Summary
The Chemistry and Dynamics Branch within the Science Directorate (SD), is seeking an individual to serve as a Research Physical Scientist. Responsibilities may include the following: Conducting research that utilizes both in-situ and remote-sensing observations for tropospheric and stratospheric aerosols; supports development of an in-situ measurement capability for stratospheric aerosol observations from airborne and/or balloon-based platforms, with requirements driven by applications such as satellite validation, retrieval development, and scientific investigation, and; supports the development, operation, data reduction, and validation of aerosol measurements in the upper troposphere and stratosphere from in-situ and/or on-orbit instrumentation, along with analyses and/or modeling that would allow results of different aerosol measurements to be compared or combined synergistically to derive information about aerosol physical properties that cannot be inferred from only one measurement system.
This position may be filled at either the GS-12 or GS-13 levels. You may receive a non-competitive promotion(s) to the full performance level of GS-14, when eligible and recommended by management. Identification of promotion potential in this position does not constitute a commitment or an obligation on the part of management to promote the employee. Promotion will depend upon administrative approval and the continuing need for an actual assignment and performance of higher level duties.
Deliberate attempts to falsify your resume, such as, copying portions of this job announcement into your resume, may result in you being removed from consideration for this position.
To receive consideration, you must submit a resume and answer NASA-specific questions. The NASA questions appear after you submit your resume and are transferred to the NASA web site. If you successfully apply, USAJOBS will show your application status as 'Received'. If your status is 'Application Status Not Available', you have not successfully applied. Do not rely on a USAJOBS email to confirm successful application. Only an email from NASA confirms a successful application

Duties
The scientist will perform research directed toward discovering, disseminating, and applying new or expanded knowledge of chemical, dynamic and radiative processes which regulate the spatial and temporal distributions and abundances of radiatively and chemically active tropospheric and stratospheric aerosols.
Provides specialized expertise for characterizing and improving the performance of laboratory and field-deployable instruments for measuring and characterizing the composition, concentrations, microphysical/radiative properties and spatial distributions of trace atmospheric constituents. The scientist works with technicians and engineers in calibrating, integrating and operating instruments aboard space-borne, airborne and other mobile platforms to perform detailed studies of atmospheric composition, air quality, and/or source characteristics, such as supporting development of an in-situ measurement capability for stratospheric aerosol observations from airborne platforms and balloon-based measurements. The scientist will devise/apply methods for evaluating and improving measurement performance and correcting and/or interpreting data from research-grade sensors for both in-situ and remote-sensing observations for atmospheric aerosols; devise/apply methods for correcting data sets for sampling losses/biases and for quickly evaluating instrument performance and the internal consistency between different sensors within the overall measurement suite.
Works with and/or lead tasks, for example, interpreting sub-orbital and/or satellite remote sensing measurements of the atmosphere related to regional and global change phenomena, developing and/or validating pioneering remote sensing data retrieval techniques, publishing results of such investigations. Support the development, operation, data reduction, and validation of aerosol measurements in the stratosphere and upper troposphere from in-situ and/or on-orbit instrumentation. The scientist may develop new measurement techniques and enabling hardware and software technologies for future satellite and/or suborbital missions. The scientist identifies crucial limitations in the current state-of-the-art techniques, practices, and component performance and devises innovative improvements or alternatives that can overcome or bypass current limitations.
Leads or makes major contributions to scientific studies of atmospheric composition, including aerosol vertical, spatial, and temporal variability. Collaborates with internal and external investigators employing analysis methods, models and remote sensing information to derive regional-to-global distributions and properties of atmospheric trace constituents. Develops unique, innovative analysis and/or modeling techniques for investigating the dynamic interactions between and with trace atmospheric species, including radiatively important trace gases and aerosols. Contributes to the development and/or evaluation of algorithms for deriving properties from remotely sensed measurements.
