Research Scientist Position: Assimilation of Upper Atmospheric Observations in NASA Assimilation Models
The Goddard Earth Sciences Technology and Research II (GESTAR II) consortium at NASA’s Goddard Space Flight Center (GSFC) invites applicants with a background in the fields of Atmospheric Science or Data Assimilation for a position focused on data assimilation in the middle and upper atmosphere. Research will be conducted as a part of the Global Modeling and Assimilation Office (GMAO), in close collaboration with the Ionosphere, Thermosphere and Mesosphere Lab in the Heliophysics Division.
Research in the GMAO emphasizes use of satellite observations to address questions that include weather analysis and prediction. Global ocean, ice, land-surface and atmosphere models are developed as components of assimilation and forecast systems, as well as for addressing the weather and climate research questions identified in NASA’s science mission. Research includes topics such as the generation and analysis of comprehensive model-based analyses that support studies of variability and change.
The work contributes to a major project between the Earth and Heliophysics Science Divisions at NASA GSFC, which is developing an analysis and prediction system that extends from the surface of Earth to the edge of space. The work of the successful candidate is expected to be fully integrated with GMAO development and will support the design and concept development of future NASA space missions. The work will focus on ingestion of NASA and other high-altitude past and current observations describing both neutral and ionospheric properties that will require development of new observation operators for previously unused data types. The successful candidate will work in an exciting environment that crosses between neutral atmosphere physics to electrodynamic interactions.
Required Qualifications:
- PhD in Atmospheric Science or Data Assimilation
- Demonstrated ability to code in Python and other environments
- Experience running complex systems in high-performance computing systems
- Experience using upper atmospheric observations and (ideally) knowledge of the Joint Effort for Data assimilation Integration (JEDI) data assimilation tools
The successful candidate will join the GESTAR II Consortium, which supports over 140 researchers based primarily at NASA Goddard Space Flight Center. GESTAR II researchers work to create extensive opportunities for breakthroughs in earth and atmospheric science research, carrying out observational, experimental and theoretical research in support of NASA strategic Earth Science mission objectives.
