Appendix for the article "Pollen-based reconstructions of European paleoclimates since the last glacial maximum: (mega)-biomization and multimethod approaches" by Fénisse G, Chevalier M, Peyron O, Bekaert D.V, Blard P-H

1. Site location, type of archives (a) and pollen description using taxonomic diversity parameters (b) and AP/NAP percentages (c) in 43 pollen LGM records.
2. Modern climate areas (Mean Annual Temperature vs. Mean Annual Precipitation) from the EMPD2 dataset.
3. Relationship between biome and megabiome
4. Pollen taxa observed
5. Percentage of arid megabiomes (STEP+DESE+TUND) at the LGM in 43 pollen sequences. Red contour points referred to the TEDE dominant megabiomes. SAVA scores are negligible.
6. Standard deviation of annual temperature (a), precipitation (b), MTWA (c) and MTCO (d) anomaly results (LGM – Modern climate) using averages of biomisation results from 3 different methods.​​
7. Monthly (MTWA and MTCO) temperature anomaly (LGM – Modern climate) results, using the megabiomisation process for the three different pollen-based climate reconstruction methods.
8. Cross validation procedures between observed and predicted modern climate variables of the pollen datasets (EMPD2 dataset).
9. Mean annual and monthly map anomalies reconstructed using three methods based on biomisation and megabiomisation, compared with Davis et al. (2024).
