Hybrid Mean Sea Surface combining SIO/CNES_CLS15/DTU15

Type of dataset: auxiliary product

Digital Object Identifier (DOI): 

Condition of access: 2021 Hybrid MSS is distributed by AVISO under standard AVISO+ license agreement.

Contents: mean sea profile above T/P reference ellipsoid. This surface is available on a regular grid (1/60°x1/60°, 1 minute). Another grid provides the estimation of error fields which represent the MSS accuracy estimated through the inverse technique.

Use: geodesy, geophysics, oceanography (operational oceanography, modeling, ocean variability studies)

Description : The  2021 Hybrid MSS results from the combination of 3 different reference MSSs over the ocean:

  • The SIO MSS  (Sandwell et al, 2017) is used in the open ocean.
  • The CNES_CLS15 (Pujol et al, 2016) MSS used on coastal areas (<30km from the coast) and for the Antarctic region.
  • The DTU15 MSS (Andersen et al, 2016) used in Arctic regions (latitude> 80 N).

Geographic coverage: global.
