    Notice Inventory

    The Notice Inventory contains a record of all past and current Notices.

    Data Access Tools

    Hydrometric Real-time and Historical Data/Historical Sediment Data

    This site provides public access to real-time hydrometric data collected at over 1 800 locations and access to historical data collected at over 7 600 stations (active and discontinued) in Canada. These data are collected under a national program jointly administered under federal-provincial and federal-territorial cost-sharing agreements.

    Fisheries and Oceans Canada

    Access to historical wave, and weather data from Meteorological Service of Canada moored buoys.

    Adjusted and Homogenized Canadian Climate Data (AHCCD)

    Public access to adjusted and homogenized climate data for many climatological stations in Canada. These data were created for use in climate research including climate change studies. Addition Adjusted and homogenized Canadian climate data (AHCCD) available from MSC Datamart (in GeoJSON format): https://dd.meteo.gc.ca/climate/ahccd/ and documentation: https://dd.meteo.gc.ca/climate/doc/ahccd/README_AHCCD.txt

    MSC Datamart

    The Meteorological Service of Canada (MSC) HTTP data server is a source of several raw meteorological data types and forecast data. This service is aimed at specialized users with good meteorological and IT knowledge, and is mainly meant to be accessed in an automatic manner via the internet (e.g. with scripts).

    Additional climate datasets at MSC Datamart data:

    1) Global climate model scenario data based on an ensemble of projections from the Coupled Model Intercomparison Project Phase 5 (CMIP5), in NetCDF format:

    2) Statistically downscaled climate scenario data (DCS) based on an ensemble of statistically downscaled global climate model projections from the Coupled Model Intercomparison Project Phase 5, in NetCDF format:

    3) Canadian gridded historical climate data, also referred to as Canadian gridded anomalies (CANGRD), interpolated from adjusted and homogenized climate station data (AHCCD), in GeoTIFF format:

    Cartographic Tools/Maps

    Drought Watch (Agriculture and Agri-Food Canada)

    Provides timely information of the impacts of climatic variability on water supply and agriculture using data from Environment and Climate Change Canada and other sources. Products include: current and historical maps of precipitation, temperature, growing degree days and drought indices.

    Atlas of Canada - Natural Resources Canada (Climate)

    Offers information and maps on snow cover, minimum and maximum temperatures, and precipitation. Environment and Climate Change Canada and other data sources are used for the production of these maps.

    Climate Information/Summaries

    Climate Trends and Variations Bulletin

    Climate Trends and Variations Bulletin (CTVB) places the most recent season's or year's temperatures and precipitation values in historical context by utilizing timely data sets from synoptic weather reporting stations in Canada and historical homogenized climate data.
