Abstract

This dataset contains the input data for Figure 2.27 from Chapter 2 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Seventh Assessment Report (AR7). Additional information, including how to cite this figure dataset, is provided in the README.txt alongside the data.

Figure 2.27 caption: Changes in ocean salinity.
Estimates of salinity trends using a total least absolute differences fitting method for (a) global near-surface salinity (SSS) changes and (b) global zonal mean subsurface salinity changes. Black contours show the associated climatological mean salinity (either near-surface (a) or subsurface (b)) for the analysis period (1950–2019). Both panels represent changes in Practical Salinity Scale 1978 [PSS-78], per decade. In both panels green denotes freshening regions and orange/brown denotes regions with enhanced salinities (‘×’ marks denote non-significant changes). Further details on data sources and processing are available in the chapter data table (Table 2.SM.1).

Links to the figure, report chapter and supplementary material are provided in the Details/Docs section of this catalogue record. Code to reproduce the figure which is hosted on GitHub is also linked, and described under the Process tab of this catalogue record.
