Description:

The NASA Global Modeling and Assimilation Office (GMAO) maintains and develops models of the earth system and its components for an earth system analysis and coupled data assimilation. Accurate exchange of heat, momentum and mass across the air-sea interface, between the atmosphere-, ocean-, land- and sea ice is essential for realistic simulations and data assimilation in an earth system model and analysis. This present opportunity invites proposals that are focused on improving parameters within the bulk-flux formulae that are commonly used in ocean, sea ice and coupled simulations. Such parameters have been derived from a limited set of field campaign measurements. Investigations whose goals include (but not limited to):

1. Study the impact of choice of bulk-flux parameterization and parameters on upper- and deep-ocean, air-sea fluxes,
2. Use machine learning methods to identify and improve values of parameters, which ultimately improve simulations at multiple horizontal resolutions in global and/or regional configurations,
3. Evaluate improvements using NASA's satellite and reanalysis data in different ocean basins with a focus on polar oceans

are highly encouraged.
