Cloud Coverage-Annotated Sentinel-2 Dataset (Based on SEN12MS-CR)

This dataset provides cloud-percentage annotated Sentinel-2 image tiles derived from the SEN12MS-CR dataset. For each cloudy Sentinel-2 image tile, a continuous cloud-coverage value (0–100 %) was computed and recorded, together with the acquisition season and, a reference clear-sky image tile. All metadata are stored in a single master CSV file to facilitate transparency, ease of access and reproducibility. The dataset contains: Cloud-obstructed Sentinel-2 images grouped by season (Spring, Summer, Autumn, Winter). Corresponding clear reference images. A master CSV file linking each image to its computed cloud-coverage percentage and season. This resource enables the benchmarking and evaluation of cloud-removal methods, geospatial scene reconstruction, and related machine learning studies under varying cloud conditions.
