Cloud 3D - MSG/SEVIRI Finetuning Dataset

MSG/SEVIRI finetuning subset from the Global 3D Cloud Reconstruction Dataset. Contains colocated pairs of Meteosat Second Generation (MSG) SEVIRI geostationary imagery with CloudSat radar profiles for supervised 3D cloud structure reconstruction. Each sample includes: multispectral SEVIRI imagery (12 spectral channels + satellite/solar angles), CloudSat vertical profiles as ground truth, and a colocation mask indicating valid CloudSat footprint pixels. 256x256 pixel patches in Cloud-Optimized GeoTIFF format. Temporal coverage spans 2006-2020, providing the longest continuous record among the three geostationary sensors in the Cloud3D dataset.
