Got it

Look, it's melting...

Notes for Year: 2013

Peter Wadhams, Professor of Ocean Physics and Head of the Polar Ocean Physics Group in the Department of Applied Mathematics and Theoretical Physic at the University of Cambridge, looks at sea ice models, how to improve them, and how to improve the quality of the IPCC’s assessment reports.

The most important Arctic monitoring results in 2013:

  • The Greenland Ice Sheet contributed net 1.2 mm freshwater to global sea level.
  • The surface mass balance was lower than normal with a gain of 166 Gt vs. an average since 1990 of 368 Gt.
  • The sea ice extent was 21 % lower than normal (5.9 million km2 vs. the 1981-2009 average of 7.5 million km2).
  • Record warmth in late July promoted strong ice sheet surface melting.
  • The wind helped to maintain both ice sheet and sea ice.
  • The glacier front positions had no strong deviations.

I'm using these relative silent weeks of the winter season to update a few parts of, especially the map interface will see major changes. So, this a first step to see what works and what not.

In case your curious check it out, I'll covering everything in detail once it works. The 'Satellite' entry from the top menu is now called 'Explorer' and links to the map interface. Available are now daily data from four satellites (AMSR2 w/ concentration, SMOS w/ thickness, Terra, Aqua) and the northern hemisphere true color images cover a larger region, even parts of Europe are included.

A completely new feature are forecasts from the Global Forecast System (GFS) with 4 steps per day - try using your mouse wheel with the fly-out calendar.
