USRA is an independent, nonprofit research corporation where the combined efforts of in-house talent and university-based expertise merge to advance space science and technology. USRA works across disciplines including biomedicine, planetary science, astrophysics, and engineering and integrates those competencies into applications ranging from fundamental research to facility management and operations. USRA engages the creativity and authoritative expertise of the research community to develop and deliver sophisticated, forward-looking solutions to Federal agencies and other customers - on schedule and within budget.
USRA seeks a scientist for a full-time exempt position in the Greenbelt, MD area . The postdoctoral scientist will work on the Goddard Earth Science Technology and Research (GESTAR) program.
Duties and Responsibilities
Assimilation of atmospheric CO2 observations into the GEOS-5 data assimilation system.
Developments to GEOS-5, especially to develop and implement background error models based on ensemble techniques and bias correction algorithms.
Participation in research studies aimed at evaluating observations from AIRS, GOSAT, and OCO-2 data using GEOS-5, and applying these to understanding of the carbon cycle.
Ph.D. in the physical sciences, focusing on Earth Science is required.
Research-based knowledge (demonstrated by publications) of the carbon cycle, constituent data assimilation, global transport modeling and/or the use of space-based radiance observations is essential.
Knowledge of FORTRAN programming and data analysis tools (e.g., IDL, GrADS) is important, as is the ability to use modern programming architecture (e.g., ESMF) on multi-processor computational platforms.
