Pacific Northwest National Laboratory Post Doctorate RA - Modelling atmospheric ice-nucleating particle sources and concentrations in RICHLAND, Washington

Organization and Job ID

Job ID: 308774

Directorate: Earth & Biological Sciences

Division: Atmospher Sci's & Global Chg

Job Description

Pacific Northwest National Laboratory (PNNL) is recruiting a creative, energetic, and collaboration-oriented postdoctoral scientist with a background in modelling atmospheric constituents (aerosols / trace gases), for research to advance understanding of ice-nucleating particles (INPs) in the atmosphere.

The natural and anthropogenic sources of atmospheric INPs, their spatiotemporal variability in the atmosphere, and the implications of their variability for cloud phase, still present major unresolved challenges to atmospheric science. Sources of INP differ from overall sources of aerosol mass and number, and they exhibit large variability in time and space, making their measurement, attribution and simulation a challenging problem.

Our project will analyze recent and new measurements of INP source particles and atmospheric concentrations, using a measurements-to-models approach to advance understanding of these sources. The successful candidate will develop and conduct model simulations of the sources, transport and removal of atmospheric particles that can act as INP in the atmosphere. Research goals may include attribution of atmospheric aerosol and INP sources during field campaigns, understanding effects of atmospheric processing on INP activity of particles, advancing understanding of spatiotemporal variability in INP concentrations and its implications for cloud phase, and model evaluation using observed aerosol and INP properties.

The successful candidate will be expected to publish scientific results in peer-reviewed journals, to communicate research results at conferences and workshops, and to interact effectively with a rich network of experts in aerosol measurement and modelling at PNNL as well as other national laboratories and universities.

This is a full-time position anticipated to last for two years (contingent on performance), and starting as soon as possible.

Applicants should apply using the PNNL online application system, and provide (1) a cover letter, (2) a current CV, and the names and (3) the names and contact information of three professional references. Review of applications will begin after the position has closed.

Please contact Dr. Susannah Burrows ( ) with any questions about the position.

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

Minimum Qualifications

  • Experience with running, analyzing and possibly modifying global or regional atmospheric models (e.g., Chemical Transport Models, Climate and Earth System Models, or similar classes of models)

  • Excellent written and oral communication skills in English

  • Ability to work collaboratively in interdisciplinary teams as well as ability to independently pursue original ideas and new directions

  • Interest in contributing to an active intellectual environment

  • Demonstrated record of publications in peer reviewed journals

Preferred Qualifications

Applicants who have skills and experience in some of the following areas, and who are interested in developing new skills in additional areas, are encouraged to apply:

  • Demonstrated expertise in atmospheric tracer transport and numerical representations of aerosol microphysical processes

  • Familiarity with high performance computing, and statistical analysis methods

  • Familiarity with experimental methods for characterizing aerosols and ice-nucleating particles

  • Experience with computer languages usually used for climate modeling and analysis (Fortran, Python, R, NCL, or other analysis languages)

  • Familiarity with Linux/Unix computational environments

  • Ability to think critically and develop and test hypotheses using a combination of measurements and models

PhD in Atmospheric Science, Meteorology, Physics, Applied Mathematics, Statistics, Engineering, or a related field.
