In 2016 NETCARE scientists conducted two measurement campaigns at the Dr. Neil Trivett Global Atmosphere Watch Observatory (the “Alert Observatory”) on the northeastern tip of Ellesmere Island in the Canadian Arctic (latitude: 82.5163, longitude: -62.3085). The first campaign...

A large-scale aircraft campaign (on the German POLAR6 aircraft) took place in July 2014, based out of Resolute Bay, Nunavut, aimed to assess the different roles that oceanic input and long range transport from lower latitudes play in driving Arctic atmospheric composition. For five days in late...

Monitoring of sea ice dynamics is of vital importance to our overall understanding of how the Arctic cryosphere is responding to changes in the Earth's climate. With the recent launch of the RADARSAT Constellation Mission (RCM) in 2019 and the continuing operation of the Sentinel-1 (S1) fleet,...

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...

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 indicators show the yearly and seasonal surface air temperature departures for the years...

Precipitation measurements in the Environment and Climate Change Canada (ECCC) surface network are a necessary component for monitoring weather and climate and are required for flood and water resource forecasting, numerical weather prediction and many other applications that impact the health...

The CanESM2 large ensembles are 50-member perturbed initial condition ensembles from 1950 to 2020, with all historical forcings (historical), solar and volcanic forcings only (historicalNat), anthropogenic aerosols only (historicalMisc, p4), and ozone only (historicalMisc, p6). The model,...

The Climate Research Division's climate modelling program provides climate model output for the climate science and climate change research community, nationally and internationally. This dataset includes global Earth System model output (from several generations of models), regional climate...

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...

The recent (2017) spatial patterns of zooplankton communities in 73 Québec lakes distributed over an 800-km SW-NE gradient, spanning a wide range of water quality and climate. Results were published in a scientific article that can be found here: https://doi.org/10.1139/cjfas-2020-0139

This dataset is part of the International Atomic Energy Agency (IAEA) Global Network of Isotopes in Precipitation (GNIP) project and contains the total monthly precipitation quantity in millimeters collected on the roof of the National Hydrology Research Centre in Saskatoon, SK and its stable...

This dataset consists of CLASS (Canadian Land Surface Scheme) simulations for ALMIP2 (AMMA [African Monsoon Multidisciplinary Analysis] Land Surface Model Intercomparison Project, Phase 2). The results of the intercomparison is published in the paper "Streamflows over a West African Basin from...

The Canadian Centre for Climate Modelling and Analysis (CCCma) Earth System Grid Federation (ESGF) Dataset provides the Environment and Climate Change Canada (ECCC) node on an internationally-coordinated system of climate model data dissemination developed specifically for the World Climate...

The data consists of temperature indices based on homogenized daily maximum and minimum temperatures at 338 locations across Canada, and of precipitation indices based on adjusted daily rainfall, daily snowfall and daily precipitation amounts at 463 locations across the country. These indices...

The data consist of homogenized daily maximum, minimum and mean surface air temperatures for more than 330 locations in Canada; adjusted daily rainfall, snowfall and total precipitation for more than 460 locations. The data are given for the entire period of observation. Please refer to the...

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...

Persistent, large-area droughts are among Canada’s costliest natural disasters, having major impacts on sectors such as agriculture, industry, forestry, recreation, human health and society, and ecosystems. This dataset provides 50 km gridded, 12-month Standardized Precipitation...
