Stable isotope records from speleothems provide information on past climate changes, most particularly information that can be used to reconstruct past changes in precipitation and atmospheric circulation. These records are increasingly being used to provide <q>out-of-sample</q> evaluations of isotope-enabled climate models. SISAL (Speleothem Isotope Synthesis and Analysis) is an international working group of the Past Global Changes (PAGES) project. The working group aims to provide a comprehensive compilation of speleothem isotope records for climate reconstruction and model evaluation. The SISAL database contains data for individual speleothems, grouped by cave system. Stable isotopes of oxygen and carbon (18O, 13C) measurements are referenced by distance from the top or bottom of the speleothem. Additional tables provide information on dating, including information on the dates used to construct the original age model and sufficient information to assess the quality of each data set and to erect a standardized chronology across different speleothems. The metadata table provides location information, information on the full range of measurements carried out on each speleothem and information on the cave system that is relevant to the interpretation of the records, as well as citations for both publications and archived data. The compiled data are available at <a hrefCombining double low line"https://doi.org/10.17864/1947.147.

Additional financial support for SISAL activities has been provided by the European Geosciences Union (EGU TE Winter call, grant number W2017/413), Irish Centre for Research in Applied Geosciences (iCRAG), European Association of Geochemistry (Early Career Ambassadors program 2017), Geological Survey Ireland, Quaternary Research Association UK, Navarino Environmental Observatory, Stockholm University, Savillex, John Cantle, University of Reading and University College Dublin (Seed Funding award, grant number SF1428). The design and creation of the database has been supported by funding to Sandy P. Harrison from the ERC-funded project GC2.0 (Global Change 2.0: Unlocking the past for a clearer future, grant number 694481) and by funding to Laia Comas-Bru from the Geological Survey Ireland Short Call 2017 (Developing a toolkit for model evaluation using speleothem isotope data, grant number 2017-SC-056). Sandy P. Harrison also acknowledges funding from the JPI-Belmont project “PAlaeo-Constraints on Monsoon Evolution and Dynamics (PACMEDY)” through the UK Natural Environmental Research Council (NERC). We thank SISAL members who contributed their published data to the database and provided additional information when necessary.
