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...

Weekly precipitation quantity has been measured at both at the primary meteorological site as well as at five other sites within the watershed. Daily precipitation quantity has been measured at the primary meteorological site until 2017. Weekly chemistry analysis of H+, major ions, nutrients and...

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...

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.

The Canada’s Changing Climate Report (www.changingclimate.ca/CCCR2019), led by Environment and Climate Change Canada, is about how and why Canada’s climate has changed and what changes are projected for the future. Datasets supporting the results produced for the Canada’s Changing Climate report...

High-resolution statistically downscaled climate indices relevant to climate change impacts in Canada are available at a 10 km spatial resolution and an annual temporal resolution for 1951-2100. The climate indices are based on model projections from 24 global climate models (GCMs) that...

This dataset was extracted from the 50-member Large-Ensemble Canadian Regional Climate Model (CanRCM4-LE) (Scinocca et al., 2015), North American region 0.44° horizontal grid resolution (NAM-44) model runs. Basin averaged means for nine river basins in Western Canada consisting of three...

The Alberta foothills are a primary source of spring runoff into the prairie regions to the east. For this reason, precipitation accumulations in the foothills are vital to prairie water resources. The Foothills Orographic Precipitation Experiment (FOPEX) was initiated in 2002 to study the...

NAV CANADA (NC) provided Environment and Climate Change Canada (ECCC) with automated minutely weather observations from six select AWOS stations (i.e. airport locations) in southern Ontario as an experimental, proof-of-concept program in support of the 2015 Games. The minutely data were at a...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Precipitation change in Canada indicator measures the annual and seasonal precipitation departures (or anomalies) for the...
