Two Post-Doctoral Positions

Available at the Center for Western Weather and Water Extremes (CW3E)

Part of UC San Diego’s Scripps Institution of Oceanography

Location: La Jolla, CA.
Deadline: Positions are available immediately.  Applications will be
considered until positions are filled.  Preference will be given to
applications received by 31 July 2016

Number of new positions available: 2

The Center for Western Weather and Water Extremes, (CW3E; cw3e.ucsd.edu
<http://cw3e.ucsd.edu>) is a research and applications center
established in 2013 at Scripps Institution of Oceanography by its
Director, Dr. F. Martin Ralph.  CW3E focuses on the physical
understanding, observations, weather predictions, seasonal outlooks and
climate projections of extreme weather and water events to support
effective policies and practices to improve resilience in the Western
U.S.  Funding for this set of Postdoctoral positions is in place from
several federal, state and local agencies, with a major emphasis on the
unique science and applications needs associated with water supply and
flood risk in the Western United States.  CW3E carries out its goals
with a diverse network of research and operational partners at more than
ten other institutions across the U.S.  Individuals will be joining a
group of several existing Postdoctoral scholars and graduate students,
and a number of experienced faculty, researchers and staff at Scripps
who are involved with CW3E.

Per normal Postdoctoral appointment policies, all positions are
envisioned as being initially for 1-year, with extension possible
contingent upon performance and availability of funding. The University
of California, San Diego is an AA/EOE.

Interested individuals are encouraged to submit their resumes and a
1-page statement of relevant personal interests, goals, range of
potential start dates and references.These should be sent to the person
listed below as the “position coordinator” for the position you are
interested in.

Applicants should have 0-2 years of Postdoctoral experience, or be
nearing completion of their Ph.D. (estimated within 3 months), and be
self-motivated and hard-working.Good written and verbal communication
skills, including the ability to produce scientific publications and
presentations and meet project milestones are required.Strong analytical
backgrounds with a Ph.D. in atmospheric science, meteorology,
atmospheric chemistry, climate science, hydrology or environmental
engineering is preferred.Programming experience working in a Unix
environment with experience in scripting languages such as Python, Perl,
R and Matlab along with true programming language experience in C and
Fortran is highly desired. Successful applicants should be comfortable
independently working with large code libraries and producing novel
visualizations.Experience with GIS-based mapping tools is also desired.

Position 1: Data Assimilation (CW3E position coordinator – Dr.  Bruce
Cornuelle; bdc@ucsd.edu <mailto:bdc@ucsd.edu>)

CW3E seeks a Postdoctoral researcher to work with local experts to use
data assimilation tools with the Weather Research and Forecasting (WRF)
regional weather model to produce and analyze hindcasts and forecasts of
Atmospheric River (AR) precipitation along the US West Coast.  The goals
are to understand and improve the model physics and parameterizations,
improve forecasts, explore sensitivities, quantify uncertainty, identify
the impacts of observations, and optimize sampling.

CW3E intends to unify model evaluation, improvement, and delayed-mode
and real time data assimilation and forecasting, using the assimilation
to provide information on model biases, initialization shortcomings,
error sources and growth, and the limits of predictability. The project
will use two advanced methods already implemented in WRF: the Data
Assimilation Research Testbed (DART), an open-source community facility,
and at least the adjoint component of WRF-4DVAR. Implementation and
testing of these data assimilation methods will focus on monitoring and
predicting key aspects of ARs, including the role of mesoscale frontal
waves.Assimilation of ground-based measurements from the Western US
network of wind profiling radars, snow-level radars and GPS-met
measurements will be a priority.The project will also evaluate the
efficacy of offshore airborne reconnaissance methods using manned and
unmanned aircraft. The ideal candidate will have experience with modern
data assimilation methods and strong computing skills (including Fortran
and Matlab). The candidate should have demonstrated ability to
independently produce new algorithms and successfully integrate them
with existing large code libraries. Experience with WRF is desired but
not required.

Position 4: Forward chemical transport model-based methods for
estimating GHG emissions in Southern California(CW3E position
coordinator – Dr.  Andrew Martin; mc@ucsd.edu <mailto:mc@ucsd.edu>)

CW3E seeks a Postdoctoral researcher to design, implement and validate a
high-resolution forward chemical transport modeling system that can be
fully integrated with inverse emissions estimates and directly compared
to weather observations and in-situ trace gas measurements. Work will be
conducted in collaboration with numerical weather prediction and trace
atmospheric measurements experts at Scripps Institution of Oceanography,
NASA Jet Propulsion Laboratory, and the National Institute for Standards
and Technology.

The selected candidate will collaborate with CW3E and other Scripps
researchers on projects focusing on forward trace gas modeling with the
WRF/CHEM regional chemical transport model, gas measurement network
design and analysis, and forward model meteorology and gas concentration
validation. Under the direction of project personnel, the successful
candidate will develop a high-resolution WRF/CHEM configuration that
accurately models trace gas accumulation, chemical change, transport,
and removal (the forward modeling system), will analyze the suitability
of trace gas measurements and the forward modeling system under
challenging meteorological scenarios and will validate chemical and
meteorological forecasts using direct measurements. The candidate will
have the opportunity to participate in inverse modeling studies for
source quantification, for which inverse modeling experience may be
valuable.The successful candidate will also have the opportunity to
present results at major conferences and will be expected to publish
results in a peer-reviewed journal as first author.
