CIRES​/NOAA Chemical Sciences Laboratory, Research Scientist in Atmospheric Modeling and Data

Job Summary

The Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado seeks a Research Scientist to join the Stratospheric Modeling and Analysis (SMA) Program of the National Oceanic and Atmospheric Administration's Chemical Sciences Laboratory (CSL) in Boulder, Colorado. Our group uses a variety of models and observations to study the complex relationships between stratospheric composition, chemistry, dynamics, and radiation, and how these processes affect weather and air quality.

If hired, you will work closely with a team of federal and CIRES scientists to improve an in‑house satellite stratospheric composition dataset, support new chemical forecast development and validation, and conduct scientific analyses of coupled stratospheric processes. The role involves working with large satellite and model data sets, chemistry–climate modeling on a supercomputing platform, and likely machine learning development for scientific applications.

• Participate/lead in UFS‑chem validation/development efforts, particularly with relation to stratospheric aerosols, ozone, and water vapor (40%)
• Evaluation of stratospheric ozone/water vapor/aerosol biases in comparison to observations (e.g., SWOOSH, SAGE III/ISS, OMPS), including episodic events such as volcanic eruptions
• Targeted UFS‑chem experiments to test potential improvements in stratospheric composition, and process studies to understand whether improved stratospheric composition and/or dynamics improve forecasts
• Develop and implement improvements to the SWOOSH multi‑satellite water vapor and ozone data record, with a specific focus on SAGE III/ISS data and ensuring reliability of the long‑term record (55‑60%)
• Evaluate new and updated satellite data sets for inclusion into SWOOSH
• Improve data screening, screening homogenization, and uncertainty characterization
• Use SWOOSH, SAGE III/ISS, and complementary data sets for improved quantification and process‑level understanding of decadal variability and trends in stratospheric composition and circulation
• Perform other relevant duties as necessary (not to exceed 5%)

• This is a 2‑year position with the possibility for extension
• The position is rostered in CIRES at the University of Colorado Boulder but will be physically situated in the David Skaggs Research Center, 325 Broadway, Boulder, CO 80305, on a federal research campus
• Selected candidate must provide proof of dissertation submission and successful defense prior to start date
• Selected candidate must pass a federal laboratory background clearance for site access

• Ph.D. in atmospheric science or a related field (required)
• Experience with atmospheric chemistry, radiation or dynamics (required)
• Experience with statistics and numerical modeling (required)
• Expertise with satellite and model data analysis (required)
• Computer programming skills in Python, IDL or another scientific programming language (required)
• Strong ability to communicate results in written and oral form (required)

• Ability to rapidly learn and effectively apply new knowledge and skills
• Strong interest in advancing scientific understanding through simulations and observations
• Ability to work independently and collaboratively
• Experience with machine learning

• CIRES offers a generous compensation package
• Annual salary range for this position is $72,000 – $84,450
• Relocation funds available to help offset expenses
• Hybrid work modality possible
• Robust training curriculum and professional development opportunities
• Boulder community amenities including parks, trails, and cultural venues
