 RealPDEBench is a benchmark of **paired real-world measurements and matched numerical simulations** for complex physical systems. It is designed for **spatiotemporal forecasting** and **sim-to-real transfer** evaluation on *real data*.
 
 This Hub repository (`AI4Science-WestlakeU/RealPDEBench`) is the **release repo** for RealPDEBench.
