TITLE: Physicist, IS - 1310 Grade 12, $75,222.00 - $97,787.00 / ANNUALLY
TYPE OF POSITION: Trust Fund (non-Federal) Indefinite
LOCATION: Cambridge, MA
AREA OF CONSIDERATION: This position is open to all qualified candidates.

This is the position of Physicist in the Atomic and Molecular Physics Division of the Smithsonian Astrophysical Observatory. The employee will perform research on atmospheric composition measurements from Earth satellites. The employee will be part of a research group working to design, develop and implement software for atmospheric measurements and to perform scientific research using such measurements. The software will include advanced algorithms for production of data products for gases, aerosols, and clouds. Research includes Earth science process studies using satellite measurements, including studies of pollution sources, sinks, and transformations.


Duties of the position may include but are not limited to:

1. Defining scientific and system requirements to develop and evaluate advanced scientific and numerical algorithms. This will involve implementing retrieval algorithms for satellite-based nadir remote sensing of tropospheric constituents. Obtain necessary data to verify requirements and test software.

2. Assisting other scientists and/or programmers in developing programs for and in use of the satellite measurements.

3. Performing scientific studies involving satellite measurements, global chemical transport modeling, radiative transfer, tropospheric chemistry, and spectroscopy.

4. Preparing refereed publications and present talks at professional meetings.


All applicants must meet these Basic Requirements: A. Degree: physics; or related degree that included at least 24 semester hours in physics; OR B. Combination of education and experience -- courses equivalent to a major in physics totaling at least 24 semester hours, plus appropriate experience or additional education. In either A or B above, the courses must have included a fundamental course in general physics and, in addition, courses in any two of the following: electricity and magnetism, heat, light, mechanics, modern physics, and sound.

In addition to Basic Requirements above, you must have: a) One year of specialized experience that is equivalent in difficulty and responsibility to grade 11 level work in the Federal government. The experience would have included defining scientific and system requirements to develop and evaluate advanced scientific and numerical algorithms; performing scientific studies involving satellite measurements; preparing publications and presenting talks at professional meetings.


Education for Grade 12: Ph.D. or equivalent doctoral degree.


Combinations of successfully completed graduate level education and specialized experience may be used to meet total experience requirements.

Qualification requirements must be met within 30 days of the job opportunity announcement closing date. For information on qualification requirements, see Qualification Standards Handbook for General Schedule Positions viewable on the web at
