The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly‑talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA‑affiliated research institute. These one‑to‑three‑year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

Prediction on subseasonal to seasonal time scales is societally relevant and the fidelity of these predictions has improved in recent years. Assessing the prediction skill and source of error, as well as the sources predictability in the atmosphere and in the ocean, is critical to advancing seasonal prediction skill.

The Global Modeling and Assimilation Office (GMAO)’s Goddard Earth Observing System (GEOS) seasonal prediction model and data assimilation system (GEOS‑S2S) is currently being used to produce MERRA-2 Ocean, a 1982‑present weakly coupled reanalysis. Proposals are invited for investigations using MERRA-2 Ocean and/or the Estimating the Circulation and Climate of the Ocean (ECCO) reanalysis and the associated ocean "analysis increments" to assess the errors in the coupled earth system model predictions due to the combination of local and remote effects.

GMAO has a particular interest in proposals that focus on the northern hemisphere high latitude regions based on the relevance for sea ice prediction.
