Global arboreal pollen database for Termination V (404-433 kyr BP)

This dataset is a global compilation of arboreal pollen records covering Termination V (~404-433 kyr BP).
1) Arboreal pollen proxy (Arboreal pollen (AP) or fern spores) percentages were computed for 19 pollen records covering large portions of Termination V (404-433 kyr BP) at a global scale (Sheet 1-19)
2) The compiled arboreal pollen proxy percentages were resampled with a 2-kyr timestep from 405 to 433 kyr BP (Sheet 20)
3) The resampled arboreal pollen proxy percentages were classified in four forest groups defined according to their main bioclimatic specificity (Eurosiberian-Boreoamerican (ES-BA), Subtropical-North, Tropical, Subtropical-South) (Sheet 21). The Eurosiberian-Boreoamerican group (ES-BA), as defined by Braun-Blanquet (1930), covers boreal and temperate forests. Therefore, both Tibetan Plateau pollen records (Heqing and ZB13-C2) are counted in the ES-BA group, the high altitude compensating for their relatively low latitudes. Although Tenaghi Philippon and Lake Ohrid records are on the geographical boundary with the Mediterranean region, they are also classified in the ES-BA group for they rather reflect a temperate forest cover. The Northern Hemisphere Subtropical group (Subtropical-N) encompasses warm temperate forests of the Northern Hemisphere and therefore extends beyond the geographical boundaries of the Mediterranean region (Mediterranean sensu lato). The Tropical group (T) refers to tropical and afromontane forests. Finally, the Southern Hemisphere Subtropical group (Subtropical-S) only includes the MD96-2048 record which is at the limit between tropical and subtropical forests (Table 2).
