EMPIAR (https://empiar.org/ or https://www.ebi.ac.uk/empiar), the Electron Microscopy Public Image Archive, is a public resource for raw images underpinning 3D cryo-EM maps and tomograms (themselves archived in EMDB). EMPIAR also accommodates 3D datasets obtained with volume EM techniques and soft and hard X-ray tomography. All data archived in EMPIAR can be re-used freely without any conditions or restrictions ("CC0" license model).
Contains 3D cryo-EM tomographs and maps, volume-em data sets , or hard and soft X-Ray tomography. FIB-SEM, SBF-SEM
It also contains CLEM Correlative Light Electron Microscopy experiments... See the experiment list EMDB < Search results (ebi.ac.uk) for full list of modalities.
