<Summary>Macroscopic charcoal records and radiocarbon age dating information of sediment cores from eight lakes in central and eastern Yakutia. Sediment cores were obtained during fieldwork in August 2021, jointly organized by the Alfred Wegener Institute and the North-Eastern Federal University of Yakutsk. Charcoal data includes the total amount of particles per sample as well as their respective distributions in size classes (150-300 µm, 300-500 µm, &gt; 500 µm), morphotype categories, and (for some of the records) average particle length-to-width ratios. More detailed information about the data and an approach to age-depth modelling can be found in the research paper (in preparation). Details of fieldwork in 2021 is available in the corresponding expedition report (Morgenstern et al., 2023). ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.974689"!</Summary>
