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

[simul]
duration=150
time_init=2006-11-15
timestep=900

[dynamics]
compression_factor=13800
C_lab=2675000
nu0=0.301
tan_phi=0.624
substeps=90
time_relaxation_damage=15
use_temperature_dependent_healing=true

output_per_day=4
variables=M_VT
variables=Concentration

[setup]
atmosphere-type=era5
ice-type=topaz_osisaf_icesat
ocean-type=topaz

[thermo]

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