AER Emission Scientist Job Opportunity

Opportunity Overview: We are looking for an Emission Scientist who will work with AER’s Air Quality and Greenhouse Gas Teams[1] to develop bottom-up inventories of greenhouse gases (GHGs), ozone precursors, aerosols, and other air pollutants for a variety of scientific applications, including carbon cycle studies, atmospheric chemistry research, air quality and climate modeling, and air pollution control strategy development. Experience with using tools like SMOKE and MOVES to convert these emission inventories into gridded, speciated, hourly emission inputs for air quality and atmospheric dispersion models is required, and experience with top-down inversion methodologies to evaluate and improve emission inventories is a plus. The Emission Scientist will also be expected to pursue relevant funding opportunities in order to develop an externally funded research program, and to regularly present at scientific conferences and publish results in peer-reviewed journals. You will be able to use the extensive imagery, business activity, and other data sets produced at AER and our sister Verisk Analytics companies to provide innovative, industry-leading solutions for the emission inventory and emission modeling needs of clients in government, academia, and industry, as well as to further your own scientific research interests. The position requires individuals that have a passion for collaboration across teams and divisions, leveraging their technical and scientific skill to inspire creativity across the organization.  Interested applicants should include a cover letter with their application detailing why you feel you are a good fit for this role and precisely how your prior experience and technical skill set match the job requirements.

Qualifications Include:

  • A graduate degree in the physical sciences or engineering (e.g., Chemistry, Meteorology, Physics, Environmental Engineering, Chemical Engineering, Mechanical Engineering) that included coursework and research projects relevant to the Emission Scientist position
  • 2+ years of practical work experience with emission inventory development and emissions modeling


  • Support AER’s Air Quality and Greenhouse Gas Teams through emission inventory data development, inventory assessment, control strategy assessment, and emission modeling
  • Work may include:
    • Collection and processing of activity and emission data for use in inventory development
    • Development of relevant emission factors
    • Development and application of growth rates
    • Developing spatial and temporal profiles for different emission sectors
    • Control technology assessment
    • Regulatory analysis
  • Develop and lead an externally funded research program on emission modeling, the Earth’s carbon and nitrogen cycles, or other relevant scientific topics
  • Author scientific reports and journal articles
  • Present at scientific and industry conferences
  • Maintain active, positive, and productive relationships with clients and collaborators

Technical and Scientific Skills:

  • Expertise with bottom-up emission inventory development
  • Expertise in using models like SMOKE and/or MOVES to prepare emission inputs for air quality models like CMAQ, CAMx, or WRF-Chem
  • Expertise with GIS data and tools
  • Expertise using inversion methodologies to create top-down emission estimates of GHGs and other air pollutants
  • Excellent scientific programming skills in FORTRAN and other languages (e.g., Python, R, Perl, IDL)
  • Excellent writing skills
  • Strong scientific understanding of the biogeochemical cycles of carbon and nitrogen and how they influence atmospheric composition is a plus
  • Experience with 3D Eulerian air quality models (e.g., CMAQ, CAMx, or WRF-Chem) or Lagrangian particle dispersion models (e.g., HYSPLIT, STILT, FLEXPART) is a plus
  • Ability to work in a fast-paced multidisciplinary environment
