Pacific Northwest National Laboratory Post Doctorate RA - Cloud microphysics parameterization in RICHLAND, Washington

Organization and Job ID

Job ID: 309931

Directorate: Earth & Biological Sciences

Division: Atmospheric Sciences & Global Change

Group: Advanced Study & Development

Job Description

The Atmospheric Sciences and Global Change Division at Pacific Northwest National Laboratory (PNNL) seeks a postdoctoral research associate to work on the development and evaluation of cloud microphysics parameterization for the U.S. Department of Energy’s (DOE’s) Energy Exascale Earth System Model (E3SM), as part of the “Enabling Aerosol-cloud interactions at GLobal convection-permitting scalES (EAGLES)” project. Targeted at DOE’s leadership computing facilities (e.g., GPU-based systems), the EAGLES project seeks to develop scientifically robust and computational efficient parameterizations to represent aerosols and aerosol-cloud interactions with a focus on liquid clouds.

The selected candidate will work with the EAGLES team to advance the understanding and representation of cloud microphysical processes and cloud-aerosol-precipitation interactions. Development will be guided by observations and spectral bin microphysics (SBM) model simulations from the high-resolution Weather Research and Forecasting (WRF). In addition, the selected candidate will work with the EAGLES team on improving the computational efficiency of cloud microphysical calculations.

The candidate should have demonstrated expertise in modeling cloud microphysical processes and working knowledge of bulk and/or explicit cloud parameterizations used in atmospheric models. Proficiency with FORTRAN and coding experience with atmospheric models are required. The ability to modify, compile, and run E3SM and WRF is desirable. Experience with C++ and running on GPU-based supercomputers is a plus. Teamwork and strong communication skills for engaging with project teams at PNNL and the broader climate research community are also essential.

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

PhD in relevant field is required with strong experience/background in (1) understanding and parameterizing cloud microphysical processes and cloud-aerosol-precipitation interactions, (2) FORTRAN proficiency and ability to modify and run 3-D weather forecast or climate models, and (3) use observational techniques (such as simulators) and data to understand and improve cloud parameterization.

A successful candidate will also need:

  • Strong communication (written and oral) skills

  • Strong programming skills

  • Technical writing skills

  • Enthusiasm

  • Strong team player with the ability to work independently

  • Leadership potential

Ph.D. degree in Atmospheric Sciences or related field.
