调研方向

Start by reviewing the existing tutorial coverage for reindex, reindex_like, groupby, and groupby_bins, then examine the linked Stack Overflow example. Done would be practical guidance or examples for indexing and re-indexing with gappy or poorly gridded data, including whether these topics are already covered.

描述

enhancement

xarray has some pretty powerful, indexing, re-indexing, and binning capabilities. My knowledge of them all is pretty limited, but reindex, reindex_like, groupby and groupby_bins all seem like useful targets for operations that folks dealing with practical, happy gappy, poorly gridded data, could use some help with.

e.g. I couldn't figure this out on my own: https://stackoverflow.com/questions/73760046/replace-some-values-in-dataarray-based-on-list-of-indices/73790162#73790162

I appreciate that some of this is probably old-hat for pandas users, but some of us just skipped right to xarray ;-)

Thanks!

PS, apologies if this is covered in the tutorial and I haven't seen it.
