Regional Ensemble Prediction System

Regional Ensemble Prediction System The Regional Ensemble Prediction System (REPS) carries out physics calculations to arrive at probabilistic predictions of atmospheric elements from the current day out to 3 days into the future. The probabilistic predictions are based on 20 ensemble members that are perturbed through their initial and boundary conditions as well as physical tendencies. A control member that is not perturbed is also available. Atmospheric elements include temperature, precipitation, cloud cover, wind speed and direction, humidity and others. This product contains raw numerical results of these calculations. Geographical coverage includes Canada and the United States. Data is available at a horizontal resolution of 10 km. Data is available on ten vertical levels. Predictions are performed four times a day. 2024-04-04 Environment and Climate Change Canada ECWeather-Meteo@ec.gc.ca Nature and EnvironmentScience and TechnologyProbabilistic predictionsRegionalEnsemblePrecipitationAir temperatureWeather forecastsHumiditySnowMeteorological dataWindWeather and ClimateProvide Weather Information Products and ServicesDeliver Weather Products and Services to ClientsMeteorological Service of CanadaWeather and Environmental OperationsUnclassifiedInternational MSC DatamartGRIB2 https://dd.weather.gc.ca/ensemble/reps/10km/ MSC DatamartGRIB2 https://dd.meteo.gc.ca/ensemble/reps/10km/ MSC Datamart AMQPGRIB2 amqps://dd.weather.gc.ca/ensemble.reps.10km.# MSC Datamart AMQPGRIB2 amqps://dd.meteo.gc.ca/ensemble.reps.10km.# REPS.DIAG.6_PRMM.ERGE10 - Quantity of precipitation >= 10 mm [probability %]WMS https://geo.meteo.gc.ca/geomet?lang=fr&service=WMS&request=GetCapabilities&layers=REPS.DIAG.6_PRMM.ERGE10 REPS.DIAG.6_PRMM.ERGE10 - Quantity of precipitation >= 10 mm [probability %]WMS https://geo.weather.gc.ca/geomet?lang=en&service=WMS&request=GetCapabilities&layers=REPS.DIAG.6_PRMM.ERGE10 MSC Open Data documentationHTML https://eccc-msc.github.io/open-data/msc-data/nwp_reps/readme_reps_en/ MSC Open Data documentationHTML https://eccc-msc.github.io/open-data/msc-data/nwp_reps/readme_reps_fr/
