Forwarded from CLIMLIST... 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; email@example.com <mailto:firstname.lastname@example.org>) 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; email@example.com <mailto:firstname.lastname@example.org>) 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.
