18 years of the warm season snow/ice presence over Canada and neighboring regions at 250m spatial resolution

Trichtchenko, Alexander (NRCan/RNCan)

The time series (18 years) of the warm season (April-September) probabilities of snow/ice presence derived from MODIS sensor at the Canada Centre for Remote Sensing (CCRS) are available from the Canadian Federal Geospatial Platform (FGP) data archive. They have been produced for each warm season for the 2000-2017 period.  The products are generated at the 250m spatial grid, which provides a good compromise for joint snow and land ice mapping.  The maps are provided as a binary raster image of the size 22800 pixels by 19200 lines. Data are produced in the Lambert Conformal Conic (LCC) projection over the Northern latitudes that cover Canada and neighboring regions. The Minimum Snow/Ice (MSI) extent derived from these maps demonstrate interannual consistency and good agreement with the Randolph Glacier Inventory (RGI) results.  The MSI data can be recommended for the RGI validation and updates, as well for various other studies related to climate of high latitudes and alpine regions of North America.

The data products, format description and other relevant information are available at
