Locations of active electronic weather stations maintained by the Ministry of Transportation to support Avalanche and Winter Road maintenance operations.

This dataset contains district boundaries representing geographic areas of operational responsibility within Parks Operations Division, Alberta Environment and Protected Areas. Parks Operations Division Districts nest within Parks Operations Division Management Areas, which are areas of managerial responsibility within Parks Operations Division. Management Areas in turn nest within Parks Operations Division Regions. These boundaries are administrative/operational in nature, and are subject to change.

Weather stations operated by Manitoba Agriculture.Manitoba Agriculture operates a network of over 100 weather stations across Manitoba's agricultural region which provide hourly updated air temperature, relative humidity, precipitation, wind speed and direction, soil temperature and soil moisture. The WeatherStations feature class displays the location of the weather stations and its table contains a link to current weather for each station. Fields included: Weather Stations (StnName) Weather station name Latitude (LatDD) Latitude in decimal degrees Longitude (LongDD) Longitude in decimal degrees Elevation (m) (Elevation) Elevation in metres above sea level AgRegion Local geographic region for agriculture management in Manitoba More information (URL) Website link to information sheet on this location

This dataset contains boundaries of Management Areas, which are geographic areas of managerial responsibility within Parks Operations Division, Alberta Environment and Protected Areas. Management Areas are groupings of Districts, which are geographic areas of operational responsibility within Parks Operations Division. Parks Operations Division Districts nest within Management Areas, which in turn nest within Regions. These boundaries are administrative/operational in nature, and are subject to change.

**PLEASE NOTE:** The Environmental Monitoring System will be replaced by the EnMoDS system on March 5th, 2026. The EMS results objects will not contain new data after Feb 26th, 2026. For recent data please refer to [EnMoDS spatial locations and location groups](https://catalogue.data.gov.bc.ca/dataset/f60fa4b5-e3d0-44ad-b5d8-778d29764e34). Environmental Monitoring Stations (EMS) spatial points coverage for the Province by LOCATION TYPES. The following spatial layers reference this as a data source: 1. Environmental Monitoring - All Stations 2. Environmental Monitoring Stations - Air Monitoring (Ambient Air Site) 3. Environmental Monitoring Stations - Air Monitoring (Air Permit) 4. Environmental Monitoring Stations - Water Sites (Water Monitoring) 5. Environmental Monitoring Stations - Water Sites (Water Permits) 6. Environmental Monitoring Stations - Water Sites (Well) 7. Environmental Monitoring Stations - Water Sites (Observation Well) 8. Environmental Monitoring Stations - Water Sites (Spring)

The Fieldnotes dataset represents the anticipated locations of DFO Science field operations for 2020-2021 in the North Pacific and Arctic oceans, as well as in the coastal and interior waters of British Columbia and the Yukon.

644 datasets of Typical Meteorological Years (TMY) created by joining twelve Typical Meteorological Months selected from a database of up to 20 years of CWEEDS hourly data. The months are chosen by statistically comparing individual monthly means with long-term monthly means for daily total global solar irradiance, mean, minimum and maximum dry bulb temperature, mean, minimum and maximum dew point temperature, and mean and maximum wind speed. These hourly datasets are used by the engineering and scientific community mainly as inputs for solar system design and analysis and building energy systems analysis tools. This dataset has been updated with the most recent changes made in March 2023. The solar values in these files are based on 0.1° x 0.1° (11 km x 11 km grid) for all of Canada. Refer to Data Resources below for additional information on the TMY file format.

Assess the importance of atmospheric deposition of contaminants as a contributor to ecological impacts of oil sands development and identify sources. • Use snowpack measurements sampled across a gridwork to develop maps of winter-time atmospheric contaminant loadings for the region ~100 km from the major upgrading facilities • Assess long-term trends in winter-time atmospheric deposition • Determine the potential impact of wintertime snowpack mercury loads on tributary river water mercury concentrations (Spring Freshet) using Geographic Information System and hydrological modelling approaches • Compare snowpack loadings to those obtained from precipitation monitoring and compare spatial patterns to PAC air measurements obtained from passive sampling networkAll data are subjects of a publication containing method details, full QA/QC, interpretations and conclusions.
