List of data provided

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

This dataset contains observed global patterns for:

- temperature from the Berkeley Earth dataset over land

- temperature from ERSSTv5 over ocean

- precipitation from GPCC over land (shading, mm day–1)

- precipitation from GPCP worldwide (contours, period: 1979-2014)

and distributions of regression coefficients in IPCC regions for:

- temperature

- precipitation

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

Data provided in relation to figure

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

maps:

- reg_tas_NINO34_BEST_ERSSTv5_1901_2018_DJF.nc (var = 'rc', upper map over land)

- reg_sst_NINO34_ERSSTv5_ERSSTv5_1901_2018_DJF.nc (var = 'rc', upper map over ocean)

- reg_precip_NINO34_GPCP_ERSST5_1979_2018_DJF.nc (var = 'rc', lower map, contours)

- reg_pr_NINO34_GPCC_ERSSTv5_1901_2016_DJF.nc (var = 'rc', lower map, shading)

histograms:

- tas_enso_regression_pdf_v4_no_cosweight_DJF.nc

. upper grey histograms: var = 'region_pdfx_hist' and 'region_pdfy_hist'

. MME (black line): var = 'region_ave_hist'

. Observations (blue lines): var = 'region_obs'

- tas_amip_hist_enso_regression_pdf_v4_no_cosweight_DJF.nc (orange dashed line): var = 'region_ave_amip_hist'

=> Fields correspond to regions numbers with labels in the plot, namely for temperature: 'EAU/RFE/RAR/NWN/NCA/ENA/NSA/MED/NWS/ESAF' (see variable region_info with attributes making the association between the region index and the acronym/name).

- pr_enso_regression_pdf_v4_no_cosweight_DJF.nc

. lower grey histograms: var = 'region_pdfx_hist' and 'region_pdfy_hist'

. MME (black line): var = 'region_ave_hist'

. Observations (blue lines): var = 'region_obs'

- pr_amip_hist_enso_regression_pdf_v4_no_cosweight_DJF.nc (orange dahsed line): var = 'region_ave_amip_hist'

=> Fields correspond to regions numbers with labels in the plot, namely for precipitation: 'EAS/SEA/EAU/WNA/NCA/SES/NSA/ESAF/SEAF/MED' (see variable info_region with attributes making the association between the region index and the acronym/name).

ENSO is the El Niño Southern Oscillation.

GPCC is the Global Precipitation Climatology Centre.

GPCP is the Global Precipitation Climatology Project.
