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