CEPENDANT, LES NOMS ET LE CONTENU DE CES PRODUITS SRPD NE SERONT PAS MODIFIES. EN OUTRE, LE SYSTEME DE PREVISION FIREWORK SERA FUSIONNE AVEC LE SYSTEME SRPDQA, CE QUI SIGNIFIE QUE LES PANACHES DE FUMEE DES INCENDIES DE FORET SERONT GENERES DIRECTEMENT DANS LE NOUVEAUX SRPDQA, SELON UNE NOUVELLE METHODE PRENANT EN COMPTE LA COMPOSITION DES PANACHES. AUSSI, LES VALEURS DE LA COTE AIR SANTE BASEES SUR LES OBSERVATIONS DE POLLUANTS SERONT TRAITEES PLUS RAPIDEMENT ET VISIBLES AU PUBLIC PLUS TOT. VEUILLEZ NOTER QU'IL EST POSSIBLE QUE CETTE MISE EN OEUVRE ENTRAINE DE COURTS RETARDS DANS L'HEURE DE DISPONIBILITE DE CERTAINS PRODUITS, PAR EXEMPLE JUSQU'A 10 MINUTES POUR CERTAINS PRODUITS DU SRPD, MAIS DES EFFORTS SONT EN COURS POUR MINIMISER CES RETARDS AUTANT QUE POSSIBLE. BIEN QUE NOUS ANTICIPIONS D'EVENTUELS RETARDS, NOUS PREVOYONS DE RESPECTER LES SEUILS ETABLIS APRES LA MISE EN SERVICE DE L'INFRASTRUCTURE DE CALCUL HAUTE PERFORMANCE ACTUELLE EN SEPTEMBRE 2017. VEUILLEZ ADDRESSER VOS QUESTIONS PARTICULIERE AU SUJET DE CETTE IMPLEMENTATION AU (EN LETTRES MINISCULES) : F.PRODUCTION-INFO.F(AT)EC.GC.CA ------------------ MAJOR UPGRADES TO WEATHER AND ENVIRONMENTAL PREDICTION SYSTEMS AT THE METEOROLOGICAL SERVICE OF CANADA ON TUESDAY, JUNE 11, 2024, STARTING WITH THE 1200 UTC MODEL RUNS, THE CANADIAN METEOROLOGICAL CENTRE (CMC) OF THE METEOROLOGICAL SERVICE OF CANADA (MSC) WILL IMPLEMENT MAJOR UPGRADES TO ITS WEATHER AND ENVIRONMENTAL PREDICTION SYSTEMS. THESE UPDATES ARE THE RESULT OF YEARS OF RESEARCH, DEVELOPMENT, AND TECHNOLOGY TRANSFER AND WILL PERMIT THE ADDITION OF NUMEROUS INNOVATIONS IN MORE THAN 35 ATMOSPHERIC, OCEANIC, HYDROLOGICAL, AND SURFACE FORECASTING SYSTEMS. FOR DETAILED INFORMATION ON THE INNOVATIONS AND THE RESULTING IMPACTS ON SERVICES THAT ARE REALIZED WITH THESE UPGRADES, PLEASE REFER TO THE MSC OPEN DATA WEB PORTAL AT THE FOLLOWING LINK (IN LOWER CASE): HTTPS://ECCC-MSC.GITHUB.IO/OPEN-DATA/MSC-DATA/CHANGELOG_NWP_EN/ ON THIS SITE, FOR EACH OF THE PREDICTION SYSTEMS, YOU WILL SOON BE ABLE TO ACCESS INDIVIDUAL ANNOUNCEMENTS THAT CONTAIN SUMMARIES AND LINKS TO TECHNICAL DOCUMENTS. THE PREDICTION SYSTEMS THAT WILL BE UPGRADED ON JUNE 11 INCLUDE: - GDPS: GLOBAL DETERMINISTIC PREDICTION SYSTEM - RDPS: REGIONAL DETERMINISTIC PREDICTION SYSTEM - GEPS: GLOBAL ENSEMBLE PREDICTION SYSTEM - REPS: REGIONAL ENSEMBLE PREDICTION SYSTEM - HRDPS-NATIONAL: HIGH RESOLUTION DETERMINISTIC PREDICTION SYSTEM - NATIONAL DOMAIN - HRDPS-NORTH: HIGH RESOLUTION DETERMINISTIC PREDICTION SYSTEM - NORTH DOMAIN (EXPERIMENTAL) - HRDPS-WEST: HIGH RESOLUTION DETERMINISTIC PREDICTION SYSTEM - WEST DOMAIN (EXPERIMENTAL) - RAQDPS: REGIONAL AIR QUALITY DETERMINISTIC PREDICTION SYSTEM - RDAQA: REGIONAL DETERMINISTIC AIR QUALITY ANALYSIS - CANSIPS: CANADIAN SEASONAL TO INTER-ANNUAL PREDICTION SYSTEM - GIOPS: GLOBAL ICE OCEAN PREDICTION SYSTEM - RIOPS: REGIONAL ICE OCEAN PREDICTION SYSTEM - CIOPS: COUPLED ICE OCEAN PREDICTION SYSTEM (EAST AND WEST DOMAINS) - WCPS: WATER CYCLE PREDICTION SYSTEM - GDWPS: GLOBAL DETERMINISTIC WAVE PREDICTION SYSTEM - GEWPS: GLOBAL ENSEMBLE WAVE PREDICTION SYSTEM - RDWPS: REGIONAL DETERMINISTIC WAVE PREDICTION SYSTEM - REWPS: REGIONAL ENSEMBLE WAVE PREDICTION SYSTEM - GDSPS: GLOBAL DETERMINISTIC STORM-SURGE PREDICTION SYSTEM - RESPS: REGIONAL ENSEMBLE STORM-SURGE PREDICTION SYSTEM - RDPA-CAPA: REGIONAL DETERMINISTIC PRECIPITATION ANALYSIS - HRDPA-CAPA: HIGH RESOLUTION DETERMINISTIC PRECIPITATION ANALYSIS - HREPA-CAPA: HIGH RESOLUTION ENSEMBLE PRECIPITATION ANALYSIS (EXPERIMENTAL) - OPHS: OPERATIONAL HYDRODYNAMIC PREDICTION SYSTEM - CALDAS-NSRPS: CANADIAN LAND DATA ASSIMILATION SYSTEM - NATIONAL SURFACE AND RIVER PREDICTION SYSTEM (EXPERIMENTAL) - HRDLPS: HIGH RESOLUTION DETERMINISTIC LAND-SURFACE PREDICTION SYSTEM (EXPERIMENTAL) - HRELPS: HIGH RESOLUTION ENSEMBLE LAND-SURFACE PREDICTION SYSTEM (EXPERIMENTAL) - DHPS: DETERMINISTIC HYDROLOGICAL PREDICTION SYSTEM (EXPERIMENTAL) - EHPS: ENSEMBLE HYDROLOGICAL PREDICTION SYSTEM (EXPERIMENTAL) NOTABLY, THE HORIZONTAL RESOLUTION OF GEPS FORECASTS WILL BE INCREASED FROM 39 KM TO 25 KM, AND FORECAST PRODUCTS FROM THE RDPS WILL HENCEFORTH BE GENERATED BY THE GDPS. HOWEVER, THERE WILL BE NO CHANGES TO THE NAMING OR CONTENT OF THESE PRODUCTS. FURTHERMORE, THE FIREWORK PREDICTION SYSTEM WILL BE MERGED WITHIN THE RAQDPS SYSTEM MEANING THAT WILDFIRE SMOKE PLUMES WILL BE GENERATED DIRECTLY IN THE NEW RAQDPS, USING A NEW METHOD CONSIDERING THE PLUMES' COMPOSITION. ALSO, THE VALUES OF THE AIR QUALITY HEALTH INDEX BASED ON POLLUTANT OBSERVATIONS WILL BE PROCESSED MORE RAPIDLY AND VISIBLE EARLIER TO THE PUBLIC. PLEASE NOTE THAT IT IS POSSIBLE THAT THIS IMPLEMENTATION WILL RESULT IN SHORT DELAYS IN TERMS OF THE AVAILABILITY TIME OF SOME PRODUCTS, FOR EXAMPLE, UP TO 10 MINUTES LATER FOR CERTAIN RDPS PRODUCTS, BUT EFFORTS ARE UNDERWAY TO MINIMIZE THESE DELAYS AS MUCH AS POSSIBLE. WHILE WE ANTICIPATE POSSIBLE DELAYS, WE DO EXPECT TO ADHERE TO THE THRESHOLDS THAT WERE ESTABLISHED FOLLOWING THE COMMISSIONING OF THE CURRENT HIGH-PERFORMANCE COMPUTING INFRASTRUCTURE IN SEPTEMBER 2017.
