Inquiry about seaice thickness output with timeseries.csh

[wangxiong]

Hi，everyone.
I am writing this thread to inquiry about whether icepack provides any sample output. When choosing CFS forcing data and running icepack alone. I found the timeseries plot of sea ice thickness output using timeseries.csh has a unexpected transition. To be specific, there is a sudden decrease and increse at the end of October. Is this situation normal? If there is any sample output, I can confirm this. If sample output is not available, has anyone noticed this issue?
Thanks.

We've noticed this as well. With Icepack, there is a weird effect where the sea ice grows very quickly in concentration in the Fall. This creates a lot of thin ice over the whole grid cell and hence causes the gridcell mean thickness to drop.

We do provide sample output for both Icepack and CICE as well so you can compare against your results. Please see the Icepack Version Index:

The furthest right column has a link to sample output (click "output"). You can see the transition you refer to in that sample output.
