Derived data products

Access derived climate products generated from historical climate station data and/or climate model output.

  • Historical climate indices

    Derived historical temperature and precipitation indices

    Access derived historical temperature and precipitation indices based on daily adjusted and homogenized climate datasets. Please see the technical notes and the definitions table for more details.

  • Projected climate extreme indices

    Climate extreme indices based on climate model output

    Climate extreme indices are computed for a number of global climate models which participated in the Coupled Model Intercomparison Project Phase 3 (CMIP3) and Phase 5 (CMIP5). See the definitions of the core climate extreme indices.

  • High resolution projected climate indices

    Statistically downscaled climate indices

    Access high-resolution statistically downscaled climate indices based on model projections from 24 global climate models (GCMs) that participated in the Coupled Model Intercomparison Project Phase 5 (CMIP5).

  • Coastal wind and wave statistics and extreme indices

    Wind and wave statistics and extreme indices for four Canadian coastal regions

    The Climatological and Sea State Study Summary Report examines recent and projected changes in wind and wave climatology for four coastal regions: Area 1 - Southern portion of British Columbia; Area 2 - St. Lawrence (Montreal to Anticosti Island); Area 3 - Saint John and the Bay of Fundy; and Area 4 - Port Hawkesbury and the Strait of Canso. The full report is only available in English. Please email us at ec.ccds.info-info.dscc.ec@canada.ca for more details.

    For each area, wind and wave statistics and extreme indices were calculated and analyzed to assess historical trends and possible future changes. The historical period is 1980-2015 for Area 1 and 1954-2015 for Areas 2-4. Possible future changes for the mid-range (RCP4.5) and high (RCP8.5) global greenhouse gas emission scenarios are based on simulations from four CMIP5 climate models with a 1° resolution for future waves. This information is intended to inform marine and coastal communities of historical and future climate states in these areas of relevance to marine safety and navigation, shore-based infrastructure and spill and recovery operations.
