Short summary
We introduce a large and diverse dataset that supports the development of machine learning methods for studying Earth structures through surface wave dispersion curves. Existing research has been limited by the absence of such benchmark data. Our dataset includes both computer-generated and real-world examples, allowing models to be tested and compared in a consistent way. By making these resources openly available, we aim to advance research on the shallow and deep Earth.
