Homogenized Surface Pressure (AHCCD) The Homogenized Surface Pressure data consist of monthly, seasonal and annual means of hourly sea level and station pressure (hectopascals) for 626 locations in Canada. Homogenized climate data incorporate adjustments (derived from statistical procedures) 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 1953 at some stations to the most recent update in 2014. Data availability over most of the Canadian Arctic is restricted to 1953 to present. The data will continue to be updated every few years (as time permits). 2018-09-06 2018-10-02 Environment and Climate Change Canada ec.ccds.info-info.dscc.ec@canada.ca Nature and EnvironmentScience and Technologysurface pressure; homogenized; climate; climate changeWeather and ClimateProvide Climate Information Products and ServicesExpand Scientific Knowledge for Climate Monitoring and PredictionNational (CA)ClimateClimate change Adjusted / homogenized climate data ENHTML http://climate-scenarios.canada.ca/index.php?page=homogenized-data Adjusted / homogenized climate data FRPDF http://scenarios-climatiques.canada.ca/index.php?page=homogenized-data Data Collection MethodologyPDF http://data.ec.gc.ca/data/climate/scientificknowledge/adjusted-and-homogenized-canadian-climate-data-ahccd/homogenized-surface-pressure-ahccd/AHCCD_-_READ_ME_Technical_doc_EN.pdf Data Collection MethodologyPDF http://data.ec.gc.ca/data/climate/scientificknowledge/adjusted-and-homogenized-canadian-climate-data-ahccd/homogenized-surface-pressure-ahccd/AHCCD_-_READ_ME_Technical_doc_FR.pdf View Data MartHTML http://dd.weather.gc.ca/climate/ahccd View Data MartHTML http://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://geo.weather.gc.ca/geomet-beta/features/collections/ahccd-stations AHCCD AnnualWFS https://geo.weather.gc.ca/geomet-beta/features/collections/ahccd-annual AHCCD SeasonalWFS https://geo.weather.gc.ca/geomet-beta/features/collections/ahccd-seasonal AHCCD TrendsWFS https://geo.weather.gc.ca/geomet-beta/features/collections/ahccd-trends AHCCD MonthlyWFS https://geo.weather.gc.ca/geomet-beta/features/collections/ahccd-monthly View ECCC Data Mart (English)HTML http://data.ec.gc.ca/data/climate/scientificknowledge/adjusted-and-homogenized-canadian-climate-data-ahccd/homogenized-surface-pressure-ahccd View ECCC Data Mart (French)HTML http://data.ec.gc.ca/data/climate/scientificknowledge/adjusted-and-homogenized-canadian-climate-data-ahccd/homogenized-surface-pressure-ahccd?lang=fr
