[ES_JOBS_NET] Research Scientist position in atmospheric chemistry and dynamics: ozone mapping

[Halley Thompson]

The Goddard Earth Sciences Technology and Research II (GESTAR II)
<https://gestar2.umbc.edu/> consortium at NASA’s Goddard Space Flight
Center (GSFC) <https://www.nasa.gov/goddard> invites applications for a
research position in the Atmospheric Chemistry and Dynamics Laboratory
(Code 614) <https://science.gsfc.nasa.gov/earth/acd/> at NASA Goddard Space
Flight Center. The lab advances understanding of changes in the Earth’s
radiation balance, air quality, and the ozone layer that result from
changes in atmospheric composition. Using a combination of satellite data,
atmospheric models, and in situ observations, the laboratory strives to
understand: the factors that control stratospheric ozone and trace gasses
that influence ozone, the natural processes and human activity that impact
the composition of Earth’s troposphere, and the impact of climate change on
future concentrations of stratospheric ozone and tropospheric gasses.

The successful candidate will use radiative transfer models and remote
sensing tools to study tropospheric ozone and aerosols. This position is
best suited for a candidate with experience in big data and will focus on
combining measurements from multiple sensors to develop new retrieval
algorithms to derive tropospheric ozone.

The successful candidate will join the GESTAR II Consortium which supports
over 120 researchers based primarily at NASA Goddard Space Flight Center
(GSFC). GESTAR II researchers work to create extensive opportunities for
breakthroughs in earth and atmospheric science research, carrying out
observational, experimental and theoretical research in support of NASA
strategic Earth Science mission objectives.

Goddard’s Earth Science Division is home to about 200 civil servants and
over 1200 collaborating researchers and support personnel dedicated to
studying the Earth as an integrated system that includes the atmosphere,
oceans, biosphere, cryosphere, and geosphere. The Division operates as a
component of the Sciences and Exploration Directorate that collaborate on
interdisciplinary research with the Astrophysics Science, Heliophysics
Science, and Solar System Exploration Divisions.

The researcher will focus on:

Suomi NPP Ozone Mapping and Profiler Suite (OMPS), launched in 2011,
comprises of three complementary sensors – Limb Profiler (LP), Nadir
Profiler (NP) and Nadir Mapper (NM) – that scan the same region of the
atmosphere from Earth’s surface to the mesosphere within minutes enabling
retrievals of total columns and vertical ozone profiles. Ozone observations
with OMPS instruments will be extended to mid-century with a series of JPSS
missions. This opportunity is for a candidate interested in remote sensing
and data analysis. This work will include evaluation of ozone total columns
and vertical profiles retrieved from limb and nadir OMPS sensors and
comparisons with independent ground-based and satellite measurements and
model simulations. This validation will be aimed to assess the accuracy,
precision and stability of OMPS ozone products. The acccurate error budget
is required for continuation of the historical ozone data records and for
investigation of long-term ozone changes.

Required knowledge and skills:

A successful candidate should have a Master or PhD degree in one of the
following STEM fields Computer Science, Mathematics, Physics, or
Meteorology and have advanced programming skills working with big data
(e.g. Python, IDL, Fortran). Experience in applying various statistical
methods for data analysis (e.g. regression analysis, principal component
analysis, machine learning methods) and basic knowledge of remote sensing
are highly desirable. A successful candidate is expected to have excellent
verbal and written communication skills, as demonstrated by peer-reviewed
publications and oral presentations made at science conferences and
workshops. A candidate should be capable of working both independently and
within a dynamic project science team.

How to apply:

Candidates should provide a cover letter, three page statement of research
interests and CV (including publication list). Short-listed candidates will
be asked to supply three letters of reference at a later date. All
materials and inquiries should be sent by email Subject line: Task 143:
Research Scientist position to: Halley Thompson halleyt at umbc.edu.

Salary and benefits are competitive, commensurate with experience and
qualifications. The GESTAR II consortium and NASA/GSFC are committed to
building a diverse research community and encourages applications from
women, racial and ethnic minorities, individuals with disabilities and
veterans. All GESTAR II institutions are Affirmative Action, Equal
Opportunity Employers.

This posting will remain open until 10/21/2022. The nominal starting date
is late November, but alternate dates are possible depending on
availability.

This position is a one-year contract, renewable depending upon performance
and funding availability.
