Snowfall water equivalent projections derived uisng the statistically downscaled climate scenarios from CMIP6 global climate models (CanDCS-M6)

To help address the growing demand for snow information in a changing climate, the Canadian Centre for Climate Services (CCCS) has produced projections of daily water equivalent of snowfall and rainfall. This product is derived from the Multivariate Canadian Downscaled Climate Scenarios for CMIP6 (CanDCS-M6) dataset, produced by the Pacific Climate Impacts Consortium (PCIC). These datasets are available for a multi-model ensemble of 26 CMIP6 GCMs under 4 Shared Socioeconomic Pathways (SSPs): SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5). Additional details on the CanDCS-M6 ensemble and its downscaling methodologies are documented in Sobie et al. (2024).

Snowfall water equivalent (formally known as the Height of New snowfall Water equivalent, HNW, but is more commonly abbreviated as SWE) is estimated using a solid/liquid precipitation fraction partitioning scheme described in Dai (2008) and Sobie & Murdock (2022). The solid precipitation fraction is first estimated by applying a hyperbolic tangent function to daily mean temperature outputs and then scaled between -10°C and 10°C. The fraction is then applied to total precipitation outputs to obtain snowfall water equivalent values. Subsequent rainfall values are computed as the difference between total precipitation and the snowfall water equivalent.

A number of climate indices are also derived using each daily variable. For snowfall: total snowfall (prsntot), max 1-day snowfall (snx1day), number of days when snowfall exceeds 2 and 10 mm (sn2mm & sn10mm), first day when snowfall exceeds 1mm, last day when snowfall exceeds 1mm, and the snowfall season length are available. For rainfall, total rainfall and max 1-day rainfall are available. 

The indices are available across Canada at 10km grid spatial resolution from 1950-2100. They include climate indices for annual, seasonal, and monthly time frequencies. Outputs for individual models, ensemble statistics, and 30-year averages and changes are also available.

The CCCS would also like to acknowledge and thank PCIC for independently developing and verifying some of the snowfall water equivalent climate indices, sharing their methodologies, and providing their data for the validation of these indices.

Lethal and sublethal toxicity of ytterbium (Yb) in rainbow trout juveniles

The heavy rare earth element ytterbium (Yb) is a critical element of technology finding its way into urban wastewaters from solid waste disposal sites. The purpose of this study was to investigate the lethal and sublethal toxicity of Yb to rainbow trout juveniles. They were exposed to increasing concentrations of Yb3+ (0.06–40mg/L) for 96 hours (h) at 15 degrees Celsius (°C). Mortality was recorded, and in the surviving fish, the following biomarkers were determined: protein aggregation, thioneins, lipid peroxidation (LPO), and DNA damage in gills and the liver. The 96-h lethal concentration (LC50) was 2.7 ± 0.66 mg/L indicating that this element is toxic to fish. Biomarker responses to Yb occurred at concentration 45 times less than the LC50 in some cases. The following biomarkers were positively (p < 0.05) correlated to fish survival: liver thioneins, gill DNA strand breaks, LPO, and protein aggregation in the liver. The decrease in LPO in the liver and gills by Yb suggests reduced production of reactive oxygen species production. In conclusion, Yb is toxic to trout juveniles producing sublethal effects at concentrations range of 60 μg/L after 96 h. This concentration represents an upper limit for consideration for aquatic animal health.

Supplemental Information


The Chemicals Management Plan (CMP) is a Government of Canada initiative aimed at reducing the risks posed by chemicals to Canadians and their environment. A key element of the Chemicals Management Plan is the monitoring and surveillance of levels of harmful chemicals in Canadians and their environment. Monitoring and surveillance are essential to identify and track exposure to hazards in the environment and associated health implications. Monitoring and surveillance programs provide the basis for making sound and effective public health and environmental health policies and interventions, as well as measuring the efficacy of control measures. 


In support of the Chemicals Management Plan, monitoring and surveillance initiatives were established to support Health Canada and Environment and Climate Change Canada scientists, in collaboration with external partners and researchers, to advance our knowledge. This initiative has allowed the Government of Canada to increase its commitment to a number of existing monitoring initiatives, as well as to support new efforts.

Canadian Total Diet Study - Polychlorinated biphenyls (PCBs) 1992-2015

Polychlorinated biphenyls (PCBs) are a class of industrial chemicals that were used in a wide variety of applications including transformer oils, paints, and lubricants. PCBs are lipophilic compounds and accumulate in the tissues of biological organisms and bioconcentrate through the food chain. These compounds are thermally stable, persist in the environment and are subject to long-range transport. Canadian regulations related to PCBs came into force in 2008, which limit the release of these chemicals to the environment. PCBs can still be detected at very low levels in the Canadian food supply, particularly higher fat foods of animal origin.
