Numerical analysis of outdoor climate conditions based on the 3-years measurement for Zilina

The need for reference files resulted from the development of advanced simulation models. Few methodologies for creation of test reference years were developed in last decades. Most common are following two methods: a simple selection of worst year from recommended period or the numerical analysis of months and then the combination of months into one reference file, which in is not real, because the months are selected from various years. It is necessary to temper the connection of individual months. With the outdoor climate change and therefore the synthetically (combined) based reference years for many areas can not satisfy more and more advanced simulation models. Reference years are created from values measured mostly by weather stations belonging to the national weather forecast service, which is not very dense and the resolution and measured climate data are insufficient. Problems of urban heat islands in the cities is also widely discussed. In this paper, the outdoor climate characteristics measured by the mobile weather station located in the University of Zilina campus are analyzed. The station records most of the climate parameters required for HAM simulations since 2014. Measured data are also compared to data obtained from national weather forecast service stations located nearby.
