<span lang="EN" style="font-size: 12pt; font-family: "Times New Roman", serif;">The Atmospheric and Oceanic Sciences Program at Princeton University, in association with NOAA's Geophysical Fluid Dynamics Laboratory (GFDL), seeks a postdoctoral or more senior
research scientist to conduct research on developing and using machine learned parameterizations developed from ocean-data assimilation increments. The goal is to develop parameterizations of unresolved processes that will improve ocean circulation models.
A neural network has already been demonstrated to model the misfit between the ocean model and observations. The new research will involve training a new machine-learned model to represent some missing physics contained within this dataset, interpret the new
model, implement it as a parameterization in a global circulation model (MOM6), and evaluate the new parameterization within a global-scale climate model.<o:p></o:p></span></p>

<span lang="EN" style="font-size: 12pt; font-family: "Times New Roman", serif;">The work is part of a larger project, M2LInES, covering eleven institutions. The overall goal is to reduce climate model biases at the air-sea/ice interface by improving subgrid
physics in the ocean, sea ice and atmosphere components of existing coarse (¼° to 1°) resolution IPCC-class climate models, and their coupling, using machine learning. This part of the research at Princeton University/GFDL will involve working with the SPEAR
ocean data assimilation system and the MOM6 ocean circulation model. The prognostic parameterizations will be state-dependent and trained to minimize model-observation misfits with the aim of reducing inherent biases in free-running climate simulations. The
research will require analysis and interpretation of model output, the management of large datasets and the application of neural nets or other machine learning techniques to those data. The postdoc will be expected to collaborate with other postdocs at Princeton
and with other members of the M2LInES project across multiple institutions.<o:p></o:p></span></p>
