Postdoctoral Researcher – Modeling Cloud and Aerosol Physics and Chemistry


25 August 2021 - 28 September 2021

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, including secondary organic aerosol processes in 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 several other national and international universities and institutes.

Required qualifications:

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

Preferred qualifications:

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