Outputs of the next generation sea ice model (neXtSIM) for winter 2006 - 2007 saved for comparison with RGPS.

NeXtSIM was run from 1 December 2006 to 15 April 2007 with the following parameters:

[mesh]filename=small_arctic_10km.msh

The outputs (binary snapshots at every 3 hours) were then merged with RGPS data from the same period using this notebook:
