4.1      Data assimilation for MPAS.

Snyder, Chris, and Zhiquan Liu, National Center for Atmospheric Research

Data assimilation capabilities for MPAS include a mature ensemble Kalman filter (EnKF), implemented through the Data Assimilation Research Testbed (DART), and ensemble-variational algorithms implemented through the Joint Effort for Data Assimilation Integration (JEDI).  This presentation will review the status of these efforts, including the development of end-to-end assimilation of satellite radiances via JEDI.
