     "As of March 2023, ECCOv4 release 4 state estimate fields are distributed through PO.DAAC/ NASA Earthdata Cloud, and are stored as NetCDF files, with each file containing one [granule](https://ecco-v4-python-tutorial.readthedocs.io/Downloading_ECCO_Datasets_from_PODAAC_Python.html#ECCO-output-structure-on-PO.DAAC-%28NASA-Earthdata-Cloud%29).
