ISIMIP Repository
The ISIMIP Repository supports searches for climate forcing and related input data across simulation rounds.
About ISIMIP Repository
The ISIMIP Repository is a web-based search interface for climate forcing and related input data used in ISIMIP simulation rounds. It organizes data into input categories (climate forcing, socioeconomic forcing, and static geographic information) and output categories by sector, including agriculture, water, permafrost, and fire. Users first select a simulation round, which covers ISIMIP2a through ISIMIP4b depending on the category.
The repository also lists derived input and output datasets, several with DOI links for citation. Availability depends on both the simulation round and the sector: the homepage shows that not every sector is listed for every round. The homepage does not state licensing or download terms, and pricing is unknown.
Key features
- Browse climate forcing data for ISIMIP2a through ISIMIP4b simulation rounds
- Socioeconomic forcing datasets for ISIMIP2a through ISIMIP3b rounds
- Static geographic information for ISIMIP2a through ISIMIP3b rounds
- Sector output data covering agriculture, water, permafrost, fire, and biodiversity
- Derived input and output datasets with DOI links for citation
Best for: Climate impact researchers who need ISIMIP input or output datasets for a specific simulation round or sector.
Good for
- Brings forcing, socioeconomic, geographic, and sector output data from several rounds into one interface
- Derived datasets are listed with DOI links and author credits
Watch out for
- Sector availability varies by simulation round, so not every sector is available in every round

ISIMIP Repository FAQ
Which simulation rounds does the repository cover?
Climate forcing data covers ISIMIP2a, ISIMIP2b, ISIMIP3a, ISIMIP3b, ISIMIP4a, and ISIMIP4b. Socioeconomic forcing and static geographic information cover ISIMIP2a through ISIMIP3b.
Which sectors have output data?
Listed sectors include agriculture, terrestrial biodiversity, biomes, fire, regional forests, temperature-related mortality, lakes (global and local), fisheries and marine ecosystems (global and regional), permafrost, and water (global and regional). Each sector lists the rounds that include it.
How can I identify derived datasets?
Derived entries on the homepage show a title, authors, year, a DOI link, and a note on which ISIMIP round the input or output data comes from.
