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...

Monthly, seasonal and annual trends of mean hourly sea level and station pressure change (hectopascals) based on homogenized station data (AHCCD) are available. Trends are calculated using the Theil-Sen method using the station’s full period of available data. The availability of surface pressure...

Statistically downscaled multi-model ensembles of projected change (also known as anomalies) in maximum temperature (°C) are available at a 10km spatial resolution for 1951-2100. Statistically downscaled ensembles are based on output from twenty-four Coupled Model Intercomparison Project Phase 5...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Greenhouse gas emissions from large facilities indicator reports total emissions of large greenhouse gas emitters in...

CANGRD is a set of Canadian gridded annual, seasonal, and monthly temperature and precipitation anomalies, which were interpolated from stations in the Adjusted and Homogenized Canadian Climate Data (AHCCD); it is used to produce the Climate Trends and Variations Bulletin (CTVB).

Statistically downscaled multi-model ensembles of minimum temperature are available at a 10km spatial resolution for 1951-2100. Statistically downscaled ensembles are based on output from twenty-four Coupled Model Intercomparison Project Phase 5 (CMIP5) global climate models (GCM). Daily minimum...

Statistically downscaled multi-model ensembles of projected change (also known as anomalies) in minimum temperature (°C) are available at a 10km spatial resolution for 1951-2100. Statistically downscaled ensembles are based on output from twenty-four Coupled Model Intercomparison Project Phase 5...

Statistically downscaled multi-model ensembles of projected change (also known as anomalies) in total precipitation are available at a 10km spatial resolution for 1951-2100. Statistically downscaled ensembles are based on output from twenty-four Coupled Model Intercomparison Project Phase 5...

Seasonal and annual trends of mean surface air temperature change (degrees Celsius) for 1948-2016 based on Canadian gridded data (CANGRD) are available at a 50km resolution across Canada. Temperature trends represent the departure from a mean reference period (1961-1990). CANGRD data are...

Long-term freshwater quality monitoring data for over eight sites in the Ottawa River basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada...

Water temperature data were collected by Environment and Climate Change Canada at selected locations in Lake Winnipeg.Thermograph moorings were deployed in the north basin at station 505 and 506, in the south basin at station 500, in the Lake Winnipeg Narrows at station 502, northwest of Berens...

Provides public access to real-time instantatenous streamflow collected at over 1800 active locations in Canada. These data are collected under a national program jointly administered under federal-provincial and federal-territorial cost-sharing agreements; 2. Provides public access to archived...

Environment and Climate Change Canada added 40 compact stations, 10 ATMOS stations and 3 standard automated MSC Auto8 stations to the existing networks to form a high-resolution monitoring system across southern Ontario known as the Mesonet. These stations provided both high-density spacing and...

This application generates ice coverage bar graphs and data tables for the selected region and given dates.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada’s performance on key environmental sustainability issues. The data collection contains datasets that track water quality within Canada. The Water quality in Canadian rivers indicators...

The Canadian Environmental Sustainability Indicators CESI program provides data and information to track Canada's performance on key environmental sustainability issues. The Air Pollutant Emissions indicators track the total emissions of key air pollutants from anthropogenic human-related...

The radar network consists of 31 weather radars spanning Canada's most populated regions, providing coverage to over 95% of the population. The network's primary purpose is the early detection of developing thunderstorms and high impact weather.

Pollution Prevention (P2) Planning Notices published in the Canada Gazette under the Canadian Environmental Protection Act, 1999 (CEPA) legally require persons subject to the Notice to prepare and implement a pollution prevention plan in respect of a specified substance(s). Environment and...

This spatial file includes the polygon boundaries of the four Pacific Great Blue Heron Conservation Regions in British Columbia, as described in the management plan. These Conservation Regions are recognized based on degree of isolation, population sizes, and differences in trends and threats....

Fathead minnow (Pimephales promelas) embryos and larvae are frequently used in toxicology, including short-term embryo-only tests which often use small volumes of test solution. The effect that such conditions may have on Fathead minnow development has yet to be explicitly described. Here we...
