Job Description:

I.M. Systems GroupLocation: US-MD-College ParkJob ID: 2021-1254Category: ScientificOverviewI.M. Systems Group, Inc. (IMSG) is seeking a candidate to support the Environmental Modeling Center (EMC) of the National Centers for Environmental Prediction (NCEP) in carrying out research, development, and operational transition work related to data assimilation for future operational applications of the Unified Forecast System (UFS). The candidate's work will involve the development, execution, testing, and evaluation of the assimilation of Global Navigation Satellite System (GNSS) Radio Occultation (RO) observations for use in operational environmental prediction capabilities at NCEP. The work location is at the NOAA Center for Weather and Climate Prediction (NCWCP) in College Park, MD.ResponsibilitiesThe candidate will perform the job duties in a high-quality, independent, and collaborative way, assisting with developing and applying innovative methods for the primary work areas described below. The candidate will work with EMC 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 development, evaluation, and implementation of assimilation of government and commercial GNSS-RO observations into NCEP numerical modeling applications. Future assimilation related developments will leverage and contribute to the Joint Center for Satellite Data Assimilation, including the Joint Effort for Data assimilation Integration (JEDI) project. The successful candidate will work in the following areas:Provide support for currently assimilated GNSS-RO observations for operational application at NCEP.Develop new or enhance existing techniques for the improved assimilation of GNSS-based dataPrepare, design, and advance components to enable the assimilation of data for future or newly launched missionsDesign, setup, and execute impact assessment and pre-implementation testing to facilitate possible transition to operationsImprove upon quality control, bias correction, and/or observation error specification to enhance the assimilation of GNSS-RO dataDevelop techniques to improve the use of GNSS-RO data in the lower troposphere QualificationsA Master's Degree or higher in atmospheric sciences or meteorology, mathematics, or related physical science with at least 2 years of experience in forecast and analysis systems.Demonstrated knowledge, skills, and abilities in at least five of the following areas:Expert knowledge of data assimilation with focus on GNSS-RO assimilation for numerical weather prediction. Familiarity with variational data assimilation.Advanced knowledge of the physical and mathematical basis of geophysical modeling (atmospheric and/or environmental) and experience running advanced numerical weather prediction (NWP) modelsExperience in model development in various infrastructures like the Earth System Modeling Framework (ESMF) and NOAA Environmental Modeling System (NEMS)Advanced 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 languagesExperience in working with HPC platforms (MPI, OpenMP, Slurm, LSF, etc.)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.Ability to work independently and in a team environment on complex problems.Good oral and written communication skills in EnglishDemonstrated skill in performing tasks requiring organization and attention to detail. Candidates must be a U.S. Citizen or Green Card Holder to qualify and must live in US for 3-5 years prior to application. (please indicate in your cover letter).
