Creating a new issue from PR #1235

Impacting ocean/seaIce nominal resolution for "AWI-CM-1-1-LR", "AWI-ESM-1-1-LR", "AWI-ESM-1-REcoM" and "AWI-ESM-2-1-LR" (deregistered)

Hi

This is an update of the nominal resolution of the ocean component of the low resolution AWI model settings after reviewing Appendix 2 of https://goo.gl/v1drZl.

dmax of the native, unstructured mesh is defined as sqrt(cell_area), following Danilov 2022 (https://doi.org/10.1029/2022MS003177).

Please excuse the confusion!
