Indices

⚠️ The multi model median depends on the models that are in the ensemble. A ensemble of opportunity is used here: all available models are included. Only one simulation per model is included.

Method

The regional statistics are calculated as follows:

1. calculate the index on the original model grid
2. calculate the area-weighted mean over the AR6 regions
3. calculate anomalies w.r.t. 1850-1900
4. calculate the mean over the years where a warming level is reached (see cmip_warming_levels)
5. calculate the multi model median

Code

The code is available under https://github.com/IPCC-WG1/Chapter-11/tree/main/code/Table_11.SM_cmip_indices_regional.ipynb.
