Abstract:
The modern pollen data from arid central Asia (Bordon et al., 2009, doi:10.1016/j.quaint.2008.05.014) and our newly completed modern pollen data from southwest Siberia (unpublished) was homogenized and combined into the modern pollen dataset (Cao et al., 2014, doi:10.1016/j.revpalbo.2014.08.007). In this study, the 808 modern pollen sites 1000-km around Bayan Nuur were selected to establish pollen-climate calibration-sets. PANN was selected as the target climatic variable for past climate 206 reconstruction. The model performance of cross-validation for the pollen-PANN calibration-set has high R2 (0.79) and low RMSEP (71 mm). A quantitative PANN reconstruction was performed using the WAPLS function in rioja package version 0.7-3 (Juggins, 2012) for R with square-root transformed pollen data.
