update /g/data/ik11/grids/ocean_grid_*.nc

[aekiss]

/g/data/ik11/grids/ocean_grid_*.nc need updating.

/g/data/ik11/grids/ocean_grid_10.nc and /g/data/ik11/grids/ocean_grid_025.nc use the old topography and land mask, so ht, hu, kmt and kmu should be updated to match what's in /g/data/ik11/inputs/access-om2/input_20201102, which includes all the improvements discussed in #158.

/g/data/ik11/grids/ocean_grid_01.nc currently contains a much smaller set of variables, has variable names that differ from what's used in the coarser ones, and is missing dimension data. It would be much more useful if this was made consistent with the others. I'm not sure whether the variables depth_t and num_levels already match topog.nc and kmt.nc in /g/data/ik11/inputs/access-om2/input_20201102, so that would also be worth checking.

It may also be worthwhile keeping the current versions of /g/data/ik11/grids/ocean_grid_10.nc and /g/data/ik11/grids/ocean_grid_025.nc for those using the old topography.

I just saw this issue now.
@aekiss where are the grid files with new topography and land mask located? I've been using the old ones for interpolation of BGC initial conditions.

[aekiss]

The config.yaml files in the current configurations use MOM inputs from
/g/data/ik11/inputs/access-om2/input_20201102/mom*

oh, i was using /g/data/ik11/grids/ocean_grid_10.nc for getting geolon_t and geolat_t, which are not affected by the new topography or land mask. so it's all good actually :)

[aekiss]

I've updated the first post to specify that ht, hu, kmt and kmu should be updated.
Purely grid-related variables like geolon_t and geolat_t are OK.

Yes let's do this update!

[navidcy]

And let's make sure that the grids across all resolutions contain the same variables! Currently they don't and this creates an impasse in comparing results across models with different resolutions.

We are addressing these problems here: COSIMA/cosima-recipes#212

[aekiss]

I now think ht, hu, kmt and kmu should be deleted rather than updated - see COSIMA/cosima-recipes#212 (comment)
