### Dataset and Embeddings Description

- **`pyg_{DEWP}_20_graph_step_1.zip`**  
  Contains the dataset used by the **baseline model**, which includes the **{DEWP}** feature and is implemented with **PyG (PyTorch Geometric)**.

- **`dgl_neighbor_10_step_1_refine_3.zip`**  
  Contains the dataset used by **MIGN**, including all available features in each file and implemented with **DGL (Deep Graph Library)**.  
  During training, only a single feature is used at a time.

- **`DEWP_embeddings_3.pt`**  
  Provides **3rd-degree spherical harmonics embeddings** for **station nodes** with the **DEWP** feature, used by MIGN.

- **`3_healpix_embeddings_level_3.pt`**  
  Provides **3rd-degree spherical harmonics embeddings** for **HEALPix nodes** at **refinement level 3**, used by MIGN.
