SST BIAS

Figure number: Figure 3.24 From the IPCC Working Group I Contribution to the Sixth Assessment Report: Chapter 3

Description:

The figure has three panels.

Caption: Biases in zonal mean and equatorial sea surface temperature (SST) in CMIP5 and CMIP6 models. CMIP6 (red), CMIP5 (blue) and HighResMIP (green) multi-model mean (a) zonally-averaged SST bias; (b) equatorial SST bias; and (c) equatorial SST compared to observed mean SST (black line) for 1979-1999. The inter-model 5th and 95th percentiles are depicted by the respective shaded range. Model climatologies are derived from the 1979-1999 mean of the historical simulations, using one simulation per model. The Hadley Centre Sea Ice and Sea Surface Temperature version 1 (HadISST) (Rayner et al., 2003) observational climatology for 1979-1999 is used as the reference for the error calculation in (a) and (b); and for observations in (c).

Additional datasets:

Except CMIP5, CMIP6 and HighResMIP, WOA18 dataset is needed (https://www.ncei.noaa.gov/access/world-ocean-atlas-2018/bin/woa18.pl?parameter=t). File: woa18_decav81B0_t00_01.nc. It was cmorized with cmorizers/obs/cmorize_obs_woa.py from the above mentioned repository.
