Job Description

We are excited to offer an opportunity for a Postdoctoral Researcher to conduct research studying troposphere-stratosphere dynamics including data analysis of satellite observations, developing techniques to retrieve atmospheric gravity waves and turbulence, and general circulation modeling.  Research projects require diverse skills in atmospheric observations and modeling, which often requires development of atmospheric simulation codes for improved performance. Familiarity with turbulence and gravity wave modeling and atmospheric physics parameterizations is desired.  You will work with a multidisciplinary team of scientists, engineers, programmers, and project managers to analyze new satellite data, apply new modeling capabilities, and perform satellite data acquisition to investigate small-scale atmospheric gravity waves and turbulence in the stratosphere. 

This position is in the Atmospheric, Earth & Energy Division, Atmospheric Science Research and Applications Group.

In this role you will 

  • Conduct creative research in the field of atmospheric modeling.
  • Develop, validate, and apply algorithms to retrieve atmospheric gravity waves and turbulence from stellar occultation satellite observations.
  • Develop, run, and validate computer models to simulate propagation of atmospheric gravity waves and circulation.
  • Analyze model and observational datasets relevant to stratospheric disturbances.
  • Document research by publishing papers in peer-reviewed journals and present technical results at scientific conferences.
  • Collaborate with others in a multidisciplinary team environment to accomplish research goals.
  • Perform other duties as assigned. 


  • PhD in atmospheric science, mechanical, civil or environmental engineering, computational science, geophysics, or a closely related field.
  • Experience in one or more of the following areas: atmospheric science, multi-scale or mesoscale atmospheric modeling, stratospheric turbulence, atmospheric gravity waves, general circulation modeling, weather modeling, or observational data analysis.
  • Familiarity with programming languages such as Fortran, Python, and MATLAB.
  • Experience with high performance computing or interest in learning this skill.
  • Experience conducting research in atmospheric science, engineering, or a closely related field.
  • Ability to travel as required to collaborate with researchers or attend meetings and conferences. 
  • Experience with large model and observational datasets, modern programming environments, and visualization techniques.
  • Proficient verbal and written communication skills, as evidenced by published results and presentations. 

Qualifications We Desire

  • Experience with numerical methods and modern model development practices.
  • Experience with the Weather Research and Forecasting (WRF) model or a general circulation model such as the Energy Exascale Earth System Model (E3SM).
  • Familiarity with atmospheric gravity waves including theory, observations, modeling.
  • Familiarity with uncertainty quantification, ensembles, and statistical analysis.
