An interruption in normal Polar Portal service this week has brought unexpected benefits for DMI’s daily surface mass balance data from Greenland… upgrading to the cutting edge HARMONIE-AROME modelling system.

This summer’s ablation season began on June 11 – the first of three days in a row with more than one gigatonne mass loss across Greenland. This date places this year on a shared 12th place over the 1981-2017 period, just one day from June 12, which...

One week ago, we launched a new and improved surface mass balance data product on the Polar Portal. The improvements in the underlying model include changes in the details of how water from melted snow percolates into the snow layers below, where it...

A new and improved surface mass balance data product has just been launched on the Polar Portal. This upgrade to the existing model not only improves the way the snow pack is handled in the model used to calculate surface mass balance, it also...

This winter has seen a series of unusual weather hit the Arctic in general, it has been much warmer than average in the high Arctic since October though there have also been some periods of extreme cold, especially in western Greenland but also new...
