The Government of Canada's Fuel Life Cycle Assessment Model (the Model) is a tool to calculate the life cycle carbon intensity (CI) of fuels and energy sources used and produced in Canada. The Model is used to determine the CI of hydrogen for the purpose of creating tax credits under the Clean...

This study aimed to provide insights into how climate-driven diet shifts may impact contaminant exposures of Arctic species. We compared feeding ecology and contaminant concentrations in ringed seals (Pusa hispida) from two Canadian sub-Arctic (Nain and Arviat) and two Arctic sites (Sachs Harbour...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Temperature change in Canada indicator shows the yearly and seasonal surface air temperature departures for the years...

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...

This first version of the dataset (CanHoPmlyV1) contains homogenized time series of monthly total precipitation for 425 long-term stations in Canada. As detailed in Wang et al. (2023), it is based on the quality-controlled version 2020 of the Adjusted Daily Rainfall and Snowfall (AdjDlyRS)...

Black carbon is a short-lived, small aerosol (or airborne) particle linked to both climate warming and adverse health effects. It is emitted from incomplete combustion of carbon-based fuels (i.e., fossil fuels, biofuels, wood) in the form of very fine particulate matter. Black carbon is not...

The d4PDF-WaveHs dataset represents the first single model initial-condition large ensemble (SMILE, 100-member) of historical significant ocean wave height (Hs) at a global scale. It was produced using an advanced statistical model with predictors derived from Japan's database for policy...

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...

The Hudson Bay Lowlands (HBL) is the wettest ecozone in Canada with 80% of its area covered by wetlands. It forms the third largest wetland in the world and is composed almost entirely of permafrost and non-frozen subarctic peatlands that store more carbon in the first 2 m of soil than the total...

Climate warming and permafrost thaw induced land cover change are well documented in much of the circumpolar north. The frequent exposure of Precambrian continental crust in Canada’s Taiga Shield ecoregion could mean impacts of land cover change documented in other regions without this feature...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The indicator provides an overview of Canada's projected greenhouse gas (GHG) emissions up to 2035. The indicator allows the...

Since 2009, the Watershed Hydrology and Ecosystems Research Division of Environment and Climate Change Canada (ECCC) has coordinated spring time multi point ice thickness and composition surveys at up to 15 lake sites in the Northern Hemisphere. Data collected includes on ice snow depth, total...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Greenhouse gas concentrations indicator shows the trends in concentrations for 2 greenhouse gases: carbon dioxide (CO2)...

The Government of Canada’s Fuel Life Cycle Assessment (LCA) Model is a tool to calculate the life cycle carbon intensity (CI) of fuels and energy sources used and produced in Canada.

The AdjDlyRS dataset contains adjusted daily rainfall (R) and snowfall (S) data from all Canadian stations reporting rainfall and snowfall for which we have metadata to do the adjustments (Wang et al. 2017). The processing includes inspection and adjustments using quality control procedures...

Humidex (Masterton and Richardson 1979) is an index developed by the Meteorological Service of Canada to describe how hot and humid the weather feels to the average person. In Canada, it is recommended that outdoor activities be moderated when the humidex exceeds 30, and that all unnecessary...

Drought projections on seasonal to annual time scales are presented for Canada over the twenty-first century, based on the Standardized Precipitation Evapotranspiration Index (SPEI). Results make use of bias-corrected temperature and precipitation projections from 29 global climate models...

Multi-model ensembles for a suite of variables based on projections from Coupled Model Intercomparison Project Phase 6 (CMIP6) global climate models (GCMs) are available for 1850-2100 on a common 1x1 degree global grid. Climate projections vary across GCMs due to differences in the representation...

Continuous, year-round measurement of stream stage that is later converted to flow using a stage-discharge relationship occurs on at/near the lake outflows and 2 other stations along the principal watershed tributary, Norberg Creek. Measurements ended in 2016. Supplemental Information The Climate...

This dataset contains relative trends of annual and monthly regional maximum ocean wave heights in the Arctic, and data for three predictors derived from surface winds and sea ice concentration. It also contains estimates of historical (1979-2205) and future (2081-2100, RCP8.5 scenario) annual...
