What are the responsibilities and job description for the Physical Scientist and Ensemble Modeler for Atmospheric River Forecasting position at Lynker?
Lynker is seeking a talented Physical Scientist and Ensemble Modeler for Atmospheric River Forecasting, to support the Environmental Modeling Center (EMC) of the National Centers for Environmental Prediction (NCEP) in carrying out research and development work related to the Unified Forecast System (UFS) based Atmospheric River Forecasting System..
The Physical Scientist and Ensemble Modeler will support the Water in the West initiative by supporting the development and implementation of the On-Demand Regional Atmospheric River Ensemble Forecast System (AR-EFS) within the Unified Forecast System (UFS) framework. The position focuses on advancing ensemble-based regional modeling, developing data assimilation and post-processing techniques, and preparing the system for real-time applications and potential transition to NWS operations.
Duties of the Physical Scientist and Ensemble Modeler for Atmospheric River Forecasting will include the following
The candidate will perform their job duties to a high standard, working both independently and collaboratively. They will assist in managing projects and in developing and applying innovative methods within the primary work areas outlined below. The candidate will collaborate with EMC scientists and external partners to calibrate, optimize, and evaluate the UFS-based Atmospheric River Forecasting systems. The primary focus will be on designing and developing ensemble modeling capabilities for Atmospheric River forecasts, including development of advanced algorithm enhancements, physical parameterization schemes, and data assimilation.
The successful candidate will work on supporting the following scientific and engineering tasks
