Snow cover plays a critical role in the hydrological cycle of British Columbia and has widespread influence on, for example, drought, wildfires, ecology, and flooding. Operationally, snow is monitored using manual snow surveys and automated snow weather stations at specific locations throughout British Columbia (Province of British Columbia 2020); however, there are large spatial gaps in monitoring snow cover between these sparse point observations, particularly at high elevations and northern latitudes (Figure 1). The use of satellite remote sensing imagery provides an opportunity to monitor snow cover at a variety of spatial resolutions over time across British Columbia. This can improve our understanding of snow cover timing in British Columbia and allows for near-real-time snow cover maps to be generated, both of which are of great interest to research and operational hydrology.
