Anomalous snow is also located at the edge of clouds, and in other areas in the interiors of continents. Some of that spurious snow is due to mapping snow in shallow lakes that are not on the land-water mask. Sea ice extent determined from ice surface temperature and from surface reflectance will be evaluated, however. Level 2 sea ice products just being released. Limited announcement of product availability has been done so far.
Web pages are available and evolving.
Thinking about local caches containing polar subsets of snow and ice products. Much higher ingest rates are now reality. Additional validation of the products is needed. Convenient for acquiring single scenes, but cumbersome for many. Steep learning curve.
