#### Abstract The Joint Center for Satellite Data Assimilation (JCSDA) is developing the Joint Effort for Data assimilation Integration (JEDI). JEDI is built using a generic software infrastructure making it reusable and sharable between weather forecast centers around the World. Unlike legacy data assimilation system JEDI can function using any model grid and set of fields. FV3-JEDI will form the interface between JEDI and the atmospheric components of models formulated using the FV3 (Finite Volume cubed-sphere) dynamical core. These models include NASA’s GEOS model and NOAA’s GFS model. Similarly an interface is being formulated between the ocean and sea-ice components of these models and JEDI. In this talk we will describe the effort towards constructing these systems and report on the progress towards achieving operationally viable data assimilation using the JEDI data assimilation system.
