Short summary

We collected detailed weather measurements at the Onsala Space Observatory in Sweden from 2009 to 2025. The data show a clear warming, especially in winter, and less rainfall over time. Notable events include very cold winters in 2009–2011 and a warm winter in 2019–2020. This long record helps understand local climate change and supports future environmental research.
