Support Scientist for JEDI Data Assimilation Transition to Operations

Overview Lynker is looking for a Support Scientist for JEDI Data Assimilation Transition to Operations to support the Office of Modeling and Development (OMD) of the National Weather Service (NWS) in carrying out research, development, and operational transition work related to atmospheric data assimilation for operational applications of the Unified Forecast System (UFS). The candidate’s work will involve the development, execution, testing, and evaluation of several components of the atmospheric data assimilation system in the context of numerical weather prediction. Preference will be given to candidates with experience in Satellite Radiance Data Assimilation. Responsibilities The candidate will perform the job duties in a collaborative environment, assisting developing and applying innovative methods for the primary work areas described below. The candidate willwork with OMD scientists and external collaborators to develop and test atmospheric data assimilation components for use in the UFS. In particular, the candidate will focus on the evaluation of the components of the Joint Effort for Data assimilation Integration (JEDI) project for use in global numerical weather prediction applications at NCEP. Duties of the Support Scientist for JEDI Data Assimilation Transition to Operations will include the following: Assist in development, evaluation, testing, and transition of JEDI-based developments for replacement of current atmospheric assimilation infrastructure (GSI-based). Transition observation modeling, quality control and bias correction to JEDI. Develop and support atmospheric model interface within the JEDI infrastructure. Test and evaluate JEDI-based algorithm developments for use in operational NWP applications. Assist in coordination of JEDI-related development activities from other OMD developers. Utilize JEDI infrastructure to explore data assimilation research activities relevant to future transition-to-operations of operationally relevant data assimilation research. Other duties as assigned. Qualifications The Support Scientist for JEDI Data Assimilation Transition to Operations selected should have the following: Knowledge of data assimilation techniques (variational-based and/or ensemble methods). Knowledge of the physical and mathematical basis of geophysical modeling (atmospheric and/or environmental) and experience running advanced numerical weather prediction (NWP) models. Knowledge and experience of modern programming languages such as object-oriented FORTRAN, Python, and/or C++. Experience working in a UNIX environment with advanced scripting languages Good oral and written communication skills in English. The Ideal Support Scientist for JEDI Data Assimilation Transition to Operations will have the following: Advanced knowledge of satellite radiance data assimilation. Knowledge of radiative transfer and experience with radiative transfer modeling for data assimilation, such as the Community Radiative Transfer Model (CRTM) or Radiative Transfer for TOVS (RTTOV). Experience in running numerical models on High Performing Computer (HPC) platforms using MPI, OpenMP, Slurm, LSF, etc. Experience with coupled earth system models. Knowledge of modern software engineering practices (requirements gathering, design, prototyping, version control, integration, testing, and documentation). Experience in model testing and evaluation and/or knowledge of verification principles. Experience in model development in various infrastructures like the Earth System Modeling Framework (ESMF) and NOAA Environmental Modeling System (NEMS) About Lynker Lynker is a growing, employee owned business, specializing in professional, scientific and technical services.
