Fine resolution SSS and SST maps in the region south of Tasmania

Fine resolution SSS and SST based on low-resolution in-situ maps stirred by altimetry.

SSS advected field SST advected field


SST (left) and SSS (rigth) advected fields for the 1st January 2004 constructed from low-resolution tracer fields with -13 days of lateral stirring by altimetry.

Brief Description

Lateral advection from altimetry allows us to re-produce small scales tracer patterns at the ocean surface, starting from larger temporal and spatial scale tracer observations.


We advect the tracer particles using weekly or daily global 1/3 degree gridded fields of surface geostrophic velocities calculated from sea surface height (SSH) fields distributed by Aviso over the period 2002-2012.


Using these lagrangian 'advected' fields, we stir large-scale surface tracer fields (from the the CORIOLIS data center) enabling us to derive higher-resolution surface data.
