Assessment of air temperature indices and urban heat island intensity nbased on two meteorological networks in Prague, Czechia

Popis výsledku v původním jazyce

The growing focus on studying urban climate has been driven by the broader interest in the impacts of climate change. Even though urban climate modelling continues to expand, in-situ measurements in urban areas remain irreplaceable. This study is the first to evaluate a set of measurements from a municipal network for climate monitoring (OICT), and data from the Czech Hydrometeorological Institute network (CHMI) in Prague (Czechia). Our study, based on data from n2023, shows the spatiotemporal variation in air temperature in the city, which results, on average, in minimum, maximum, and mean daily air temperature differences of up to 3.2 °C. The highest values of heat air temperature indices, as well as urban heat island intensity based on daily mean, minimum, and maximum temperature (UHII*), were recorded in local nclimate zones LCZ 2, LCZ 5, and LCZ 8, the lowest in LCZ B and LCZ D. The intrazonal spatial variability results from the specifics in solar irradiation at the station during the day, as well as from the characteristics of the surface, the relief, and the general “representativeness” of the parent LCZ class properties. Prague’s UHII* is spatially less extensive at night and has a different spatial pattern to the daytime conditions. The UHII* enhancement during the heat-wave period was nlow (0.1 °C on average). Comparing seasons, UHII* was 0.4 °C lower on average in winter than in summer. Such results demonstrate that the recently established network has the potential to contribute to our understanding of the (changing) nclimate in Prague.
