At the Canadian Meteorological Centre (CMC), an ensemble variational (EnVar) data assimilation system is used for the global deterministic prediction system and an ensemble Kalman filter (EnKF) is used for the global ensemble prediction system. These two systems are co‐developed and co‐evolving at the CMC and in this study we explore how to maximize the impact of having two algorithms.
