Research Scientist position in GEOS model development to understand High Mountain Asia forecast models

The Goddard Earth Sciences Technology and Research II (GESTAR II) consortium at NASA's Goddard Space Flight Center (GSFC) invites applications for a research position in the Global Modeling and Assimilation Office (GMAO) (Code 610.1) at GSFC. The office works to maximize the impact of satellite observations in climate, weather and atmospheric composition prediction using comprehensive global models and data assimilation. To achieve this goal, the GMAO develops models and assimilation systems, generates products to support NASA instrument teams and the NASA Earth science program, and undertakes scientific research to inform system development pathways.GMAO's long-term goal is an integrated Earth system model and assimilation system that treats the individual components in a more coupled and interactive manner.

The successful candidate will work to understand how model initial conditions, particularly snow cover, and model characteristics impact GEOS-S2S (Goddard Earth Observing System Subseasonal to Seasonal Prediction System) forecast performance over High Mountain Asia, the Himalayan forelands and India.

The researcher will build on previous work to integrate MODIS snow cover fraction assimilation within GEOS Land Data Assimilation System (GEOSldas). They will perform a suite of experiments to examine the impact of improved snow cover initial conditions on seasonal prediction of hydrometeorological variables within the GEOS-S2S system. In addition to model development and validation, responsibilities include leading or contributing to the publication of peer-reviewed scientific articles and active participation in GMAO Land Processes Group, GMAO S2S Group, and NASA's Understanding High Mountain Asia Research Team.

The researcher will join the GESTAR II Consortium which supports over 120 researchers based primarily at NASA Goddard Space Flight Center (GSFC). 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.

Goddard's Earth Science Division is home to about 200 civil servants and over 1200 collaborating researchers and support personnel dedicated to studying the Earth as an integrated system that includes the atmosphere, oceans, biosphere, cryosphere, and geosphere. The Division operates as a component of the Sciences and Exploration Directorate that collaborate on interdisciplinary research with the Astrophysics Science, Heliophysics Science, and Solar System Exploration Divisions.

Required knowledge and skills:

  • PhD in Hydrology, Atmospheric Sciences or Earth Sciences related fields, with direct experience with data assimilation systems.
  • A demonstrated ability to contribute to team-focused developments of large, complex data assimilation systems.
  • Excellent quantitative, computational, and programming skills (including Fortran, MATLAB or Python, & git or other software version control).
  • A strong ability to think critically and actively engage with a wide range of researchers.
  • Strong written and verbal communication skills.

This position is envisioned as a postdoctoral researcher position, but the title is flexible given candidate qualifications.

How to apply:

Candidates should provide a cover letter, three page statement of research interests and CV (including publication list). Short-listed candidates will be asked to supply three letters of reference at a later date. All materials and inquiries should be sent by email Subject line: Task 144: Research Scientist position to: Halley Thompson

Salary and benefits are competitive, commensurate with experience and qualifications. The GESTAR II consortium and NASA/GSFC are committed to building a diverse research community and encourages applications from women, racial and ethnic minorities, individuals with disabilities and veterans. All GESTAR II institutions are Affirmative Action, Equal Opportunity Employers.

This posting will remain open until 8/12/22. The nominal starting date is early fall, but alternate dates are possible depending on availability.

This position is a one-year contract, renewable depending upon performance and funding availability.
