Now I understood.
Your working examples were really nice for me to understand the idea.
Thank you for this clarification.

I think the use of this convention is the best idea to save MultiIndex in netCDF.
Maybe we can start implementing this? ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,187069161

I think the problem is how to serialize `MultiIndex` objects rather than the array itself.
In your `encoded`, how can we tell the MultiIndex is `[('a', 1), ('b', 1), ('a', 2), ('b', 2)]` or `[('a', 1), ('a', 2), ('b', 1), ('b', 2)]`?
Maybe we need to store similar objects to `landpoint` for level variables, such as `latpoint` and `lonpoint`.

I think just using `reset_index` is simpler and easier to restore.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,187069161
