[Met-jobs] Postdoctoral Researcher in Air quality at NCAR

From Alma Hodzic <>
Date Wed, 11 Mar 2015 19:26:07 -0600

Dear colleagues,

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.
