Figure subpanels

---------------------------------------------------

Technically there are two panels, they are named in the datasets as top and bottom, but the data is stored in the parent directory. Data provided for bottom panel.

---------------------------------------------------

List of data provided

---------------------------------------------------

The dataset contains salinity data:

- climatological mean from CMIP6 models (1950-2014)

- simulated trend from CMIP6 models (1950-2014)

---------------------------------------------------

Data provided in relation to figure

---------------------------------------------------

- ocean_salinity_cmip6.nc: climatological salinity (1950-2014) from CMIP6 models (black contours) in a bottom panel

- ocean_salinity_trends_cmip6.nc: salinity trends (1950-2014) from CMIP6 models (colored shades) in a bottom panel

CMIP6 is the sixth phase of the Coupled Model Intercomparison Project.

Notes on reproducing the figure from the provided data

---------------------------------------------------

The observational data from here (top panel) is taken from the file:

DurackandWijffels_GlobalOceanChanges_19500101-20191231__210122-205355_beta.nc. The field of interest are salinity_mean (shown as black contours) and salinity_change (shown in colourscale). The file was archived as input data for Figure 2.27. The link to this dataset is provided in the Related Documents section of this catalogue record.
