New climate dataset from Mazovia (Central Poland) from the late 19th century as a basis for estimating the urban effect in multi-year trends in air temperature in Poland

Key Points

• Air temperature trends reveal significant urban effects over multi-year periods within Poland.
• The dataset indicates variations that support findings on local climate influences.
• Analysis of historical climate data highlights the need for improved urban climate modeling.
• Further validation is important to generalize findings across different regions.
