dc.description.abstractResidents of urban areas are disproportionately affected by heat stress due to the combination of global warming and increasing urbanisation[1]. This not only affects the quality of life, but also poses a significant health risk and has been shown to lead to increased mortality rates[2]. However, due to the complex nature of urban climate, the impact of such interventions can vary depending on the local conditions and are thus hard to predict. In this study a real-world implementation of a spray mist cooling system in the city of Zurich is investigated. A ring carrying 180 high pressure nozzles was installed on a public square, as shown in figure 1a. Studies on spray mist cooling are scarce and inconclusive, as it depends on various operational, environmental and experimental factors[3]. State-of-the-art measuring stations[4] have been deployed for continuous measurements of temperature, humidity and other parameters during summer 2022, as shown in figure 1b. The measurements showed a weak cooling effect that was most pronounced south of the cloud, as shown in figure 2. A mean effect of -0.7°C was measured, with the strongest cooling of up to -2.5°C. The impact of the cloud was most pronounced at 25°C. A dependency on relative humidity and wind direction was measured, with the largest effect measured at low relative humidity downwind of the misting system. Outside of the operational hours no temperature difference was observed. The field experiment supports model development as an ideal case for model validation. The effect of the misting systems on heat and moisture fluxes have been implemented into the urban LES model PALM[1]. The parameterised cooling system in PALM was then used to investigate variations in placement, weather conditions and amount of sprayed water.de_CH
