Adjusted Precipitation (AHCCD)

Adjusted Precipitation (AHCCD) The Adjusted Precipitation data consist of monthly, seasonal and annual totals of daily adjusted rain, snow and total precipitation (millimetres) for 464 locations in Canada. Adjusted precipitation data incorporate adjustments (derived from comparison of instruments) to the original station data to account for discontinuities from non-climatic factors, such as instrument changes or station relocation. The time periods of the data vary by location, with the oldest data available from the early 1880s at some stations to the most recent update in 2017. Observations at co-located sites were sometimes joined in order to create longer time series. Data availability over most of the Canadian Arctic is restricted to the mid-1940s to present. 2025-03-20 Environment and Climate Change Canada ec.ccds.info-info.dscc.ec@canada.ca Nature and EnvironmentScience and Technologyprecipitation; adjusted; climate; climate changeClimateClimate changeWeather and ClimateProvide Climate Information Products and ServicesExpand Scientific Knowledge for Climate Monitoring and PredictionNational (CA)Science and Technology BranchAtmospheric Science and TechnologyUnclassified Adjusted / homogenized climate data ENHTML https://climate-scenarios.canada.ca/index.php?page=homogenized-data AHCCD AnnualWFS https://api.weather.gc.ca/collections/ahccd-annual?lang=fr AHCCD MonthlyWFS https://api.weather.gc.ca/collections/ahccd-monthly?lang=fr AHCCD TrendsWFS https://api.weather.gc.ca/collections/ahccd-trends?lang=fr AHCCD SeasonalWFS https://api.weather.gc.ca/collections/ahccd-seasonal?lang=fr AHCCD StationsWFS https://api.weather.gc.ca/collections/ahccd-stations?lang=fr Adjusted / homogenized climate data FRHTML https://scenarios-climatiques.canada.ca/index.php?page=homogenized-data View Data MartHTML https://dd.weather.gc.ca/climate/ahccd View Data MartHTML https://dd.meteo.gc.ca/climate/ahccd Climate Data ViewerHTML https://climate-viewer.canada.ca/climate-maps.html Climate Data ViewerHTML https://visualiseur-climatique.canada.ca/cartes-climatiques.html Climate Data Extraction ToolHTML https://climate-change.canada.ca/climate-data/#/adjusted-station-data AHCCD StationsWMS https://geo.weather.gc.ca/geomet-climate?service=WMS&version=1.3.0&request=GetCapabilities&layer=AHCCD.STATIONS AHCCD StationsWMS https://geo.weather.gc.ca/geomet-climate?lang=fr&service=WMS&version=1.3.0&request=GetCapabilities&layer=AHCCD.STATIONS AHCCD StationsWFS https://api.weather.gc.ca/collections/ahccd-stations AHCCD AnnualWFS https://api.weather.gc.ca/collections/ahccd-annual AHCCD SeasonalWFS https://api.weather.gc.ca/collections/ahccd-seasonal AHCCD TrendsWFS https://api.weather.gc.ca/collections/ahccd-trends AHCCD MonthlyWFS https://api.weather.gc.ca/collections/ahccd-monthly View ECCC Data Mart (English)HTML https://data-donnees.ec.gc.ca/data/climate/scientificknowledge/adjusted-and-homogenized-canadian-climate-data-ahccd/adjusted-precipitation-ahccd/ View ECCC Data Mart (French)HTML https://data-donnees.ec.gc.ca/data/climate/scientificknowledge/adjusted-and-homogenized-canadian-climate-data-ahccd/adjusted-precipitation-ahccd/?lang=fr Data Collection MethodologyHTML https://www.canada.ca/en/environment-climate-change/services/climate-change/canadian-centre-climate-services/display-download/technical-documentation-adjusted-climate-data.html Data Collection MethodologyHTML https://www.canada.ca/fr/environnement-changement-climatique/services/changements-climatiques/centre-canadien-services-climatiques/afficher-telecharger/documentation-technique-donnees-climatiques-ajustees.html
