<p class="MsoNormal"><span style="color:black">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">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.<o:p></o:p></span></p>
