Science and Technology on a Mission!
For more than 60 years, the Lawrence Livermore National Laboratory (LLNL) has applied science and technology to make the world a safer place.

We have an opening for an atmospheric scientist to work on atmospheric flow, transport and diffusion problems in the National Atmospheric Release Advisory Center (NARAC) (http://narac.llnl.gov), a national support and resource center for emergency response and analysis of hazardous atmospheric releases. You will be in the Atmospheric Flow, Transport and Hazard Assessment group within the Atmospheric, Earth and Energy Division.

Essential Duties
- Create atmospheric dispersion modeling calculations quickly and accurately using the NARAC modeling suite.
- Implement Weather Research and Forecast (WRF) simulations for an operational center.
- Provide consulting and regular, routine scientific support to and for users of NARAC.
- Generate customized real-time weather forecasts and hindcasts of historical meteorological conditions with the WRF model.
- Serve on the team for monthly on-call rotation in the NARAC Operation Center.
- Develop and document standard operating procedures for the operations team.
- Perform other duties as assigned.

Qualifications
- MS in meteorology, atmospheric science, or closely related field, or the equivalent combination of education and related experience.
- Comprehensive knowledge of synoptic and mesoscale meteorology and numerical weather prediction.
- Broad experience compiling, configuring, and running a mesoscale meteorological mode, such as WRF, and interpreting the results.
- Comprehensive understanding of available atmospheric reanalysis and observation data products.
- Broad experience assimilating weather observations and gridded analysis products into WRF simulations using Four Dimension Data Assimilation (FDDA) or variational methods.
- Experience applying microscale, boundary layer or air pollution meteorology theories in order to solve moderately complex problems.
- Proficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information.
- Ability to travel to coordinate research with collaborators.

Desired Qualifications
- Experience generating probabilistic ensembles using numerical weather prediction simulations with varying model physics, initial conditions, and parameter settings.
- Experience with programming languages including Fortran, Python, Java and C++.
- Experience running atmospheric dispersion models (e.g., AERMOD, CALPUFF, CMAQ, FLEXPART).

 

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.  This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance:  This position requires a Department of Energy (DOE) Q-level clearance.
If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing.  Q-level clearance requires U.S. citizenship.  If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.

Note:   This is a Career Indefinite position. Lab employees and external candidates may be considered for this position.
