[Minghua Zheng]

Hello,

The Center for Western Weather and Water Extremes <https://cw3e.ucsd.edu/>
at
Scripps Institution of Oceanography, University of California San Diego, is
seeking an atmospheric data assimilation postdoc. Applications accepted
initially
through 5 April but will remain open until filled. Please see the job
description below for more information and don't hesitate to reach out to
me via email (mzheng at ucsd.edu) if you have any questions at all. Thanks for
your attention!

Regards,

*Atmospheric Data Assimilation Postdoctoral Position*

*Center for Western Weather and Water Extremes (CW3E)*

*Scripps **Institution of Oceanography, University of California San Diego*

*Job Location*: La Jolla, California

*To Apply*: Send CV, cover letter, and three references to Dr. Minghua
Zheng (mzheng at ucsd.edu) and Dr. Luca Delle Monache (ldellemonache at ucsd.edu).

*Open date: *The position is available immediately*.*

*Final date: *Friday, April 5, 2025, at 11:59pm (Pacific Time)

*Applications will continue to be accepted until this date, but those
received after the review date will only be considered if the position has
not yet been filled. *

*About Us:* The Center for Western Weather and Water Extremes (CW3E;
https://cw3e.ucsd.edu/) is a research and applications center established
in 2014 at the Scripps Institution of Oceanography by its Director, Dr. F.
Martin Ralph. CW3E focuses on the physical understanding, observations, and
predictions of extreme weather and water events to support effective
policies and practices to improve resilience in the Western U.S. CW3E
carries out its goals with a diverse network of research and operational
partners at several other institutions across the U.S. and internationally.
A key activity of the CW3E will be to develop methods and systems to aid
future reservoir operations for flood control, water supply, and
ecosystems. The new hire will join a collaborative group of postdoctoral
scholars and experienced researchers, faculty, and staff at CW3E and
Scripps.

*Salary Range*: A reasonable salary range estimate for this position is
$68,500-72,707

*Position Details:* CW3E seeks a postdoctoral researcher to help develop
the data assimilation system for the Model for Prediction Across Scales
(MPAS) leveraging the Joint Effort for Data Assimilation Integration (JEDI)
framework. We specifically aim to use this system to evaluate the impact of
Atmospheric River Reconnaissance data across various temporal scales,
including short-range, medium-range, and extended-range assessments.
Furthermore, the development of MPAS-JEDI tailored to northeast Pacific
extreme events will allow us to better understand the dynamics and
predictability of landfalling atmospheric rivers and their cascading
impacts.

The successful candidate will work with the team to implement the MPAS-JEDI
system on HPCs and apply the system to atmospheric river case studies. The
candidate will work closely with the team to understand how field
observations such as dropsondes and ocean drifters improve initial
conditions over the North Pacific Ocean and subsequent forecasts of
landfalling atmospheric river and other high-impact events in multiple
downstream regions. Understanding the potential observation impact in
Week-2 is a key focus of the work being carried out at CW3E as well as the
collaborative effort between CW3E/Scripps and several operational centers.

Applicants should be self-motivated and have a Ph.D. degree (by their
hiring date) in Atmospheric Science, Physical Oceanography, Climate
Science, or other relevant disciplines. Good written and verbal
communication skills are required, including the ability to produce
scientific publications and presentations and meet project milestones.
Experience with high-performance computing (HPC) platforms is essential,
along with proficiency in programming languages such as Fortran and C/C++,
as well as scripting languages like Python, Matlab, or R. Familiarity with
data assimilation systems such as JEDI, WRFDA, GSI, or DART, and numerical
models like WRF, MPAS, or GFS is also required. Applicants should be
comfortable working independently with large code libraries and databases,
utilizing atmospheric observations, and producing visualizations, and
collaborating within a team from diverse cultural and racial backgrounds.

Per normal postdoctoral appointment policies, all positions are envisioned
as being initially for 2-years, with extension possible contingent upon
performance and availability of funding.

*UC San Diego is an Equal Opportunity / Staff Affirmative Action Employer.*
