N1 - Funding Information: The urban climate model adopted to this study is the PALM 6.0 model system. This model system is developed to be a modern and highly efficient model allowing for simulations over large domains (neighbourhood and city scale) with building-resolving spatial resolution (Maronga et al., 2019). It is based on the well-established large-eddy simulation (LES) PALM version 4.0 (Maronga et al., 2015). The model is further developed within the framework of the first phase of the funding programme “[UC2] – Urban climate under change”, funded by the German Federal Ministry of Education and Research (BMBF), to enhance the components needed for the application in urban environments (so-called PALM-4U components), such as interactive building surface and air quality schemes. Within the second phase of [UC2], PALM-4U is further developments to enhance its physical implementations, evaluation, and practicability. The model is briefly described below; however, for a detailed description, readers are advised to refer to Maronga et al. (2020). Funding Information: This research has been supported by the Federal Ministry of Education and Research (Germany) (grant no. 01LP1601A), the European structural and investment funds (grant no. CZ.07.1.02/0.0/0.0/16_040/0000383), Norway Grants, and the Technology Agency of the Czech Republic "Turbulent-resolving urban modelling of air quality and thermal comfort" project (TURBAN, project no. TO01000219). This study is funded by the German Federal Ministry of Education and Research (BMBF) under grant no. 01LP1601A within the framework of Research for Sustainable Development (FONA; http://www.fona.de, last access: 27 December 2021), which is greatly acknowledged. The German Aerospace Centre (DLR) Project Management provided the input data for the realistic urban configuration. Simulations have been performed at the supercomputers of the North-German Supercomputing Alliance (HLRN), which is gratefully acknowledged. The co-authors, Jaroslav Resler and Pavel Krˇc, were supported by the project CZ.07.1.02/0.0/0.0/16_040/0000383 UrbiPragensi – Urbanization of weather forecast, air quality prediction and climate scenarios for Prague under the programme OP PPR "Prague – Growth Pole of the Czech Republic" which is co-financed by the EU. Their financial support was also provided by Norway Grants and the Technology Agency of the Czech Republic "Turbulent-resolving urban modelling of air quality and thermal comfort" project (TURBAN, project no.
