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.
