Short summary
This paper introduces a high-resolution dataset of daily air temperatures in Poland from 1951 to 2020 with a 1 km2 spatial resolution. The PL1GD-T dataset was developed using radial basis functions applied to quality-controlled observations from ground weather stations and evaluated using cross-validation methods. This open-access dataset is crucial for climate change impact studies on a smaller scale and can serve a wide range of users, including researchers, administrative bodies, and society.
