I'm looking for a freely accessible website that provides access to recent high-resolution (<~1–5 km) satellite-based snowcover estimates (snow / no-snow). Many meteorology websites provide an interface to cloud cover satellite imagery, but it's not always easy to see snow-cover from those.
The MODIS satellite provides visible imagery down to a 250-metre resolution. This can (in absence of clouds) certainly be used for the above-stated purpose, and indeed they produce a daily global snow-product at a roughy 5 km grid. Although accessible in principle in HDF-5 format, it's quite a bit of work to download and read this data to see the extent of snowcover 50 km from home.
The Senorge website provides a fantastic interface, exactly what I'm looking for, but only for Norway.
Many meteorological websites, e.g. SMHI in Sweden, provide regular snow-thickness maps, but those are heavily interpolated and irregularly updated.
Does anyone know a website that lets the user look at recent satellite-based snow products on an easily zoomable map? I'm most interested in Sweden at the moment, but it would be quite interesting if it was global (like the MODIS product).
