Global Deterministic Wave Prediction System

Global Deterministic Wave Prediction System The Global Deterministic Wave Prediction System (GDWPS) produces wave forecasts out to 120 hours in the future using the third generation spectral wave forecast model WaveWatch III® (WW3). The model is forced by the 10 meters winds and the ice concentration from the Global Deterministic Prediction System (GDPS). The ice concentration is used by the model to attenuate wave growth in areas covered by 25% to 75% ice and to suppress it for concentration above 75%. Forecast elements include significant wave height, peak period and primary swell height, direction and period. 2024-04-10 Environment and Climate Change Canada ECWeather-Meteo@ec.gc.ca Nature and EnvironmentWavesSwellPredictionGlobalDeterministicForecastingWaterOceansOcean energySeasProvide Weather Information Products and ServicesDeliver Weather Products and Services to ClientsMeteorological Service of CanadaWeather and Environmental OperationsUnclassifiedInternational MSC DatamartGRIB2 https://dd.weather.gc.ca/model_gdwps/ MSC DatamartGRIB2 https://dd.meteo.gc.ca/model_gdwps/ Significant height of wind waves (hourly forecast) [m]WMS https://geo.weather.gc.ca/geomet?lang=en&service=WMS&request=GetCapabilities&layers=GDWPS_25km_WVHGT_PT1H Significant height of wind waves (hourly forecast) [m]WMS https://geo.meteo.gc.ca/geomet?lang=fr&service=WMS&request=GetCapabilities&layers=GDWPS_25km_WVHGT_PT1H MSC Datamart AMQPGRIB2 amqps://dd.weather.gc.ca/model_gdwps.# MSC Datamart AMQPGRIB2 amqps://dd.meteo.gc.ca/model_gdwps.# MSC Open Data documentationHTML https://eccc-msc.github.io/open-data/msc-data/nwp_gdwps/readme_gdwps_en/ MSC Open Data documentationHTML https://eccc-msc.github.io/open-data/msc-data/nwp_gdwps/readme_gdwps_fr/
