The Native Prairie Vegetation Inventory (NPVI) Polygons is a quarter section-based vegetation inventory that covers the southern part of Alberta. The native prairie is defined in the Native Prairie Conservation Action Plan as an area of unbroken grassland or parkland dominated by non-introduced species, and an area of previously broken grassland that has reverted back to natural vegetation (30 to 60 years). The Native Prairie Vegetation Inventory extends beyond the Grasslands Natural Region to include data for adjacent areas, such as the Cypress Hills. In addition to the Grassland Natural Region, the Native Prairie Vegetation Inventory (NPVI) Polygons include areas that belong to the Foothills Parkland, Central Parkland, Montane, Dry Mixedwood Boreal and Lower Foothills Natural Subregions.

The Town dataset is comprised of all the polygons that represent Towns in Alberta. Town is a municipality type defined under the authority of the Municipal Government Act. The formation of a Town can occur if a majority of buildings are on parcels of land smaller than 1850 square metres and there is a population of 1000 or more.

The Village dataset is comprised of all the polygons that represent Villages in Alberta. Village is a municipality type defined under the authority of the Municipal Government Act. The formation of a Village can occur when a majority of the buildings are on parcels of land smaller than 1850 square meters and there is a population of 300 or more.

Regional Deterministic Air Quality Analysis (RDAQA) is an objective analysis of surface pollutants that combines numerical forecasts from the Regional Air Quality Deterministic Prediction System (RAQDPS) with hourly observations from various monitoring networks in North America, including the Canadian measurement networks operated by the provinces, territories and certain cities, as well as the various American networks in the context of the AIRNow program administered by US/EPA (US Environmental Protection Agency). RDAQA analysis provides the best description of current air quality conditions, and is used to inform the public, meteorologists in the various Environment and Climate Change Canada forecasting offices, Health Canada and other users about the distribution of air pollutants near the ground, and the performance of forecasting models. Each hour, a preliminary product is available approximately one hour after the observation measurement time, while final and Firework products are available approximately two hours after the measurement time. The preliminary and final products contain analysis of the chemical constituents O3, SO2, NO, NO2, PM2.5 (fine particles with diameters of 2.5 micrometers or less) and PM10 (coarse particles with diameters of 10 micrometers or less), while the Firework product contains analysis of PM2.5 and PM10.

The City dataset is comprised of all the polygons that represent Cities in Alberta. City is a municipality type defined under the authority of the Municipal Government Act. The formation of a City can occur when a majority of the buildings are on parcels of land smaller than 1850 square meters and there is a population of 10 000 or more.

CMIST is a peer-reviewed screening-level risk assessment tool for marine invasive species (Drolet et al. 2016). It is a short questionnaire that follows the invasion process from arrival to impact and is designed so an informed assessor can evaluate one species in an assessment area in approximately one day using easily accessible information from internet databases, primary literature, and grey literature. Species can be those with an invasion history in an area or those that are candidates for future invasions.CMIST is score-based and incorporates both likelihood and impact of invasion as well as uncertainty. Questions are general to make CMIST broadly applicable to different taxa, different assessment areas, and different project goals. To date, CMIST has been tested with molluscs, tunicates, crustaceans, and polychaetes introduced or at risk of introduction to three Canadian marine ecoregions (DFO 2009). CMIST has also been successfully applied to non-indigenous freshwater fish in British Columbia with adapted guidelines (T. Therriault, pers. comm.). Upon completion, CMIST produces a risk score adjusted for the assessor’s uncertainty which, combined with information collected during the assessment, can be used to assist in management decisions. For example, in 2015, CMIST assessments were used to identify high risk invaders in three Canadian marine ecoregions (DFO 2016).

Crop Heat Units (CHU) are calculated on a daily basis, using the maximum and minimum temperatures in order to account for a crop’s negative response to higher temperatures.The formula used to calculate the CHU value for a day is: (1.8 × (Minimum Temperature − 4.4) + 3.33 × (Maximum Temperature − 10) − 0.084 × (Maximum Temperature − 10)²) ÷ 2.0CHU values are only accumulated during the Growing Season, April 1 through October 31.

The Ministry of Environment operates a network of continuous ambient air monitoring stations to measure the concentration of air pollutants across Saskatchewan. This is considered 'raw data' that has not undergone quality control and quality assurance. 'Raw data' is not intended to provide medical or health care advice and should not be used in published documents. For best results download the entire dataset without filtering as a CSV. ‘Date and time’ as displayed is your local time. However, downloaded data is in UTC for ‘Date and time’. Any values of -9999, -999, or 9980 are invalid data.The Ministry of Environment operates a network of continuous ambient air monitoring stations. These stations are part of the National Air Pollution Surveillance (NAPS) network. Continuous ambient air monitoring stations measure the concentration of air pollutants across Saskatchewan. The data is used to:  • track and report on progress for achieving air quality objectives • measure representative pollutant concentrations and determine long-term trends and • provide air quality information to the public Air pollutants typically come from various industrial activity and natural sources, such as mining, oil and gas, agriculture, forest fires, electrical generation, and the transportation sector.

The Municipal District dataset is comprised of all the polygons that represent Municipal Districts in Alberta. Municipal District is a municipality type defined under the authority of the Municipal Government Act. The formation of a Municipal District occur when a majority of the buildings used as dwellings are on parcels of land with an area of at least 1850 square meters and there is a population of 1000 or more. A municipal district is a government form in rural areas of the province.

The Inuit Regions, also known as the Inuit Nunangat, dataset contains the geographical boundaries of the 4 Inuit Regions in Canada: Inuvialuit, Nunavut, Nunavik and Nunatsiavut. The boundaries, land only, have been drawn as per information defined in each land claim agreement. The Inuit Regions (Inuit Nunangat) geographical boundaries are approximate and should be used for illustration purposes only.This dataset is Crown-Indigenous Relations and Northern Affairs Canada (CIRNAC) and Indigenous Services Canada (ISC) official source for Inuit regions on maps.
