The COMPASS project recently released a report on “Exposure datasets at multiple scales”.
This report is a data deliverable, hence this report only documents the dataset without providing a detailed analysis. The data is a gridded dataset of global exposure (population, gross domestic product and net fixed asset value), as described also at the following figure, at a spatial resolution of 30 arc seconds (≈0.93 km at the equator) and lower. It spans years 1850 to 2100, has an annual temporal resolution and includes five future trajectories consistent with the Shared Socio-economic Pathways (SSPs). Due to the large file sizes, only a selection of spatial resolutions and timesteps is provided in the repository, but the code and input data provided alongside the dataset enable users to generate different resolutions and timesteps as required by their research needs.
The exposure dataset and input data for its generation (currently v1.0 at the time of writing) are available on the COMPASS research repository Zenodo at the following DOI: 10.5281/zenodo.14892500
The code is hosted at the following repository: https://github.com/HORIZON-COMPASS/Exposure-and-vulnerability-modelling under the COMPASS Github repository. The version of the code using in the deliverable is in the ‘D3_1_final’ branch (https://github.com/HORIZON-COMPASS/Exposure-and-vulnerability-modelling/tree/D3_1_final) and under the release D3.1 (https://github.com/HORIZON-COMPASS/Exposure-and-vulnerability-modelling/releases/tag/D3.1).
Note: the use of term ‘country’ as well as the specific representation of national and subnational boundaries used in the data and documentation does not represent a particular point in time, but is done for practical and statistical purposes.
