Environment and Climate Change Canada

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Snow cover indicator shows how Canada's snow cover is changing from year-to-year and over time. Snow cover extent is...

Meteorological forecasts are datasets that are products of current observations and are used to predict climate conditions for a future time and given location.

This dataset contains 21 statistics (including extreme indices) of wind and waves calculated from hourly reanalysis data of historical surface winds and ocean surface waves for the Davis Strait Baffin Bay waters for the period 1979-2018 (each statistic has an annual and 12 monthly values). These...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The indicators show trends in anthropogenic (human-made) greenhouse gas (GHG) emissions. It includes emissions for 7...

Projected change in wind speed is with respect...

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...

Multi-model ensembles of mean precipitation based on projections from twenty-nine Coupled Model Intercomparison Project Phase 5 (CMIP5) global climate models are available for 1901-2100. Specifically, the 5th, 25th, 50th, 75th and 95th percentiles of the monthly, seasonal and annual ensembles of...

Anomalous weather resulting in Temperature and Precipitation extremes occurs almost every day somewhere in Canada. For the purpose of identifying and tabulating daily extremes of record for temperature, precipitation and snowfall, the Meteorological Service of Canada has threaded or put together...

Climate Normals and Averages are used to summarize or describe the average climatic conditions of a particular location. At the completion of each decade, Environment and Climate Change Canada updates its Climate Normals for as many locations and as many climatic characteristics as possible. The...
