What are the responsibilities and job description for the Physical Scientist for All-sky and All-surface Radiance Satellite Data Assimilation position at Lynker?
Lynker is looking for a Physical Scientist for All-sky and All-surface Radiance Satellite Data Assimilation 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 satellite data assimilation for operational applications of the Unified Forecast System (UFS). The candidate’s work will involve the development, execution, testing, and evaluation of innovative techniques to enhance the direct assimilation of “all-sky/all-surface” satellite radiances for use in operational environmental prediction capabilities at OMD. The Ideal Physical Scientist for All-sky and All-surface Radiance Satellite Data Assimilation, will be local to the DC Metro area, and be able to work a hybrid schedule, working 2 days per week in office out of the College Park, MD location, and working from home the remaining 3 days of the week.
The Physical Scientist for All-sky and All-surface Radiance Satellite Data Assimilation will perform the job duties in a collaborative environment, assisting developing and applying innovative methods for the primary work areas described below. The candidate will work with OMD scientists and external collaborators to develop innovative all-sky/all-surface satellite radiance data assimilation capabilities for use in applications of the UFS, with emphasis on global medium range numerical weather prediction. In particular, the candidate will utilize the Community Radiative Transfer Model (CRTM). The work will leverage and contribute to the Joint Center for Satellite Data Assimilation, including the Joint Effort for Data assimilation Integration (JEDI) project.
Duties of the Physical Scientist for All-sky and All-surface Radiance Satellite Data Assimilation will include the following
