Dear Colleagues,

 

The Atmospheric Sciences and Global Change division at Pacific Northwest National Laboratory (PNNL) is seeking highly motivated postdoctoral research associates for 2 positions.

 

The candidate for the first position (307761) will develop a better understanding of deep convective initiation, organization, dynamics, and microphysics for the purpose of improving its parameterization in multi-scale models.  In particular, potential environmental predictors of convective transitions and life cycle properties for a significant number of events will be analyzed along with key microphysical processes that impact convective cloud macrophysical evolution. Two-way interactions of microphysical processes with convective circulations such as updrafts, downdrafts, and cold pools on fine spatiotemporal scales are of particular interest. Data from the recent CACTI and RELAMPAGO campaigns in Argentina will be used.  The ability of multi-scale models and variable complexity physics parameterizations to capture observed cloud and environmental processes critical to predicting the convective life cycle will be examined and sources for potential biases will be established through model sensitivity experiments. Additionally, the postdoc may contribute to analyzing the ability of models to reproduce observed impacts of convective clouds and precipitation on surface properties, aerosol redistribution, and boundary layer evolution with feedbacks to subsequent convective cloud development.

 

The candidate for the second position (3068510) will develop a better understanding and model source-receptor relationships of atmospheric contaminants.  In collaboration with researchers in the Atmospheric Measurement and Data Science and Radiation Detection and Nuclear Sciences groups, the successful applicant will:
• simulate the transport, turbulent mixing, and removal of materials released into the atmosphere using predictive models such as WRF
• evaluate the performance of models using observations, 
• design future measurement strategies, 
• better understand the fundamental processes affecting atmospheric dispersion over multiple spatial and temporal scales, and 
• publish findings in scientific journals.

For both positions, It will be essential for the candidate to make the commitment to developing and maintaining robust, clean, and easily maintainable codes and scripts. Teamwork and strong communication skills for engaging with project members at PNNL and other national laboratories will also be very important.
