I have looked at these examples and I still don't manage to make it work in the real world. I find append the most logical but I have attributes attached to a dataset that I don't seem to be able to drop before appending. This generates this error: ValueError: failed to prevent overwriting existing key _FillValue in attrs. This is probably an encoding field used by xarray to describe how a variable is serialized. To proceed, remove this key from the variable's attributes manually. However, I cannot find a way of getting rid of this attribute
