Global satellite snow cover map

Q: What is the Snow Cover layer on SnowWatcher?

Snow Cover is observed satellite snow cover from the Copernicus Global Snow Cover Extent (1 km) product via the Copernicus Data Space Ecosystem / Sentinel Hub. It shows where snow is present on the ground, not how many centimetres fell recently.

Q: Is satellite snow cover the same as snowfall?

No. Satellite snow cover is observed extent on the landscape. Resort snowfall cards on the same page use Open-Meteo weather-model snowfall (24h and 7-day), snow depth, and temperature so you can compare model snowfall with observed cover.

Q: How often is global snow cover updated?

SnowWatcher loads the latest available Copernicus observation for the Global Snow Cover Extent product. Observations are typically about a day old, depending on satellite processing. Resort snowfall cards refresh on a separate cached Open-Meteo schedule.

Q: Can I see snow cover for the Alps and other ski regions?

Yes. Open Global Conditions, tap Snow Cover to overlay satellite snow worldwide, then zoom to the Alps, Scandinavia, North America, Japan, or any ski region and filter resorts by country, 24h snowfall, or 7-day forecast.

Turn on Snow Cover for observed Copernicus satellite snow across the planet, then filter 570+ ski resorts by 24h snowfall, 7-day forecast, and snow depth.
