temperature reduction. This aim is achieved using models with different spatial
resolutions and designing exemplary measurements for case studies. All these
results and information are demanded and can have a direct application. However,
it has to be mentioned that results of thermal indices (PET or UTCI), compared to
studies based only on air temperature, produce different outcomes. For example,
increasing albedo of urban surfaces can decrease air temperature, but at the same
time it increases the values of PET, due to increased shortwave reflection. This is a
relevant topic not only during summer, but throughout the all year, because it affects
the use of the urban spaces, where people want to spend time outdoors.
Finally, easy understandable graphs and figure are a possibility for better communication between different users and disciplines.
