOMUCH (Scaled Outdoor Measurement of Urban Climate and Health) experiment. The SOMUCH experiment provides controlled parameters for urban morphology, urban heat storage, building surface materials, and urban vegetation. By eliminating the interference of anthropogenic heat and surface heterogeneity, it significantly reduces observational uncertainties. The dataset includes idealized measurements of urban temperature, wind speed and energy flux. SOMUCH offers essential support for validating and enhancing urban canopy models and Computational Fluid Dynamics simulations. The dataset and its detailed description can be downloaded from here.
