ESA Sea Surface Salinity Climate Change Initiative (Sea_Surface_Salinity_cci): Monthly sea surface salinity product, v2.31, for 2010 to 2019

The ESA Sea Surface Salinity CCI consortium has produced global, level 4, multi-sensor Sea Surface Salinity maps covering the 2010-2019 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 (see more in the user guide and product documentation available below and on the Sea Surface Salinity CCI web page).

An overview paper about CCI SSS is now published:

An updated version of CCI SSS (version 3.21) is now available on: https://catalogue.ceda.ac.uk/uuid/5920a2c77e3c45339477acd31ce62c3c ; 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.

欧洲空间局海洋表面盐度联合研究中心（ESA Sea Surface Salinity CCI consortium）编制了覆盖2010-2019年期间的全球性、第四级、多传感器海洋表面盐度地图。该数据集提供了25公里空间分辨率和1个月时间分辨率的海洋表面盐度（SSS）数据。数据在25公里EASE（等面积可伸缩地球）网格上进行空间采样，时间采样间隔为15天。此外，还提供每周产品。除了盐度信息外，误差信息也得到了提供（详情请参阅用户指南和产品文档，这些文档可在以下链接及海洋表面盐度CCI网页上找到）。关于CCI SSS的概述论文现已发表：Boutin, J., N.
