Introduction
The LegacyClimate 1.0 database is a dataset of mean July temperature (TJuly), mean annual temperature (Tann), and annual precipitation (Pann) reconstructions from 2594 fossil pollen records from the Northern Hemisphere. The records span the entire Holocene, with some reaching back to the Last Glacial Period (last 30 kyr and beyond). This community-vetted, open-source, version-controlled database is intended to serve as a hub for paleoclimate data synthesis and data–model comparisons.
Conversion to LiPD
This compilation has been converted from its original format into LiPD programmatically using code at https://github.com/nickmckay/LegacyClimate2lipd. Additionally, many of the datasets have been annotated with additional metadata, including describing the climate interpretation, and adjusted to match the LiPDverse vocabulary.

Publication
A data descriptor for the compilation was published in Earth System Science Data and is available here.
