Climate Risk STAC: A living metadata catalog of geospatial data for climate risk assessments

Climate risks are increasing globally due to climate change, driven by intensifying climate hazards and changes in socioeconomic conditions that drive exposure and vulnerability. Climate Risk Assessments (CRAs) constitute a tool to understand such risks based on the analysis of geospatial datasets. However, CRA data are often scattered across different platforms, thereby inhibiting their Findability, Accessibility, Interoperability, and Reusability (FAIR). To make CRA data FAIR, we develop Climate Risk STAC, a living metadata catalog of open-access geospatial datasets that is hosted in a collaborative environment for continuous development. Climate Risk STAC (version 1.0) currently includes 214 metadata entries from nine different hazards, five types of exposed elements, and seven vulnerability categories. All data entries can be explored in a user-friendly browser which eases data selection. We encourage contributions of new datasets to maintain a growing, community-led catalog that reflects state-of-the-art CRA concepts and data.
