The mission of SEES (Synchrotron Earth and Environmental Science) is to advance research and education in synchrotron-based Earth and environmental science to better understand our planet from the atmosphere to the core, to address societally relevant problems, and to train the next generation of scientists. SEES is responsible for the management, operation, and development of multiple user facilities hosted at four DOE-operated US synchrotrons: Advanced Photon Source (APS), Advanced Light Source (ALS), National Synchrotron Light Source II (NSLS-II), and Stanford Synchrotron Radiation Lightsource (SSRL).
