@dcherian. 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
}

@dcherian 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
}
