Where You Will Work:

Located in Boulder, Colorado, the National Center for Atmospheric Research
(NCAR) is one of the world's premier scientific institutions, with an
internationally recognized staff and research program dedicated to advancing
knowledge, providing community-based resources, and building human capacity
in the atmospheric and related sciences.  NCAR is sponsored by the National
Science Foundation (NSF) and managed by the University Corporation for
Atmospheric Research (UCAR).

Formed in 2005, the  <https://www.eol.ucar.edu/about-eol> Earth Observing
Laboratory (EOL) the is one of the seven laboratories of
<https://ncar.ucar.edu/> NCAR, the National Science Foundation's Federally
Funded Research and Development Center. EOL's mission is to provide
leadership in observing facilities, field project support as well as
research and data services needed to advance the scientific understanding of
the Earth system. EOL manages the majority of NSF's Lower Atmosphere
Observing Facilities (LAOF) and deploys them in support of observational
field campaigns, ranging from single investigator projects to large complex
campaigns that involve multiple investigators, agencies, and platforms,
nationally and internationally. EOL deploys its systems for research by
scientists from universities, NCAR, and government agencies, as well as for
education. An integral part of EOL's mission is to develop the next
generation of LAOF and to provide management and archiving of data from past
supported campaigns. In order to ensure progress in the atmospheric
sciences, EOL supports a wide-range of research areas within the Earth
system science, ranging from microscale to mesoscale to climate process
studies, and employs LAOF platforms and systems that reach from the surface
of the Earth to the lower stratosphere and beyond. 

EOL's  <https://www.eol.ucar.edu/facilities/remote-sensing-facility-rsf>
Remote Sensing Facility's (RSF) mission is to serve the observational needs
of the atmospheric science community by developing and deploying
state-of-the-art radar and lidar instrumentation. RSF is committed to
providing and analyzing cross-cutting measurements in interdisciplinary
research thereby continuing EOL's leadership in the discipline of remote
sensing. The combination of ground-based scanning and airborne remote
sensors provides measurements of atmospheric parameters essential for
realization of the societal and scientific benefits outlined in the EOL
Strategic Plan. These high-resolution, large-domain, remotely-sensed
observations of clear air and precipitation are otherwise unobtainable.

What You Will Do:

Acquire post-graduate research experience while also fulfilling the
deliverables of a grant to study the impact of assimilating water vapor,
temperature and wind profiling data on improving numerical weather
prediction forecast skill.  Research is directed by project PIs and includes
pre-defined research objectives and deliverables. 

Responsibilities:

.        Conduct independent and collaborative research in data assimilation
(DA) that addresses the project goals to assimilate moisture profiles from a
state-of-the-art network of MicroPulse water vapor differential absorption
lidars (MPD), water vapor and temperature profiles from Atmospheric Emitted
Radiance Interferometers (AERI) and wind profiles from Doppler lidars (DL).
Research will focus on the best practices of assimilation of thermodynamic
and wind profiles into convection-allowing Weather Research and Forecast
Data Assimilation (WRFDA), Ensemble Kalman filtering data assimilation via
the Data Assimilation Research Testbed (DART) and/or hybrid DA with a
development version of the High-Resolution Rapid Refresh (HRRR). Work will
include: (1) development of best methods to combine and assimilate MPD, AERI
and DL profiles and (2) evaluation of observation impact from profile data
to improve short-term, high-impact weather forecasting skill.

.        Establish verification procedures to (1) quantify observation
impact from the combined water vapor, temperature and wind profiles and (2)
quantify observation impact from the individual observing instruments.

.        Prepare results for publication in peer-reviewed journals and for
presentation at meetings and conferences.  Prepare and deliver summary
reports or contribute toward project progress reports as needed.

.        Serve as the link to facilitate collaboration between MMM data
assimilation experts, EOL instrumentation experts, and NOAA operational
requirements.

.        The above statements describe the primary work being performed.
Additional tasks may be assigned from time to time.

What You Need:

Education and Years of Experience:

.        Ph.D. within the last 5 years in atmospheric science, oceanography,
hydrology, mathematics, statistics or a related area.

Knowledge, Skills, and Ability

.        Demonstrated skill in the analysis and use of atmospheric
observations.

.        Experience with numerical weather prediction or other numerical
prediction for geophysical flows, particularly WRF, FV3 or MPAS.

.        Advanced skills with programming languages and scripting.

.        Knowledge of data assimilation for geophysical systems.

.        Knowledge of research instruments, measurements and data quality
control procedures. 

.        Ability to work with Linux/Unix operating systems and display
tools.

.        Skill in oral and written communication.

.        Ability to work both independently and collaboratively as part of a
diverse research team.
