NGDC provides stewardship, products and services for geophysical data describing the solid earth, marine, and solar-terrestrial environment, as well as earth observations from space. NGDC's data holdings currently contain more than 400 digital and analog databases, some of which are very large, and the center works closely with contributors of scientific data to prepare documented, reliable data sets.
