Postdoc Fellow at NCAR
Position Term: 1-Year, with the possibility of extension.
Relocation: No relocation package is offered for this position.
Work Authorization: UCAR|NCAR can sponsor a work visa for this position.
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 Earth Observing Laboratory (EOL) the is one of the seven laboratories of 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 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.
- 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.
