Description

I think a good "infrastructure" target for the NASA OSS call would be to expand our benchmarking suite (https://pandas.pydata.org/speed/xarray/#/)

AFAIK running these in a useful manner on CI is still unsolved (please correct me if I'm wrong). But we can always run it on an NCAR machine using a cron job.

Thoughts?

Research direction

Start with the linked pandas/xarray benchmark page and inspect the repository's existing benchmarking and CI setup. Use the unchecked targets and referenced issues to define a focused first slice; done should include benchmarks for that slice plus an agreed CI or NCAR cron execution path.
