Manual snow survey (active & inactive) locations as part of the BC Snow Survey program.

Snow survey administrative basin areas, which are components of the BC snow survey network. Basin codes are used as basis of snow survey station names, and for some reporting purposes.

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

Monthly snow cover extent (SCE) for Arctic land areas (>60° N) for (a) May and (b) June 1967–2020, a 54-year record. Anomalies are relative to the 1981–2010 average and standardised (each observation was differenced from the mean and divided by the standard deviation, and thus unitless). Solid black and red lines depict 5-year running means for North America and Eurasia, respectively. Filled circles are used to highlight 2020 anomalies. (Mudryk et al. 2020).

The Ministry of Transportation and Infrastructure's Avalanche and Weather Programs is responsible for the support and maintenance of the ministry's weather data. While reasonable care is exercised in recording and communicating accurate data, the province neither warrants nor represents the sufficiency of this information.

The Copernicus Wet/Dry Snow (WDS) product is generated in near real-time for the entire EEA38 and the United Kingdom, based on radar satellite data from the Sentinel-1 constellation. The product differentiates the snow state conditions within the snow mask defined by the FSCTOC information (snow fraction at the top of canopy - see the Copernicus Fractional Snow Cover product) with a spatial resolution of 60 m x 60 m. In other words, it provides a binary discrimination of wet and dry snow, identifying patchy snow or snow free areas. The WDS product is distributed in raster files covering an area of 110 km by 110 km with a pixel size of 60 m by 60 m in UTM/WGS84 projection, which corresponds to the Sentinel-2 input L1C product tile. Each product is composed of two separate GeoTIFF files corresponding to the different layers of the product (the snow state classification -SSC- and the associated quality layer -QCSSC-) and a metadata file. The WDS is one of the products of the pan-European High-Resolution Snow & Ice service (HR-S&I), which are provided at high spatial resolution (20 m x 20 m and 60 m x 60 m), from the Sentinel-2 and Sentinel-1 constellations data from September 1, 2016 onwards.

This dataset contains location information for 2 of Ontario’s snow monitoring networks: * Surface Water Monitoring Centre (SWMC) * Snow Network for Ontario Wildlife (SNOW), administered by the Wildlife Research and Monitoring Section Snow course data is collected by: * conservation authorities * Ministry of Natural Resources (MNR) districts * Ontario Power Generation SWMC network data is collected twice a month from November 15 until May 15. SNOW network data is collected once a week from the first snowfall until snowmelt. The Surface Water Monitoring Centre uses the data to assess: * current snow cover * frozen ground conditions * snowpack * potential snowmelt * contributions to streamflow MNR’s Science and Research Branch use the data to: * help manage wildlife species including deer, moose, wild turkey, elk, wolves and coyotes * help ministry resource managers and scientists administer programs and conduct research * inform game management decisions such as white-tailed deer harvest quotas * support flight planning for the Moose Aerial Inventory program

The Surface Water Monitoring Centre uses this data to assess: * current snow cover * frozen ground conditions * snowpack * potential snowmelt * contributions to streamflow The snow data is located in a corporate water and climate database. This data helps MNR and conservation authorities assess the potential for flood at the local and provincial scale.

The Copernicus Persistent Snow Area (PSA) product is generated annually for the entire EEA38 and the United Kingdom, based on the Fractional Snow Cover (FSC) information. It provides the extent of the persistent snow cover, i.e. the area where snow is present throughout the hydrological year with a spatial resolution of 20 m x 20 m. This metadata refers to the PSA product distributed in raster files as tiles aligned with Sentinel-2 (UTM/WGS84) at 20 m x 20 m GSD. It is also available in another projection as tiles aligned with the Pan-European High-Resolution Layers in the European 20 m x 20 m grid (ETRS89 LAEA - EPSG: 3035). It is typically released on an annual basis with a release date in October, after the end of the hydrological year. Each product is composed of two separate files corresponding to the different layers of the product, and another metadata file. PSA is one of the products of the pan-European High-Resolution Snow & Ice service (HR-S&I), which are provided at high spatial resolution (20 m x 20 m and 60 m x 60 m), from the Sentinel-2 and Sentinel-1 constellations data from September 1, 2016 onwards.

A wide range of different territorial, federal, and first nation governments have a role in monitoring water. The water monitoring sites data set compiles these varied sources into a single source with the intent to provide a 'one-stop shop' when searching for water monitoring data. Information contained includes the 'who, what, when, and where' of water monitoring by providing contact information, sample type, sample period, and location. Distributed from GeoYukon by the Government of Yukon . Discover more digital map data and interactive maps from Yukon's digital map data collection. For more information: geomatics.help@yukon.ca
