PACMEDY results

This section gathers the final results of the project. It will be updated gradually during the course of the project and only concerns public results. For PACMEDY partners the Work section which is password protected gathers more detailed information and ongoing work.

This section prodide information on the access to the different datasets produced by PACMEDY partners or to which PACMEDY partners have contributed


The BIOME 6000 data set provides pollen-based reconstructions of vegetation at 21,000, 6000 and 0 yr BP. The updated version of the BIOME 6000 database is available from:

Improved coverage for the Eastern Mediterranean, Middl east and the Black Sea-Caspian corrdior (EMBSeCBIO) us available from: Harrison, S.P. and Marinova, E., 2017. EMBSeCBIO modern pollen biomisation. University of Reading Dataset.

An improved coverage of modern surface samples for vegetation and climate reconstructions is available from: Harrison, S.P., 2019. Modern Pollen Data for Climate Reconstructions, version 1 (SMPDS). University of Reading Dataset.

Two data sets have been produced to facilitate the use of the BIOME6000 data for climate reconstruction: Wei, D., Harrison, S.P. and Prentice, I. C., 2019. The climatic space of European pollen taxa. University of Reading. Dataset.

Global Lake Status Database Update

The Global Lake Status Database (GLSDB( provides reconstructions of changes in regional hydroclimate, specifically precipitation minus evaporation (P-E) based on interpretation of lake sedimentary and geomorphological data. Updates have been produced for Africa and Eurasia (currently publications in review) and are available from Sandy P. Harrison (

Reading Paleofire Database

The Reading Paleofire Database (RPD) is a update of the Global Charcoal Database, which provides sedimentary charcoal records documenting changing fire regimes. Updates have been produced for the northern mid- to high-latitudes, the circum-Mediterranean region and the neotropics.

Contact person : The database is available from Sandy P. Harrison (

Reference : Publications documenting the RPD are currently in review.

SISAL (Speleothem Isotopes Synthesis and AnaLysis Working Group) :

SISAL (Speleothem Isotopes Synthesis and AnaLysis Working Group) database. The SISAL database contains oxygen and carbon isotope data from speleothems worldwide.

Contact person : Sandy P. Harrison (

The first version of the database is available from:

The second version of the database has been published: Comas-Bru, L., Atsawawaranunt, K, Harrison, S.P. and SISAL Working Group Members, 2020.

Mollusc data as a proxy for Sahel precipitation

Reconstruction of monsoon rainfall in western Sahel in the past 1600 year from the oxygen isotopic values of fossil mollusc shells from the Saloum estuary in Senegal

The dataset is publicly available in the PANGAEA repository:

Tropical ocean multi proxy synthesis

The SENSETROP tropical ocean multi proxy synthesis includes paleotemperature estimates derived from alkenones and foraminifera Mg/Ca proxies in oceanic sediment cores, and stable isotope values ; it has been updated to include Holocene records within the Pacmedy project.

This database named SENSETROP is hosted on, allows interactive queries and data are still under embargo until the final publication.

Contact person : Access to the webserver is open under request to Thibault de Garidel, CEREGE (

Update of the shell and coral database covering the tropical oceans

Contact person : The synthesis is currently available upon request to Matthieu Carré (

Tree rings and speleothems over India

Tree rings and speleothem data reconstructions have been achieved as part of PACMEDY and are available upon request.

* Speleothem data from the peninsular India :

The dataset cover the period 1720-3180 Years BP :

The following simulations can be directly accessed through internation or modeling group data facilities. Other results can be made available upon request.

Simulations of the midHolocene and the last millennium have been run following the international PMIP4-CMIP6 protocol. They are stored on the ESGF facilities following the CMIP data request. Details on these simulations and access to the database are available on PMIP website

These PMIP4/CMIP6 simulations have been run by LSCE, Reading, MPI-M, HZG, Stockholm, and AWI as part of PACMEDY

You can access here the key slides corresponding to ongoing PACMEDY activity.
