A beautiful example of how you can spot fresh snow via M10 Band.

The location is between Greenland and Svalbard. 20 frames. Click to play.
It also tells us something about the existing snowpack not being being fresh, and having potentially seen *some* above freezing temps.

Lots of clouds over the ESS, but glimpses show a little fresh snow in areas, but it appears to me that much of the existing snowcover isn't all that impressive.

Band M8. Needs click

VIIRS band M8 indicating a change in snow characteristics stretching from just north of Wrangel Island to Banks island.  It occurs just south of a storm track so my feeling is that's it's due to precipitation.  It coincides with the AMSR2 concentration data from Bremen. Second attachment.
Click to run. Contrast boosted for detail.

Shot centered a roughly 68°N, 154°E.   4 day change.  Kolyma river in the lower left can be seen thawing, might start spilling out the delta and onto the fast ice soon.  One can also see several "kettle ponds?" melting out, as well as some reduction in snowcover.

Just noticing now that the RAMMB added a bunch of awesome RGB composites after seeing some of blumenkraft's posts.

Beaufort is responding to easterly winds.  Should open up nicely over the next 3 days.
Band M8 showing quite varied snow quality, mostly not very fresh.  You can also see the warm surging up north, in the last frames.  Floes look pretty small, except maybe the ones near Banks island, and even those look a bit dodgy.
A short 10 loop, contrast boosted. Click to run.

Lena river outlet in the upper right.  These look like thunderstorms bubbling up and moving towards the arctic shores.  Three also a line of likely thunderstorms in my opinion, associated with a front moving across the Lena.  Hopefully we get some clearing afterward, and are able to see the discharge.

I sent an email to the RAMMB webmaster about imagery not updating the last 2-3 days, hopefully there's a response, or things start updating again.

I did find a neat blog post about the new RGB bands which gives some information about them.  The importance of band M8, which we figured out last season is discussed.

24 hour loop.  The big storm dropped little snow, some just to the North American side of the pole, and the Beaufort might have received a dusting.  Mostly rain however in my humble opinion.  One can see the cyclonic curvature of the rain bands in the latest AMSR2 microwave shot. 2nd attachment

Ah, and as far as the Snow/Ice band is concerned, this is all bloody water down there.

Today was the only day it was really clear enough, I'll make another tomorrow if it is clear again. I used band I2. Let me know if you want anything adjusted.

RAMMB-SLIDER not updating. This is the last snapshot.

It looks like a software problem that caused something to crashed to me.

IIRC it was the same last time it stopped updating but not 100% sure about that. Let's observe this. It could be useful information for the RAMMB developers.

Edit: The I bands are going until 22:11:10 UTC. Geo-Color goes until 17:06:46 UTC. hmmmm

Still not updating and my emails haven't been responded to.   Frustrating that it seems like like care is paid to the polar orbiting satellites.  Perhaps some other members could email the webmaster. Preferably someone with an email from a university orvthe like, as that might elicit a response.   
Thanks

Well, I give up.  I sent the last email I will to the RAMMB webmaster.  Is been two weeks of either none, or basically unusable imagery.  I'll make one last plea to anyone in the academic community to please reach out, and see if there's any plan to continue offering polar satellite imagery.  It's experimental, so there was never a guarantee that it would be maintained.  Shitty day night imagery is of little value to me.

Good and bad news.  The bad is, there still issues, but it's being worked on.  But some is updating.
   
The response.

Regarding the JPSS imagery, we have multiple issues that have been causing the sporadic data lately. There seems to be a new bottleneck somewhere upstream from CIRA that we haven't yet been able to getto the bottom of, which is leading to us not getting all the imagery we normally do. Then, this past weekend, there was a power outage in one of our server rooms that took everything down. While the power outage issues have been resolved, one of my colleagues is hard at work trying to get the upstream data feed working as well as it had been before.
