title08-07-2019 ECCC

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.
