Analysis of a new annually resolved, multi-method, palaeoproxy-derived reconstruction ensemble for the period 1200–2000 suggests that recent variability in the Pacific Walker circulation is unusual but not unprecedented over the past 800 years.
We only used CESM1 LME members with all anthropogenic and natural external forcing factors applied, that is, fully forced ensemble members . The PMIP3 data include an extra single-model ensemble .We chose the 1200–2000 interval for reconstruction, as this struck the best balance between proxy data availability and sampling of long-term forced and internal variability.We used two calibration windows.
We recalculated the full ΔSLP reconstruction ensemble using a shorter calibration window , providing a minimum estimate of reconstruction skill through independent validation tests performed over 1900–1950 .We reconstructed annual ΔSLP, allowing characterization of both long-term interannual PWC variability and lower-frequency variability. Most reconstruction methods require data on a common time step, so sub-annually resolved records were annually binned to calendar years .
