Abstract

The ESA Sea Surface Salinity Climate Change Initiative (CCI) consortium has produced global, level 4, multi-sensor Sea Surface Salinity maps covering the 2010-2020 period.

This dataset provides Sea Surface Salinity (SSS) data at a spatial resolution of 25 km and a time resolution of 1 month. This has been spatially sampled on a 25 km EASE (Equal Area Scalable Earth) grid and 15 days of time sampling. A weekly product is also available. In addition to salinity, information on errors are provided. For more information, see the user guide and other product documentation available from the linked Sea Surface Salinity CCI web page.

Compared to the previous version of the data, version 3 SSS and associated uncertainties are more precise and cover a longer period (Jan 2010-sept 2020); version 3 SSS are provided closer to land than version 2 SSS, with a possible degraded quality. Users might remove these additional near land data by using the lsc_qc flag.

Title CCI Sea Surface Salinity retrieval
Abstract ESA CCI Sea Surface Salinity ECV Data has been produced at a spatial resolution of 50 km spatially resampled on 25 km EASE grid with a) a time resolution of 1 week and 1 day of time sampling and b) a time resolution of 1 month and 15 days of time sampling. For details of the algorithm see the documentation from the CCI Sea Surface Salinity project.
