The incumbent of this position will work to integrate existing soil moisture data assimilation system with GMAO’s coupled subseasonal-to-seasonal (S2S) forecasting system, resulting in a fully coupled land-atmosphere-ocean S2S prediction framework. This work will involve both the direct insertion of soil moisture estimates from the Soil Moisture Active Passive (SMAP) Level-4 product into the GEOS S2S framework, as well as directly coupling the soil moisture data assimilation system with the GEOS S2S system to ensure that the atmosphere is informed by land characteristics during forecast initiation. This work will also include the assessment of S2S forecast performance with the new soil moisture data assimilation integration, particularly over High Mountain Asia, Himalayan forelands and India. As part of their duties, the postdoctoral researcher will actively engage with the GMAO Land Processes Group, GMAO S2S Group, and NASA’s Understanding High Mountain Asia Research Team. This is a 2-year appointment. Essential Duties/Responsibilities: – Work towards developing a fully coupled land-atmosphere-ocean S2S prediction framework – Assimilate soil moisture estimates from the SMAP L4 product into the GEOS S2S framework – Assessment of S2S forecast performance at regional to global scales – Use of MERRA-2, GEOS modeling system and the GMAO S2S framework to advance GMAO data assimilation capabilities – Actively engage with the GMAO Land Processes Group, GMAO S2S Group, and NASA’s Understanding High Mountain Asia Research Team – Engage the academic community, both national and international, in research work through research collaborations, visits, invited guests, workshops, conferences, etc. – Develop an awareness of NASA’s mission needs and address them to the best of ability. – Complete all trainings as required. – Other job-related duties as assigned Required Qualifications: Education: – PhD in Hydrology, Atmospheric Sciences or Earth Sciences related field. Experience: – 0-2 years of postdoctoral experience Knowledge, Skills & Abilities: – Strong background in land modeling and data assimilation – Experience in interpreting meteorological results, particularly in the construct of hydrological and land data assimilation systems – Experience in running integrated modeling and data assimilation systems – Experience with soil moisture datasets, as available from satellite missions like SMAP or ESA SMOS – Knowledge of structured programming languages as well as software packages for data processing and visualization – Proficiency in Unix environment; – Ability to work with large data files in hdf or netcdf format. – Strong publication and presentation skills Technology: – Excellent quantitative, computational, and programming skills (including Fortran, MATLAB, Python) – Knowledge or ability to learn advanced computing techniques in an ESMF environment, with GIThub code management, and OpenMP/MPI coding techniques is essential. Attributes: – Strong analytical and problem-solving background. – Strong verbal and written communication skills. – Ability to think critically and innovatively with an interest in interdisciplinary studies. – Willingness to learn and improve. – Strong team player. – Ability to contribute to team-focused developments of large, complex data assimilation systems Additional List of Requirements: – Meet regularly with the GSFC Sponsor and other team members to plan experiments and report results. – Demonstrate ability to work independently towards science research goals. Document science studies through internal presentations to peers and through written manuscripts, for GMAO reports or peer-reviewed publications, as appropriate. – Commit code developments to GMAO’s Git repositories and assist colleagues in using these code developments in evolving GMAO systems. – Demonstrate commitment to teamwork and collaboration across the GMAO. – Contribute to the intellectual growth of colleagues by engaging in scientific and technical discussions, making presentations at internal meetings, etc. – Follow all NASA rules and regulations regarding access to center, use of IT equipment, and building access, as defined through the Satern training opportunities.
