The Weather Stations dataset is derived from the Regional Weather Information System (RWIS). For more information about each weather station, refer to [https://rwis.gov.yk.ca/stations/](https://rwis.gov.yk.ca/stations/) . Currently only weather stations owned by Yukon Wildland Fire Management, Park s Canada, Environment and Yukon Avalanche Association are included in this dataset. Other weather stations will be added as they become available.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Locations of automated snow weather stations, active and inactive. Automated snow weather stations are components of the BC snow survey network.

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

Climate observations are derived from two sources of data. The first are Daily Climate Stations producing one or two observations per day of temperature, precipitation. The second are hourly stations that typically produce more weather elements e.g. wind or snow on ground.

Daily climate observations are derived from two sources of data. The first are Daily Climate Stations producing one or two observations per day of temperature, precipitation. The second are hourly stations that typically produce more weather elements e.g. wind or snow on ground. Only a subset of the total stations is shown due to size limitations. The criteria for station selection are listed as below. The priorities for inclusion are as follows: (1) Station is currently operational, (2) Stations with long periods of record, (3) Stations that are co-located with the categories above and supplement the period of record.

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

Point locations of water and weather monitoring stations used by the [Surface Water Monitoring Centre](http://www.ontario.ca/page/surface-water-monitoring-centre) to assess flood and drought conditions across Ontario. Monitoring station types include: * streamflow gauge stations * Environment and Climate Change Canada climate stations * Ministry of Transportation road weather stations * Ministry of Natural Resources (MNR) fire weather stations * MNR snow network stations (wildlife) * MNR snow survey stations (weather) * Ontario Power Generation snow survey stations (weather)

A Virtual Climate station is the result of threading together climate data from proximate current and historical stations to construct a long term threaded data set. For the purpose of identifying and tabulating daily extremes of record for temperature, precipitation and snowfall, the Meteorological Service of Canada has threaded or put together data from closely related stations to compile a long time series of data for about 750 locations in Canada to monitor for record-breaking weather. The length of the time series of virtual stations is often greater than 100 years. A Virtual Climate station is always named for an “Area” rather than a point, e.g. Winnipeg Area, to indicate that the data are drawn from that area (within a 20km radius from the urban center) rather than a single precise location.

Canadian hourly climate data are available for public access from the ECCC/MSC's National Climate Archive. These are surface weather stations that produce hourly meteorological observations, taken each hour of the day. Only a subset of the total stations found on Environment and Climate Change Canada’s Historical Climate Data Page is shown due to size limitations.The priorities for inclusion are as follows: stations in cities with populations of 10000+, stations that are Regional Basic Climatological Network status and stations with 30+ years of data.

Monthly, seasonal and annual trends of daily minimum, mean and maximum surface air temperature change (degrees Celsius) based on homogenized station data (AHCCD) are available. Trends are calculated using the Theil-Sen method using the station’s full period of available data. The availability of temperature trends will vary by station; if more than 5 consecutive years are missing data or more than 10% of the data within the time series is missing, a trend was not calculated.
