Description: Performs research with the objective to leverage existing datasets and ongoing deficit and spatial irrigation management projects. Will develop a suite of automated, repeatable processes and tools for precision variable rate irrigation (VRI) decisions in real-time. Will integrate an open-source water balance and evapotranspiration model product 鈥減yfao56鈥� with field data collection, database design, quality control, visualization, and immediate analysis to support real-time precision VRI prescriptions. Will develop products that will be tested and integrated with ongoing research at the USDA-ARS Limited Irrigation Research Farm in Greeley, CO. Will prepare and submit final research results in peer-reviewed journals and presentations at conferences. Open & closing dates: 09/27/2024 to 03/21/2025. Salary: $80,665 - $104,861 per year.

Description: The incumbent will utilize ongoing soil and management data as well as pending sampling efforts, to measure, monitor, report, and validate soil health, C sequestration potential, and GHG fluxes for agricultural systems in the Pacific Northwest (at field and watershed/ regional scales). Ideally, the incumbent will have modeling experience and contribute to the calibration and utilization of a biogeochemical model to estimate how shifts in management impact C sequestration potential. Additionally, the incumbent will contribute to the development of a soil inventory including digital maps and a soil health management index, specific to the grass seed crop system across the region. The incumbent will lead the analyses and manuscript drafts and oversee undergraduate research assistants. Additional hypotheses and research objectives may be developed and tested as part of independent inquiry. Open & closing dates: 07/19/2024 to 12/31/2024. Salary: $78,044 - $101,454 per year. 

Description: The PPGRU's mission is to increase the productivity, profitability and sustainability of agriculture in arid environments by developing new germplasm for both traditional and alternative crops and by improving plant responses to abiotic stresses and to changes in the global environment. Emphasis is placed on oilseeds crops used for food, and biofuels, and establish new industrial and bioenergy crops for semi-arid regions. Salary: $75,783 - $98,515 per year. *ANNOUNCEMENT IS OPEN UNTIL FILLED OR 02/05/2025*

We are seeking Postdoctoral Research Associates who will support the Computational Earth Sciences (CES) Group in the Computational Sciences and Engineering Division (CSED), Computing and Computational Sciences (CCSD) Directorate at Oak Ridge National Laboratory (ORNL). The postdoctoral researcher will conduct research on sub-seasonal to seasonal scale (S2S) predictability and translate the information into useful products for stakeholders to enable decision-support services. The ideal candidate should have a strong understanding of approaches to establishing a predictive understanding of climate variability and change, particularly in global monsoon regions. The candidate should also have experience using global seasonal forecasting systems and developing models for predicting S2S climate through conventional and artificial intelligence approaches. An understanding of the requirements to establish stakeholder-relevant S2S products is also desirable.  Closing date: 10/16/2024. 

Description: CCSI is partnering with Vanderbilt University to launch a new project that will connect our combined science and technology strengths with communities and other stakeholders to serve real-world needs in the Southeast region and beyond. This project is part of a new CCSI initiative called Science and Technology for Applied Regional Solutions (CCSI STARS). The researcher will synthesize and analyze observational data and modeling outputs from multiple Earth system models. The researcher will also evaluate the performance of the Energy Exascale Earth System Model (E3SM) land model (ELM) in Southeast forests using observational data, and execute and analyze high resolution ELM simulations to understand carbon storage and offset potential in SE forest ecosystems under different social-economic and land management scenarios. The researcher will have opportunities to interact with stakeholders to understand and address their needs using research tools and capabilities developed in the project.
