Join us and make YOUR mark on the World! Lawrence Livermore National Laboratory (LLNL) has turned bold ideas into world-changing impact advancing science and technology to strengthen U.S. security and promote global stability.  Our mission spans four critical national security areas nuclear deterrence, threat preparedness, energy security, and multi-domain defense empowering teams to take on the toughest challenges of today and tomorrow. With a culture built on innovation and operational excellence, LLNL is a place where your expertise can make a real impact. We have an opening for an Atmospheric Science-Postdoctoral Researcher to work in the areas of clouds and precipitation with the goal of improving performance of global storm resolving models through evaluation and diagnosis using Department of Energy Atmospheric Radiation Measurement program observations. Research topics may include the mechanistic understanding of clouds, convection, precipitation and land-atmosphere interactions.   This is a two-year Postdoctoral appointment with the possibility of extension to a maximum of three years. This position is in the Atmospheric, Earth, and Energy Division which is part of the Physical and Life Sciences Directorate. This position may offer a hybrid schedule, blending in-person and virtual presence. You may have the flexibility to work from home one or more days per week. In this role, you will Conduct research on the processes governing the transitions in boundary layer turbulence, clouds, convection, precipitation, and land-atmosphere interaction. Diagnose and improve global storm resolving models using ground-based and satellite observations and machine learning. Perform modeling tasks using cloud resolving models or large-eddy simulations. Contribute to and actively participate in the conception, design, and execution of research to address defined problems. Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory. Collaborate with others in a multidisciplinary team environment to accomplish research goals.
