With SubX the data will be remote.
Is the data hosted on an OpenDAP server?

Is the data hosted on an OpenDAP server?
I just took a look at the script above, and it appears to be reading the data remotely via xarray+openDAP.
Would it be useful and feasible to build a catalog for SubX ?
Is it feasible? Yes, this is doable today. There was an issue about this on intake-esm issue tracker: intake/intake-esm#175
from intake-esm-datastore.
Here's an example of catalog pointing to an OpenDAP server: http://haden.ldeo.columbia.edu/catalogs/hyrax_cmip6.json
from intake-esm-datastore.
Great. I will give this a try tomorrow. The json file looks like cmip6 data and hopefully the structure can get copied a bit.
Any ideas on running a builder there?

I dont get to the individual nc files: http://iridl.ldeo.columbia.edu/SOURCES/.Models/.SubX/.NCEP/.CFSv2/.forecast/.pr/dods
where I cannot look further. Anyone an idea?
import xarray as xr
url = 'http://iridl.ldeo.columbia.edu/SOURCES/.Models/.SubX/.RSMAS/.CCSM4/.hindcast/.zg/dods'
remote_data = xr.open_dataarray(url, chunks={'S': 1, 'L': 1})

the subX output is already concated together in a useful form with dims (S, L, M, X, Y). sure having model included there would be nice, but the datasets are very heavy. I guess a more simple intake-xarray
yaml file also does it fine to start with.
