To qualify for the GS-13:

Specialized experience equivalent to the next lower grade (GS-12) is experience such as:
-Analyzing, interpreting, and modeling in-situ measurements focused on improving understanding of the vertical distribution and changes of atmospheric ozone, published the results in the peer-reviewed literature.
- Diagnosing the relative contributions of transport and chemical effects in causing variations and changes of the vertical distribution of atmospheric ozone.
- Performing fundamental studies of atmospheric composition and transport and interpretation of measurements involving multiple data sources (e.g., model projections, balloon, ground based, meteorological data, and satellite data, published the results in the peer-reviewed literature).
- Supporting the development, operation and calibration of ozone measuring instrumentation, particularly balloon-borne in-situ ozone.

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.

Education

Basic Education Requirement: A bachelor's degree from an accredited college or university with major study in Aeronautical Engineering, Aeronautics, Aerospace Engineering, Architecture, Astronautical Engineering, Astronautics, Astronomy, Astrophysics, Biomedical Engineering, Ceramic Engineering, Ceramics, Chemical Engineering, Chemistry, Civil Engineering, Computer Engineering, Computer Science*, Life Science, Earth and Planetary Science, Electrical Engineering, Electronics Engineering, Geology, Geophysics, Industrial Engineering, Materials Engineering, Materials Science, Mathematics (Pure or Applied), Applied Mechanics, Engineering Mechanics, Mechanical Engineering, Metallurgical Engineering, Metallurgy, Meteorology, Nuclear Engineering, Nuclear Engineering Physics, Oceanography, Optical Engineering, Physics, Applied Physics, Engineering Physics, Space Science, Structural Engineering, Welding Engineering or other appropriate physical science or engineering field. Degrees in engineering technology are not considered to be qualifying for this position.

*Note: Curriculum must include 30 semester hours of course work in a combination of mathematics, statistics and computer science that provided in-depth knowledge of the following: (1) theoretical foundations and practical applications of computer science, including digital computer system architecture and system software organization, the representation and transformation of information structures and the theoretical models for such representations and transformations; and (2) essential mathematical and statistical techniques. Of the 30 semester hours, 15 must be in any combination of statistics and mathematics which includes differential and integral calculus

Science and other related degrees 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/.

U.S. 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.

Foreign Engineering degrees must be recognized by a Mutual Recognition Agreement (MRA), often known as accords These are non-governmental agreements among organizations that accredit academic degree programs. MRAs recognize the substantial equivalence of mature accreditation systems and programs accredited by signatory organizations within their jurisdictions. For a listing of Signatories, please visit, https://www.abet.org/global-presence/mutual-recognition-agreements/is-your-program-recognized/.

If you are using education completed in foreign colleges or universities to meet the qualification requirements, you must show that the education credentials have been evaluated by a private organization that specializes in interpretation of foreign education programs. These education credentials must be deemed equivalent to that gained in an accredited U.S. education program; or full credit has been given for the courses at a U.S. accredited college or university. For further information, visit: https://www2.ed.gov/about/offices/list/ous/international/usnei/us/edlite-visitus-forrecog.html.

All degrees must have been received in the year of, or any year subsequent to the original date of accreditation.

Official transcripts will be required at the time of selection to verify that you meet the educational requirement or substitution.
