The Joint Effort for Data Assimilation Integration (JEDI) is a generic data assimilation (DA) software infrastructure developed at the Joint Center for Satellite Data Assimilation (JCSDA) to facilitate and eventually expedite transfer between research and operation. The JCSDA is also spearheading a JEDI based marine DA effort for NOAA-EMC and NASA-GMAO, for the initialization of the ocean and sea ice component of the Unified Forecast System (UFS) and the Goddard Earth Observing System (GEOS). This presentation will briefly describe the scope of the marine DA effort at the JCSDA and focus on the specific application of the JEDI to the initialization of the marine components of the UFS for NOAA’s Next Generation Global Ocean Data Assimilation System (NG-GODAS). The NG-GODAS is a joint effort between NOAA-EMC, NOAA-CPC and the JCSDA, the first objective is to replace the aging GODAS based ocean sea ice reanalysis.
