| Methane is the second-largest driver of anthropogenic warming, and a disproportionate share of emissions comes from a small number of super-emitters detectable by satellite. MethaneSET provides analysis-ready datasets for methane plume detection spanning three sensors with expert-verified segmentation masks from two independent monitoring systems (IMEO MARS and Carbon Mapper). For multispectral sensors (Sentinel-2, Landsat-8/9), labeled scenes with plume masks and confirmed plume-free references are provided for change-detection workflows. For the EMIT imaging spectrometer, calibrated radiance cubes and precomputed matched-filter products support both end-to-end and retrieval-based detection. A synthetic plume bank of over one million WRF-LES enhancements enables physics-based data augmentation. All datasets follow the [TACO specification](https://github.com/tacofoundation/tacoreader) and are distributed as Parquet catalogs with Cloud-Optimized GeoTIFFs. |
