@lewisjared The decimation on the variable msftmz failed because its dimensions are time, basin, lev, lat. The portion I am using as test data (2000-2014) is not too big. I am not sure how to decimate it. We could, instead of raising a ValueError if there isn't both lat and lon, just not decimate. Any preference?

I'm happy with the approach of not decimating this particular dataset

@lewisjared It is not clear to me how to declare a dataset that I intend to not decimate. I see the boolean provided to the command create_sample_data, but this seems to be a constant for all the datasets in DATASETS_TO_FETCH.

My naive approach would be to:

1. Remove that option from create_sample_data and set decimate=True in the current loop over DATASETS_TO_FETCH.
2. Create a new constant DATASETS_NOT_DECIMATED with just my msftmz variable in a CMIP6Request.
3. Write a second loop in create_sample_data over this new list and set decimate=False

Am I missing something? Another approach would be to add a flag to each request to decimate or not, default to True, and then explicitly flag my request as false.

That functionality hasn't been added. The intended use-case for the CLI argument was to produce a directory with the same datasets, but not decimated for local testing. Ignoring the decimation at a request level would require some rework.

Honestly for this particular grid, I would add update CMIP6Request.decimate_dataset to support the dimensions and just return the dataset unchanged. That is the lightest touch approach to this.
