Urban climate modelling is essential to reveal the trend of the urban heat load caused by the climate change. Within the project “Urban climate in Central European cities and global climate change” (IVF-21410222) we examine the impact of global warming on Central European cities. Therefore we perform modelling analyses of possible future changes of urban climate in four cities in Hungary, the Czech Republic, Slovakia and Poland. For this analysis we use the urban climate model MUKLIMO_3. Different input datasets are necessary to describe the model domain. The so-called Land Use Table determines the land use characteristics of the study area. This table includes land use classes, and for each class there are 26 physical parameters (building fraction, wall area index etc.). Another input data is the Land Use File, which contains the identification value of the land use class for every grid cell of the model domain. The advantage of this model is the possibility to use arbitrary land use classification system. The recently developed Local Climate Zones (LCZ) classification system can be a good choice for the land use information, because it is a climate-based land use classification system and it describes the physical conditions of the local-scale environment. It is not site specific, and the different classes represent different thermal reactions. We applied Bechtel’s method for mapping of the LCZ classes, using satellite data (Landsat 7, 8). In this paper we present this land use mapping process in the example of Szeged, Hungary and the preliminary results of the model.
