Duties

Help
  • Develop fast and accurate radiative transfer models in far-InfraRed (IR), mid-IR, near-IR, visible, and Ultraviolet (UV) spectral region for a wide range of satellite sensors relevant to NASA missions.
  • Develop a unified retrieval algorithm that uses a consistent radiative transfer model to perform climate quality data analysis of a wide range of NASA satellite data.
  • Conduct sensor performance studies for future NASA satellite sensors including CubeSat by using instrument design specifications, radiative transfer models, and inversion algorithms.
  • Utilizes the radiative transfer model (RTM) to perform end-to-end performance simulations for new sensor systems, satellite data inversions, and geophysical parameter retrievals.
  • Duties described above are at the full-performance level. Duties assigned at a lower grade level will be of more limited scope, performed with less independence and limited complexity; duties will be commensurate with the grade of selected employee.

Vacant research positions may be filled at one of several grade levels depending upon the scientific impact of the person selected. A review may be required to determine the appropriate grade level of the position and supplemental materials may be required from the selectee. Please keep this in mind when indicating the lowest grade you will accept.

Your resume must include a clear and detailed narrative description, in your own words, of how you meet the required specialized experience. Experience statements copied from a position description, vacancy announcement or other reference material constitutes plagiarism and may result in disqualification and losing consideration for the job.

Please spell out all acronyms.

Education

In order to qualify for this position you must meet Basic Education Requirement.

Applicants must have successfully completed an undergraduate or graduate degree with a major in either a) engineering from a college or university that has ABET accredited engineering programs or b) Physical Science, Mathematics, Life Science, Computer Science*, Other fields of science.

Required college majors for applicants qualifying on the basis of undergraduate or graduate education only:
Any appropriate field of engineering, physical or computer science or mathematics. Study must include or be supplemented by six semester hours or the equivalent in appropriate life or other natural science courses, and include or be supplemented by at least two courses which would provide knowledge of subjects appropriate to the vacancy being filled.

*Note: Curriculum must include 30 semester hours of course work in a combination of mathematics, statistics and computer science. Of the 30 semester hours, 15 must be in any combination of statistics and mathematics which includes differential and integral calculus.

Degrees in engineering technology are not considered to be qualifying for this position.

When there is a positive education requirement, or you are using education to qualify as a substitution for experience, official transcripts may be required at the time of selection to verify that you meet the educational requirement or substitution.

All degree(s) must have been awarded from colleges or universities that are accredited by recognized accrediting organizations. For a list of schools that meet this criteria, go to http://ope.ed.gov/accreditation/. Engineering degrees must have been awarded from a college or university school of engineering with at least one curriculum accredited by the Engineering Accreditation Commission (EAC) of the Accreditation Board for Engineering and Technology (ABET). To find out if a degree meets this requirement, go to http://www.abet.org.
