Jacobshavn is further south so the orbits are wider apart. Further the preferred
acquisition mode is higher resolution IW (Interferometric Width) rather than the EW (Extra Width) products I use for Nares. Better resolution->narrower swath->longer return times. Perhaps the DMI images can only use EW products?
From the following list we can deduce that at the moment data is missing for 2014-12-30 and perhaps 2015-01-03. The datahub servers seem to be very stressed at the moment, so that may cause the delay.

The EW, dual polarization images listed (Nov 29 and later) suggsts a new product today.

I will have a look at the preview images when the servers start responding again.
PS. for the single polarization mode (in the fourth field, SH means "Single HH polarization available") the quick look images are in B&W
