Sea Surface Salinity Database in the Atlantic Ocean 50°N-30°S for the 1970-2013 period

Par Webmaster Legos Dernière modification 30/09/2014 06:24

NEW VERSION UPDATED TO 2013

Written by Elodie Kestenare in February 2005 (last updated: March 2015)


The observed SSS fields developed by Reverdin et al (2007) have been recently extended to 2013. As in Reverdin et al (2007), the monthly SSS are gridded using an objective mapping at the spatial resolution 1° x 1° .

The new files (1970-2013) are freely downloadable here

  • Monthly SSS after objective analysis: sss_postobj_7013_ATL50N30Sreg1x1.nc
  • Monthly SSS before objective analysis: sss_raw_7013_ATL50N30Sreg1x1.nc

 

The previous datasets (1970-2002) are not available anymore.

  • Monthly Anomalies after objective analysis for the 1970-2002 period
    sssAnom_postobj_7002_ATL50N30Sreg1x1.nc (28Mo gzipped, 60Mo gunzipped).
  • Monthly Anomalies before objective analysis for the 1970-2002 period
    sssAnom_raw_7002_ATL50N30Sreg1x1.nc (3.7Mo gzipped, 90Mo gunzipped).
  • Mean seasonal cycle (Climatology) after objective analysis based on the 1977-2002 period
     sssClim_postobj_7702_ATL50N30Sreg1x1.nc (1Mo gzipped, 2Mo gunzipped).
  • Mean seasonal cycle (Climatology) before objective analysis based on the 1977-2002 period
    sssClim_raw_7702_ATL50N30Sreg1x1.nc (0.6Mo gzipped, 3Mo gunzipped).
