Contents & fields

The dataset contains global ocean reanalysis variables generated by ECMWF's ORA-S3 system, concatenated by CSIRO into single NetCDF files. Data are provided on a 256×195 lat-lon grid (29 levels) in four forms: monthly, anomaly, climatology, and seasonal. No field-level description is publicly available on the source page.

Research uses

Suitable for ocean circulation studies, climate variability and change analysis, initialization of coupled models, and seasonal to decadal predictions.

Why this is hard to get on your own

Ocean reanalysis data often have many variables, complex formats, and unclear licenses, making direct use for research or redistribution difficult.
