PAGES' Speleothem Isotopes Synthesis and Analysis (SISAL) working group will hold their second workshop, titled "Speleothem isotope records for climate model evaluation", in Stockholm, Sweden, from 20-22 September 2017.

Venue

Navarro Environmental Observatory
Department of Geological Sciences
University of Stockholm
Sweden

Logistics

This is an open workshop but limited to 25-30 participants. It will draw on the SISAL WG membership, modelers from the PMIP community and representatives of the Iso2k sub-group of the PAGES2k Network. Between 5-10 places will be reserved for other scientists to attend.

Description

The SISAL WG is a community-effort to compile the many hundreds of speleothem isotopic records worldwide, with careful screening, construction of standardised age models, and documentation of measurement and age-model uncertainties. SISAL will produce a public-access database and publications to document this, and make use of the database to analyse past changes in climate and atmospheric circulation.

A major motivation for creating the database is to provide a tool to evaluate state-of-the-art climate models that explicitly simulate water and carbon isotopes and/or atmospheric tracers. Several modeling groups running paleoclimate simulations during the current phase of the Coupled Model Intercomparison Project (CMIP6/PMIP4) are using isotope- and tracer- enabled models. We will discuss the use of speleothem data for model evaluation at the SISAL WG kick-off meeting in June.

We have made substantial progress on the SISAL database and data collection since last December and we confidently expect to produce a first version of the database (ca 150 records) by Northern Hemisphere autumn 2017, making it timely to hold a second workshop aligned with the PMIP meeting (September 2017) to design data-model comparisons that SISAL will carry out before the 2018 workshop.

Workshop goals

The goals of the workshop are:

- to design evaluations of existing isotope-enabled simulations using the first version of the SISAL database to be carried out as proof-of-concept exercises during 2017/2018;
- to discuss how the SISAL data should be made available to climate-modeller end-users;
- to determine priorities for data collection (time periods, regions) in 2018 to maximise the usefulness of SISAL data for CMIP6/PMIP4;
- to discuss climatic interpretation of isotope data, in order to co-design data analyses that will address this issue.
