Framework for Assessing Changes To Sea-level (FACTS) modules, scripts, and data for the IPCC AR6 sea level projections

This package contains the Frameworks for Assessing Changes To Sea-level (FACTS) modules, data, and scripts used to produce the sea level projections in the Intergovernmental Panel on Climate Change Sixth Assessment Report (AR6).

FACTS modules are located in the modules.zip file. Scripts for executing these modules are located in the scripts.zip file.

The CMIP6 zos (sea surface height) data used by the tlm ocean dynamics module are located in module-data-zos.zip. All other input data used by the modules are located in module-data.zip. Symbolic links from the modules subdirectories should point to data files in the corresponde modules-data subdirectories.

Required Acknowledgements and Citation

In order to document the impact of these sea-level rise projections, users of the projections are obligated to cite chapter 9 of Working Group 1 contribution to the the IPCC Sixth Assessment Report, the Framework for Assessment of Changes To Sea-level (FACTS) model description paper, and the version of the data set used:
