The CMA global ensemble prediction system was upgraded on 26 December, 2018. The first updated CMA outputs for TIGGE archive have been ingested only since 1 June 2020. The main changes in this upgrade are: - The forecast model system is changed from TL639 L60 to GRAPES_GFS, correspondingly, the horizontal resolution is changed to 50km, and the model top is changed to 3hPa.
- The initial perturbation method is changed from Bred Vector to Singular Vector.
- The SKEB is introduced in the model perturbations.
- The ensemble size is changed from 15 to 31.

The ECCC global ensemble prediction system (origin cwao in the TIGGE archive) was upgraded on July 3 2019. The main changes in this upgrade are: - The horizontal resolution of the Global Deterministic Prediction System (SGPD) is reduced from 25km to 15km, and the number of vertical levels is increased from 80 to 84 levels.
- The atmospheric component of the Global Ensemble Prediction System (GEPS) is now coupled with the ocean-ice model.
- The horizontal resolution of the Regional Ensemble Prediction System (REPS) increases from 15km to 10km, with an increase in the output frequency from 2 to 4 runs per day.
Full details of the changes made to the various systems are available in this official page.
