title: ~550-year climate periodicity in the Yunnan-Guizhou plateau during the late mid-Holocene: Insights and implications

description: This is the Supporting Information for Li et al. "550-Year Climate
 Periodicity in the Yunnan-Guizhou Plateau during the late Mid-Holocene:
 Insights and Implications" published in Geophysical Research Letters.
 The data comes from a stalagmite in southwestern China (27° 4' N,
 105° 5' E). The dataset includes the speleothem 230Th dating data
 (Table S1 in Supporting Information S1), the speleothem 230Th dating, 13C,
 lamina thickness, 18O, Sr/Ca and Mg/Ca data (Table S2), the updated 14C
 database from archaeological sites in southwestern China (Table S3), the
 calculated minimal occupation events as the unit of analysis by combining
 more than one 14C date (Table S4) and the summed 14C probability (SCP)
 records (Table S5). The Supporting Information S1 includes a pdf file
 (available through Zenodo) provided also contains details on the methods
 of all the lab work, the results of the trace elements, the demonstration
 of annual lamina and application of least-squares fit, the practices of
 calculating summed 14C probability (SCP) distributions in southwestern
 China and a discussion on how ENSO and local precipitation can influence
 the proxies. Additionally, there are supporting figures (Figure S1-S8) for
 the main text in Supporting Information S1. The speleothem 230Th dating,
 13C, lamina thickness, 18O, Sr/Ca and Mg/Ca data in this study are also
 available in the public paleoclimate database of the National Oceanic and
 Atmospheric Administration (NOAA)
 (https://www.ncei.noaa.gov/access/paleo-search/study/38059).
