Abstract:

The Joint Effort for Data Assimilation Integration (JEDI) system is a next-generation data assimilation system developed collaboratively by the Joint Center for Satellite Data Assimilation (JCSDA) and its partners. JEDI provides a generic, model-agnostic framework that enables the development of shared data assimilation capabilities across a wide range of models and applications. It has been interfaced with multiple forecast models in the atmospheric, oceanic, and aerosol domains, and is now being extended to support space weather applications. It is slated for adoption by several major numerical weather prediction (NWP) centers, including NOAA, NASA, NRL, and the UK Met Office. Some components of JEDI, such as the ocean and sea ice data assimilation, are already in operational use.

This seminar will begin with a brief overview of general data assimilation concepts, followed by an introduction to the JEDI system and its architecture. Selected examples will be presented to highlight JEDI’s versatility in supporting the evaluation of new observations and impact studies across diverse applications.
