Job Description Summary: The Postdoctoral Fellow will contribute to cutting-edge research in satellite data assimilation using the Model for Prediction Across Scales (MPAS) coupled with the Data Assimilation Research Testbed (DART) at NSF NCAR. The fellow will conduct Observing System Simulation Experiments (OSSEs) to evaluate the potential impact of dense cloud-top brightness temperature observations (cloud-top temperature, CTT) on model analyses and forecasts.

This role will also involve refining data preprocessing workflows and updating MPAS/DART interfaces as needed. In addition, the fellow will have the opportunity to contribute to development of MPAS/JEDI (the MPAS interface to the Joint Effort for Data Assimilation Integration framework) for coupled atmosphere-aerosol satellite data assimilation.

This position will sit in MMM (the Mesoscale and Microscale Meteorology Lab).

What You Will Do

Here is a brief summary of what one would expect to be generally responsible for in this role.

+ Conduct independent and collaborative research for OSSE studies with the assimilation of satellite retrievals. This may include developing a data processing tool and improving the interface to the Radiative Transfer for TOVS (RTTOV) within MPAS/DART, as needed. Design and conduct cycling experiments to demonstrate the impact of cloud top temperature (CTT) and analyze the results with scientific interpretation.

+ Contribute to the development of MPAS-GOCART2G-JEDI and execution of cycling experiments, followed by scientific analysis and interpretation of the results.

+ Prepare research results for presentation at conferences and publication in peer-reviewed journals. Assist with the preparation of reports or project progress reports as needed.
