resources of deep ocean heat flux (qdp) needed for icepack run

[chenshzh12]

Hi,
Could you please let me know where may I find more realistic or recent data of the deep ocean heat fluxes which are needed for the icepack run? I am now using the POP gx1v3 deep ocean heat flux data which might be out-of-date.
Thank you in advance

We are not formally supporting the mixed-layer ocean model in Icepack/CICE. For an icepack run, you can prescribe whatever values you want.

Hi,

Thank you for your response. I understand that the mixed layer depth and QDP can be prescribed for the icepack run. My further question is that in order to make the icepack simulation more "realistic", I want to find a more "realistic" QDP resource so I can give icepack a better-prescibred qdp (ocean forcing). For example, the mixed layer depth is common and can be easy to find in many ocean reanalysis datasets like ORAS5, etc. So I am wondering if there's any resource out there that I can find the QDP. So far I haven't got any luck in finding the QDP in any of the ocean reanalysis dataset.

Thank you.

Hi Shengzhe,
There is a master's thesis on the Consortium's zenodo community page
https://zenodo.org/record/4058189#.X6l23i9h1-U
which includes some discussion of the deep ocean heat flux for simulations of the SHEBA year. She found that there were unrealistic summer growth periods and attributed them to the deep ocean heat flux input data. She ameliorated the problem by using SST restoring. This kind of behavior is part of the reason that we only recommend that the CICE and Icepack models be used in coupled mode, with active ocean and atmosphere models. The forcing data that we provide is primarily for code testing and model evaluation, not for publishable production runs. I don't know of QDP data available from other data sets.
Best,

Thank you very much! Will read the thesis and try to understand it.
