Maybe someone can show sentinels of this CAB scene:
PolarView is well organized, first mouse over your Worldview feature to get accurate lat, lon; then mouse over PolarView to get the right tile, then mouse over the date line to get more dates. The resolution is fabulous. Sentinel-1AB won't go very far back however.

Why so many mumbo-jumbo posts about snow cover? Some folks are confusing the Northern Hemisphere (half the planet) with the Arctic Ocean (a cold desert seasonally covered with floating ice occupying ten percent of the planet's oceans). Snow on permafrost, NH snow anomaly sites, 2m lake effect snowstorms in Buffalo NY (resp. home town anecdote), Arctic snow pack residuals 6 months from now?
Wrong forum. This is the Arctic sea ice freezing season forum. Neven will start an Arctic melt season forum when that becomes appropriate.
Actual daily data specific to the Arctic Ocean shows
ankle-deep snow at best over almost the entire Arctic Ocean today, yesterday, the whole season (graphic below, open source data RASM-ESRL_4UAF_ICE_2018-02-25).
People here have been struggling with that: "Buffalo NY is not even half-way to the pole, it gets tons of snow, the Arctic Ocean is much farther north, it follows the Arctic Ocean has a vastly deeper snow cover than Buffalo NY". It doesn't. It has vastly less.
Ankle-deep is a stand-in for 100 mm (0.1 m, 3.9 inches). Ankle-deep is much less than knee-deep or waist-deep. Google has pictures for those words if they are unfamiliar. Would you snow-camp in ankle-deep snow, using it for a thermal blanket? It accomplishes nothing to post away here wishing/assuming/claiming the Arctic Ocean snow is deeper. It is not.
That same site has daily radiative energy fluxes, up and down. Numbers for each location. Why share vague feelings about generic clouds and possible snow six month out? Look at their watts/m
2 and spare us flux intuiting.
Clouds and snow are highly variable and very complex so can't be intuited, that's why universities have physics depts, that's why we put sampling teams and radiometers out on the ice. Maybe you have an unannounced Nobel Prize in physics? After assimilating flux numbers from the scientific community, sure, post away if you have something better (
include a working url and why you think it is better).
