Snow cover data at 20 m resolution with 5 day revisit time since 2015 (cloud permitting) over selected regions. The data are derived from Sentinel-2 (since 2015) and Landsat 8 (2013-2021).
Data access is currently split in two platforms:
- Near real time data after 2022: https://hydroweb.next.theia-land.fr/
- Archive (since 2013): https://geodes.cnes.fr/
The level 2B products provide the snow cover fraction by pixel and a cloud mask. The level 3B products provide multitemporal metrics of the annual snow « phenology » (see the gallery below). The product format is described here: https://gitlab.orfeo-toolbox.org/remote_modules/let-it-snow#products-format.
The Level 2B products are also available in near real time over the entire Europe from Copernicus Land: https://land.copernicus.eu/en/products/snow/fractional-snow-cover.
