Job Details
Overview:
Are you interested in improving the ability of Earth system models to simulate energy, water, carbon, and biogeochemical cycles in the Arctic? The Next Generation Ecosystem Experiments in the Arctic (NGEE Arctic) project at Oak Ridge National Laboratory (ORNL) has a position open now for a postdoctoral researcher with a background in multiscale modeling and model-data integration. The goal for this position is to apply knowledge gained over the past twelve years from multiple intensively studied field sites in Alaska to the development and evaluation of new land processes in an Earth system model at the pan-Arctic scale.
You will work as an integral part of the large and collaborative NGEE Arctic team and will play a critical role in integrating new Arctic ecosystem process knowledge into the DOE’s Energy Exascale Earth System Model (E3SM). As the NGEE Arctic project moves into its fourth and final phase the science focus is on improved process representation at multiple spatial scales up to and including the pan-Arctic. Multiple process representations have already been developed and evaluated, independently, at site scales. In Phase 4 we will explore the integrated system behavior with all new process representations operating together. The processes being explored include:
- Improved representation of fractional inundated area under the influence of permafrost thaw in polygonal tundra
- Lateral water transport down hillslopes in regions of continuous and discontinuous permafrost
- Interactions among snow, vegetation, and permafrost during accumulation and melt periods
- New vegetation physiology parameterizations for arctic tundra plant types
- Dynamic tundra vegetation biogeography in response to changing climate
- Improved representation of soil biogeochemical processes in frequently inundated tundra ecosystems
Major Duties/Responsibilities:
- Work with the multiscale modeling team to evaluate combinations of new model capability within the E3SM Land Model (ELM) at site, regional, and pan-Arctic scales
- Configure ELM simulations, perform simulations on high performance computing platforms, evaluate model results against multi-scale observational and experimental data
- Publish results of multi-scale model evaluation
- Work in close collaboration with other NGEE Arctic team members who are developing multi-scale data syntheses
- Deliver on ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service
- Promote diversity, equity, inclusion, and accessibility by fostering a respectful workplace – in how we treat one another, work together, and measure success
Basic Qualifications:
- PhD with training and research experience in Earth system modeling, or closely related training and research experience
- Excellent written and oral communication skills
- Excellent collaboration and teamwork skills
Preferred Qualifications:
- Experience programming in Fortran, C/C++, or similar language
- Experience with complex software systems and build environments. Experience with Unix-like operating systems
- Experience with high-performance computing environments
- Experience working with large model-generated multivariate datasets, especially with netCDF file formats and analysis tools
- Experience with model-data integration, including data aggregation for model evaluation and model configuration for comparison to observations
- Experience working with multi-model, multi-scale simulation environments
- Experience with creation of high-quality graphics for effective communication of research results
Special Requirements:
Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment. The appointment length will be up to 24 months with the potential for extension. Initial appointments and extensions are subject to performance and availability of funding.
Please submit three letters of reference when applying to this position. You may upload these directly to your application or have them sent to Postdocrecruitment@Ornl.gov with the position title and number referenced in the subject line.
