High Resolution Ensemble Precipitation Analysis [experimental]

High Resolution Ensemble Precipitation Analysis [experimental] HREPA is part of the NSRPS (National Surface and River Prediction System) experimental system dependent on two other systems. It uses surface station observations and radar QPEs pre-processed by HRDPA and disturbed trial fields generated by the Canadian Land Data Assimilation System (CaLDAS). HREPA produces four precipitation analyses per day on 6-hour accumulations valid at synoptic times (00, 06, 12, and 18 UTC). Each analysis set contains 24 members plus the control member. A quality index (confidence index) is also available on the same grid as the precipitation fields. Finally, two percentiles, 25th and 75th, estimated on these sets are also provided for each synoptic hour. Currently, there is only a high-resolution version of the system, whose domain covers Canada and the northern United States with a horizontal resolution of about 2.5km. 2023-05-16 Environment and Climate Change Canada ECWeather-Meteo@ec.gc.ca Nature and EnvironmentScience and TechnologyEnsembleHigh-ResolutionPrecipitationAnalysisProvide Weather Information Products and ServicesDeliver Weather Products and Services to ClientsMeteorological Service of CanadaWeather and Environmental OperationsUnclassifiedInternational MSC DatamartNetCDF https://dd.alpha.weather.gc.ca/model_hrepa/2.5km/ MSC DatamartNetCDF https://dd.alpha.meteo.gc.ca/model_hrepa/2.5km/ MSC Datamart AMQPNetCDF amqps://dd.alpha.weather.gc.ca/model_hrepa.2.5.# MSC Datamart AMQPNetCDF amqps://dd.alpha.meteo.gc.ca/model_hrepa.2.5.#
