This dataset corresponds to daily snow cover percentage at 1km resolution grid over land areas of Canada from 2006-2010. The data are subsampled by 4km to reduce data volumes and considering the geolocation uncertainty of the input satellite imagery. The daily maps are generated by assimilation of daily cloud screened NOAA AVHRR satellite imagery and Canadian Meteorological Centre (CMC) snow depth analysis snow depth and density fields within an off-line version of the CMC daily snow depth model. The snow depth model is modified to include snowpack reflectance model and a surface radiative transfer scheme that relates vegetation and snowpack reflectance to top-of-canopy bi-directional reflectance. A logistic vegetation phenology model is used to parameterize temporal dynamics of canopy leaf area index. A per-pixel particle filter with a 30 day moving window is applied to assimilation observations corresponding to 1km resolution visible band directional reflectance and normalized difference vegetation index and 24km CMC daily snow depth and monthly snow density fields. The assimilation is forced using daily air temperature and precipitation fields. Validation of the datasets has been performed by comparison to MODIS snow cover maps and in-situ snow depth stations across Canada. Validation suggests similar accuracy to MODIS snow cover products over relatively flat terrain. Validation over mountainous regions is ongoing.

Rideau Canal Skateway - Ice condition by section Each winter, the NCC transforms the historic Rideau Canal into the world’s largest skating rink. The Rideau Canal Skateway winds its way through the heart of the National Capital over a total length of 7.8 km. A UNESCO World Heritage Site, the Rideau Canal in winter becomes a treasure that is the pride of the National Capital and a signature destination. The skating season typically runs from January to early March, but it is weather-dependent. When open, the Skateway is free and accessible 7 days a week, 24 hours a day. When the Skateway is open, ice conditions are monitored by section twice daily, at approximately 8 am and 4 pm.

This polygonal dataset represents authorized applications for a Mines Act permit known as a Permitted Mine Area (PMA). This dataset can be used in combination with the NoW point dataset which represents both applications for a Mines Act permit and issued authorizations for mining activities proposed in the application. **The regional mine PMA dataset is not complete for all mine sites in BC. Review the data quality section for more information** Point representation of NoW: https://catalogue.data.gov.bc.ca/dataset/fab53209-63be-4c61-8de4-3e3fceec4227 Applications for regional Mines Act permits are known as Notice of Work (NoW) applications. Regional mine permits are issued for mineral and coal exploration activities, sand and gravel production, quarry production, and placer mining. Major mine permits are issued for producing mineral and coal mines. Permits are issued by the chief permitting officer under section 10 of the Mines Act and administered by the ministry. **Regional mines include:** * Exploration — mineral, coal, rock quarry, industrial mineral or dimension stone * Sand and gravel — aggregate, rock or natural substances used for construction purposes * Placer Most exploration and development activities require a permit under the Mines Act. A decision marks the end of the permitting process for a NoW application. The decision can either be to reject the application or to authorize the mining activities proposed in the NoW. * For new NoW authorizations, a Mines Act permit is issued * For an existing open Mines Act permit, the newly authorized mining activities are amended to the existing permit and the permit is re-issued Notice of Work categories include: Notice of Work application type, Notice of Work application status. **Notice of Work application type** Field: NOW_APPLICATION_TYPE_DESC (NW_APPTYPD) * Coal * Mineral * Placer Operations * Quarry – Construction Aggregate * Quarry – Industrial Mineral * Sand and Gravel **Notice of Work application status** Field: NOW_APPLICATION_STATUS_DESC (NW_APPSTAD) * Approved – mining activities in the NoW application have been authorized **For the public view, please be aware that the ministry:** * Removed the attribute value of closed permits in the PERMIT_STATUS_CODE_DESC (PMT_STD) field. These records will show as permit status is NULL (empty). * Only shows mine commodities of gold or jade/nephrite in the MINE_COMMODITY_DESC (MN_COMD) field. All other commodity values remain NULL (empty)

The probability (likelihood) of ice freeze days, the number of days in the forecast period with a minimum temperature below the frost temperature, -5°C for herbaceous crops over the non-growing season (ifd_herb_nogrow_prob). Week 1 and week 2 forecasted probability is available daily from November 1 to March 31. Week 3 and week 4 forecasted probability is available weekly (Thursday) from November 1 to March 31. Over-wintering crops are biennial and perennial field crops such as herbaceous plants (strawberry, alfalfa, timothy, and many other forage crops) and woody fruit trees (apple, pear, peach, cherry, plum, apricot, chestnut, pecan, grape, etc.). These crops normally grow and develop in the growing season and become dormant in the non-growing season. However, extreme weather and climate events such as cold waves in the growing season and ice freezing events during the winter are a major constraint for their success of production and survival in Canada. The winter survival of these plants depends largely on agrometeorological conditions from late autumn to early spring, especially ice-freezing damage during the winter season. The optimum temperature for such crops is 25°C. Agriculture and Agri-Food Canada (AAFC) and Environment and Climate Change Canada (ECCC) have together developed a suite of extreme agrometeorological indices based on four main categories of weather factors: temperature, precipitation, heat, and wind. The extreme weather indices are intended as short-term prediction tools and generated using ECCC’s medium range forecasts to create a weekly index product on a daily basis.

An accumulated value of heat degrees that the average temperature is above a specified threshold, 5°C for cool season crops. This condition must be maintained for at least 5 consecutive days in order for EGDD to be accumulated (egdd_cool). Week 1 and week 2 forecasted index is available daily from April 1 to October 31. Week 3 and week 4 forecasted index is available weekly (Thursday) from April 1 to October 31. Cumulative heat-energy satisfies the essential requirement of field crop growth and development towards a high yield and good quality of agricultural crop products.
