Supplementary data from: Quantitative contribution of major organism groups to lake organic carbon burial since the last glacial inferred from sedimentary ancient DNA

This dataset presents temperature and precipitation reconstruction from pollen records of the six lakes in alsike and sibiariya. The pollen proxy data were retrieved from LegacyClimate 1.0 (https://doi.org/10.1594/PANGAEA.930512). Mean July temperature, annual mean temperature and annual precipitation were reconstructed using the full modern temperature and precipitation range, as well as using a "tailored" version, where we restricted a climate variable range to reconstruct the respective other climate variable in order to minimize the impact of co-correlation. Statistics on the used calibration sets (i.e. all samples within 1000 km distance to the fossil pollen records) are also provided, as well as results from the significance test of the reconstructions sensu Telford & Birks (2011).
