The Department of Atmospheric Chemistry at the National Center for
Atmospheric Research (NCAR) is seeking a Postdoctoral Researcher in Air
Quality Modeling and Data Assimilation.
Basic Function of Job: The Postdoctoral Researcher will engage in
multidisciplinary research focused on investigating the effect of
tropospheric clouds on photochemistry and ozone formation. In
particular, he/she will conduct original research to quantify the bias
in ozone predictions that can be explained by inaccurate predictions of
clouds. He/she will perform WRF-Chem model simulations and compare them
with observations from recent field campaigns (SEAC4RS and DISCOVER-AQ)
to assess model performance in simulating actinic fluxes, photolysis
rates and ozone over the continental U.S. under various cloud
conditions. He/she will work on improving the representation of clouds
and radiation in the WRF-Chem model through data assimilation, and will
assess the sensitivity of ozone predictions to those improvements.
Specific duties include:
- Perform WRF-Chem simulations over the continental U.S. and evaluate
model ability to simulate actinic fluxes and photolysis rates for
contrasting clear-sky vs. cloudy conditions using field campaign data.
Acquire, process and analyze the SEAC4RS and DISCOVER-AQ data.
- Assess the effect of cloud data assimilation on photolysis and ozone
predictions. Couple the Multi-sensor Advection-Diffusion nowCast
(MADCast)-GSI system with the WRF-Chem model. Evaluate the impact of
satellite-corrected clouds on photochemistry and ozone predictions.
- Communicate the results of the research through publication in
peer-reviewed journals, meeting proceedings, presentations at scientific
meetings, and contributions to scientific assessments.
The ideal candidate will have a background in atmospheric modeling, data
assimilation and a demonstrated record of research in areas relevant to
this position. The candidate should also have extensive experience with
data analysis and visualization tools (including the ability to program
in Fortran and e.g. NCL/IDL/Matlab) and numerical models (e.g. WRF
and/or WRF-Chem). This appointment may be renewed annually for a maximum
of three years, contingent upon satisfactory performance and the
availability of research funds.
Review of complete applications will begin March 20, 2015; however, the
position will remain open until filled.
