The University Corporation for Atmospheric Research (UCAR) Visiting Scientist Programs (VSP), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), Environmental Protection Agency (EPA), and the Office of Air Quality Modeling (AQ) are seeking applications for the NOAA/EPA postdoctoral fellowship program in regional/urban air quality modeling. UCAR manages this NOAA/EPA-sponsored program, which pairs recently graduated postdoctorates with host scientists at EPAs National Exposure Research Laboratory (NERL) in Research Triangle Park, North Carolina.

Postdoctoral positions are available in the Atmospheric Sciences Modeling Division of NOAAs Air Resources Laboratory (ARL) working with investigators in developing and testing EPAs air quality modeling system. Opportunities exist to work on a chemical transport model, based on an advanced version of the Regional Acid Deposition Model, with the MM5 prognostic meteorological model using 4DDA as a driver. The modeling system will be migrating to the new EPA Models-3 computational framework this year.

The work will include study of the effects of dynamics and thermodynamics descriptions in meteorological models critical to air quality predictions (particularly thermodynamic descriptions, surface/PBL descriptions; cloud parameterizations; mass conservation). The work will also include improvements of numerical algorithms and predictive accuracy and diagnosis of the impact of different parameterizations within the MM5 option set or developed for MM5 on representations of physical processes critical to air quality predictions, advancements in 4DDA to improve the accuracy of critical physical variables, development of systematic sensitivity analysis methods applicable for meteorological and air quality models, analysis of coupled meteorological-chemical model sensitivity experiments, and evaluation of meteorological model predictions using episodic meteorological data from field programs.

Candidates should have a PhD in meteorology with experience in numerical meteorological modeling, but need willingness to work with MM5. Familiarity with UNIX environment (the MM5 is run on Cray C90 and T3D computers). Ability to work independently and as a contributing member of a team is necessary. Familiarity with 4DDA is desirable and massively parallel computation is a plus.

Fellows receive a fixed annual stipend. Benefits include health and dental insurance, sick and annual leave, paid holidays, mandatory participation in a retirement fund (TIAA/CREF), and life insurance. A relocation allowance is provided as well as an allowance for scientific travel and other support costs.

To apply, send:

• A cover letter stating the name of this program.
• Curriculum Vitae with a list of publications.
• Names and addresses of four professional references (applicants should request that reference letters be sent to UCAR/VSP by the application deadline).
• MS or PhD thesis abstract, including title of thesis.
• One to two page statement of experience and interests as related to goals of program.

Application deadline: 1 June 1998.
