Snow Products

One of the components of WRMD’s snow service is satellite-based snow products. The products allow WRMD to monitor the extent of snow cover (SE) and the snow water equivalent (SWE). The SE and SWE imagery, acquired from GlobSnow and NASA, are processed regularly during the winter and the spring snowmelt period. GlobSnow SE and SWE imagery are available at www.globsnow.info opens new window, the NASA SE imagery is available at ladsweb.nascom.nasa.gov opens new window, and the NASA SWE imagery is available at wist.echo.nasa.gov/api opens new window.

Through advanced algorithms, WRMD processes the satellite-based imagery to create SE and SWE products for the Humber and the Exploits Basins. As the SE products are based on an optical satellite, cloud cover affects the adequacy of the images, and the SE products can only be created for cloud-free days. Additionally, the satellites obtaining the SE imagery do not provide coverage for the basins every day. The SWE products are currently being evaluated and will be made available afterwards.

The snow products for the Upper and Lower Humber River Basin and the Exploits River Basin are provided in the following table.
