Chronology of changes to the Regional Deterministic Wave Prediction System (RDWPS)
Tuesday June 11, 2024
Upgrade to Version 4.2.0 of the Regional Deterministic Wave Prediction System (RDWPS) at the Canadian Meteorological Centre
On Tuesday June 11, 2024, starting with the 1200 UTC run, the Meteorological Service of Canada's Canadian Meteorological Centre (CMC) will upgrade the Regional Deterministic Wave Prediction System (RDWPS) to v4.2.0
Significant changes:
- Use of wind forcings from the latest version of the High Resolution Deterministic Prediction System (HRDPS), v7.0.0
- Use of ice concentration forcings from the latest versions of the Water Cycle Prediction Systems (WCPS), v3.3.0 and the Regional Ice-Ocean Prediction System (RIOPS), v2.4.0
- Ocean domains: correct interpolation of wind to model grid
- Great Lakes domains: activate Miche style shallow water limiter

Monday March 4, 2019
Upgrades to the Regional Deterministic Wave Prediction System (RDWPS) at the Canadian Meteorological Centre (CMC)
Effective March 4, 2019, the Canadian Meteorological Centre (CMC) of the Meteorological Service of Canada will update the Regional Deterministic Wave Prediction System (RDWPS) to v3.2.0.
RDWPS v3.2.0 is different from the previous operational system in that the ice analysis used as input for it has been replaced by an ice forecast provided by the Water Cycle Prediction System (WCPS v2.0.0), which was declared operational on March 4, 2019.
