MORE INFORMATION
- It also includes associated statistical fields of observed oceanographic profile data interpolated to standard depth levels on 5°, 1°, and 0.25° grids.
- Some variables only have 37 or 57 depth levels at seasonal and monthly temporal resolution.
- Climatologies for different time periods are available.
