Dataset supporting the University of Southampton doctoral thesis "Dynamics of the subpolar southern ocean response to climate change"

Dataset title: Gridded Altimetric Dynamic Ocean Topography for the Southern Ocean

Southern Ocean product providing dynamic ocean topography to the south of 50S including over the ice covered regions. The gridded product combines data collected during two satellite missions monitored by the European Space Agency: Envisat and CryoSat-2. Along-track Sea Surface Height data referenced to the WGS84 ellipsoid are provided by the Centre of Polar Observation and Modelling and the University College London.
Along-track data are processed to obtain a merged gridded product of monthly averages of Dynamic Ocean Topography (DOT) that span the period from July 2002 to October 2018.

The DOT estimates are referenced to three geoid products:
- GOCO05c
- EGM2008
- EIGEN64v4
A separate file is avaialble for every geoid product used as a reference.

The data in all files are binned on a 0.5 degree latitude x 1 degree longitude grid and have a Gaussian filter with a 300 km radius applied.
Further details can be found in the linked Git repository.
