Chapter 2 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 2.38 (v20221115)
Abstract
Data for Figure 2.38 from Chapter 2 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6).
Figure 2.38 shows indices of multi-decadal climate variability from 1854-2019 based upon several sea surface temperature data products.

List of data provided
---------------------------------------------------
- AMV.nc contains Atlantic Multidecadal Variability (AMV) index from COBE, ERSST, HADI and KAPL.
- PDV.nc contains PDV index from COBE, ERSST, HADI and KAPL.
Data acronyms:
COBE [Objective Analyses of Sea-Surface Temperature and Marine Meteorological Variables for the 20th Century using ICOADS and the Kobe Collection].
ERSST [NOAA Extended Reconstructed Sea Surface Temperature].
HADI [Hadley Centre Sea Ice and Sea Surface Temperature data set].
KAPL [Kaplan Extended SST].
