Job Description

This position is within the Global Modeling and Assimilation Office (GMAO) and will focus on thermal infrared radiance assimilation within the Goddard Earth Observing System (GEOS) data assimilation system (DAS).  A key objective of this work is to extend the use of hyperspectral radiance measurements in parts of the thermal infrared spectrum that are presently underutilized in the GEOS DAS.  The work involves development of improved radiation transfer codes and methodologies to effectively assimilate these data. 

Essential Duties/Responsibilities:

  • Develop and refine assimilation methodologies to constrain ozone using hyperspectral radiances in the 9.6 µm absorption continuum; quantify the impact of these observations alongside others used in GEOS DAS.
  • Improve the representation of radiation transfer in the shortwave infrared (4 micron) region of the electromagnetic spectrum, to extract additional information for temperature and carbon dioxide from infrared radiances.
  • Contribute to the development of new mission concepts that exploit the potential benefits of constellations of hyperspectral sounders and imagers.
  • Document the work through peer-reviewed literature.
  • Present the work at both domestic and international meetings and workshops.
  • Other job related duties as assigned

Required Qualifications:


 Ph.D. in an earth science discipline, mathematics, physics, or a related field


  • 5-10 years’ of experience in satellite remote sensing, retrieval and inversion methods, radiative transfer, and/or data assimilation.
  • Experience working with satellite data in the context of atmosphere/earth system modeling and assimilation systems.
  • 10+ publications in peer-reviewed literature.


 Knowledge, Skills & Abilities:  

  • Profound knowledge of Fortran and UNIX scripting language in a high-end computing environment
  • Experience with global data assimilation systems and global models.
  • Experience with radiative transfer codes.


  • Communicate effectively by speaking, listening and write in a clear, thorough and timely manner using appropriate and effective communication tools and techniques; communicate with a broad range of scientists and engineers in a high-pressure, results-oriented context.
  • Speak effectively before groups of customers or employees of organization.
  • Work cooperatively and effectively with others in a research environment to set goals, resolve problems and make decisions that enhance team effectiveness.
  • Establish priorities and make effective decisions daily to promote the advancement of science.
  • Solve Problems: Assess problem situations to identify causes, gather and process relevant information, generate possible solutions and make recommendations and/or resolve the problem.


Working Conditions:

Work will be performed in an office or computer lab environment.  While performing the duties of this job, the employee is frequently required to stand; walk; sit; talk or hear.  Keyboarding for large time spans each day may be a significant part of this position.
