The training parts of WHUS2-CRv dataset in which the paired cloud and cloud-free Sentinel-2 images are from different regions of the world. The types of land cover are rich and the acquisition dates of the experimental data cover a long time period (from 2015 to 2020) and all seasons. The validation and testing parts can be found on: https://doi.org/10.5281/zenodo.8035349 If you use this dataset for your research, please cite us accordingly: #Reference: [1]J. Li, Z. W, Z. Hu, J.
