SMDT-MED-2014 - Combined mean dynamic topography

Mediterranean Sea

Types of dataset: auxiliary products

Contents: mean sea surface above geoid, corrected from geophysical effects. It is referenced over a twenty-year period [1993-2012].

Use: ocean circulation, operational oceanography.

Description: combined product covering 20 years (1993-2012) based on multi-platform observing systems, extended datasets and refined processing.
The Cnes and CTOH distribute this product courtesy of SOCIB. This MDT has been produced by CLS, IMEDEA (CSIC-UIB) and OGS with funds from SOCIB. 
The file distributed by Aviso+ is referenced to a twenty-year period [1993; 2012]. Moreover, a mean bias has been applied (1.13cm) in order to take into account the adjustment between the global MDT and the Mediterranean. However, the basin scale biases are not taken into account.
The file contains the Mean Dynamic Topography (MDT) and the associated error (MDTerror) on a 1/16 degree grid. More information about the processing can be found in the following reference:
