Global Ocean Heat and Salt Content / Global Total Steric Sea Level Anomaly Fields

Global total steric sea level anomaly (TSSLA) fields

To download the total steric sea level anomaly files, you may download an individual file or a tar file of all years for a particular file type.
The WOA documentation includes information on downloading and reading the data.
