| Description | The LCZ classification can be used easily and properly as a basic source of information about the nature of the area around station. However, in order to have a full standardization of the description of the neighborhood of a station, we must also standardize the classification procedures, including the methods used for the processing of spatial data. The classification of subclasses should also be defined in detail so that the LCZ classification takes into account any specific local features with outlosing its general applicability and practical usability. Within subclasses, the classification of LCZ should also distinguish the geometric layout of the area. Although the air temperatures varied greatly within a par ticular zone as a result of the nature of the development around the stations and insufficient standardization of the location of the stations in relation to a respective LCZ, it was clear that during the night hours, the air temperatures at stations located in the compact rise (LCZ 2) were higher than in the open rise (LCZ 4, 5, and 6), sparsely built areas (LCZ 9) and on the outskirts of the city (LCZ B). On the other hand, the maximum daily temperatures were lowest in the compact rise (LCZ 2) and higher in the open rise (LCZ 4, 5, and 6) and on the outskirts of the city (LCZ B). However, if the classification is to be used for comparing the temperatures between particular LCZs, it is necessary to follow more detailed recommendations regarding the location of the stations that are to represent a particular LCZ. |
