| product_version | 3-21 |
| comment | The following caveats must be considered: 1) Products have not been fully optimised for very high latitudes, 2) There is a systematic global underestimation of ~0.1 pss early 2010 that gradually disappears over the year, 3) Products are in general of better quality after 2015 due to the inclusion of SMAP data and reduced contaminations (RFI, sun) on SMOS data. We (Mngt_CCI-Salinity@argans.co.uk) are very keen to get users feedbacks about these products |

| 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. |
