Post Doctorate RA

Pacific Northwest National Laboratory

Job Description

The Earth System Modeling group within the Atmospheric Sciences and Global Change Division at Pacific Northwest National Laboratory (PNNL) seeks a postdoctoral research associate to join a highly collaborative project for the design of a large-scale Aerosol-Cloud-Drizzle-Convection Chamber (ACDC2) to study interactions and evolution of aerosols and cloud droplets within turbulent clouds, including aqueous chemistry and drizzle formation processes. The successful candidate will join the team of PNNL scientists in using analytical and numerical models of different complexity to explore aerosol and cloud processes that would occur within the proposed chamber. Specific tasks will depend on applicant’s qualifications and may include conducting large-eddy simulations (LES) of the ACDC2; analyzing simulated cloud chamber thermodynamics and microphysics; evaluating modeled cloud and aerosol properties against observations from a prototype chamber; developing an improved cloud microphysics scheme; and performing aqueous chemistry modeling by implementing recently developed formulations of secondary organic aerosol chemistry into parcel and LES models. The project is part of a joint effort by the members of the Convection Cloud Chamber Consortium co-sponsored by the Department of Energy (DOE) Atmospheric System Research Program and the National Science Foundation (NSF) Physical and Dynamic Meteorology Program, and the successful candidate will have an opportunity to collaborate with partner scientists from the Brookhaven National Laboratory, Michigan Technological University, and seven other national and international universities and institutes.

Required qualifications:

  • A Ph.D. in Atmospheric Science, or a related field;
  • Demonstrated experience in one of the following areas:
    • Modeling of atmospheric processes;
    • Cloud and precipitation microphysics;
    • Aqueous aerosol and cloud chemistry.



Minimum Qualifications

Candidates must have received a PhD within the past five years (60 months) or within the next 8 months from an accredited college or university.

Preferred Qualifications

  • Strong interpersonal communication skills;
  • Demonstrated ability to publish work in peer-reviewed journals;
  • Willingness and ability to work both independently and in a collegial environment;
  • Fluency in Fortran;
  • Working knowledge of large-eddy simulation or direct numerical simulations models;
  • Experience with a size resolved, bin or particle-based. microphysics scheme;
  • Familiarity with high-performance computing environments.
