Description:
This data set presents East Asian summer monsoon (EASM) and winter monsoon (EAWM) proxy record stacks for the last 10,000 years. Shown is the median value (X50) as well as its 1-sigma (X16; X84) and 2-sigma (X2.5;X97.5) uncertainty envelope. For the development of the stacks, we combined marine and terrestrial (non-speleothem) proxy records from the East Asian realm. Please see the supplementary information of Kaboth et al. (2021) for further details on the individual proxy records used. The individual EASM and EAWM records were linear resampled (0.1 kyr step size) and detrended before applying a low pass Taner filter with a cut-off frequency of 2 and a roll-off-rate of 10^10^. These steps were implemented to adjust for the differences in sample resolution and account for respective age uncertainties between the different proxy records, as well as remove the long-term insolation trend inherent to the selected records. The stacking was realized with an iteration loop with N=1000 iterations. For this we used the astrochron package implemented in the software R. Please see the method section in Kaboth-Bahr et al. (2021) for more details on the applied stacking algorithm.
