Our Current Projects

Earth and atmospheric research at LLNL spans multiple areas where our scientists collaborate with colleagues and leverage world-class research tools to explore how to make our planet safer and more resilient.


seismic models


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, expanding our understanding of how changes in complex ecosystems will impact U.S. energy resources — such as how air and water temperature changes can strain energy grids. LLNL also led a multi-lab effort to develop the Simple Cloud Resolving E3SM Atmosphere Model (SCREAM), the first global cloud-resolving model to run on an exascale supercomputer.


CO2 Direct Capture and Storage


Carbon dioxide removal at the gigaton scale

We collaborated with a dozen institutions to assess options for carbon dioxide (CO2) removal from the atmosphere and chart a path for the nation to achieve net-zero greenhouse gas emissions by 2050. The Roads to Removal report analyzes the feasibility, capacity and cost of CO2 removal techniques, including many studied at LLNL, such as biomass conversion and storage, direct-air-capture technology, soil and forest management and geologic CO2 storage. The report’s findings highlight region-specific solutions that can help the nation reach its climate goals.


Our Facilities, Centers and Institutes
