Seismic Clues to Underground Explosions

Our geoscientists analyze seismic signals to differentiate between natural phenomena such as earthquakes, man-made activities like mining and illicit nuclear explosions. This work supports our nation’s efforts to detect and deter the spread of nuclear weapons and verify international agreements. Our research teams develop new methods to analyze data provided by seismometer networks, enabling them to determine the type of event that generated the seismic signals as well as the energy release of the event.

Modeling Climate Change that Impacts Energy Security

We play a key role in one of the most powerful climate modeling tools available — the Department of Energy’s Energy Exascale Earth System Model (E3SM). E3SM links Earth system and energy models into a single system, enabling a better understanding of the future impact to U.S. energy resources from changes in complex ecosystems. For example, using supercomputers to analyze billions of data points, researchers study how air and water temperature changes can strain energy grids or how floods and droughts can affect power plant operations.

High-Altitude Atmospheric Science

We explore the stratosphere through observational data that can validate models to better understand high-altitude dynamics. Analyzing atmospheric tracers, researchers measure small-scale turbulence at high altitudes affecting the performance and payloads of hypersonic aircraft and re-entry vehicles. Work to develop a satellite-based sensing instrument to make in situ measurements complements related efforts to collect aerosols using stratospheric balloons; analyzing isotopes in the aerosols helps researchers better understand atmospheric motion.


Our Facilities, Centers and Institutes

The Laboratory is home to several state-of-the-art facilities and centers to help researchers tackle the hardest and most complex challenges related to earth and atmospheric science.
