Input data set: Gross Domestic Product (GDP) — National (ISIMIP4)

Total gross domestic product at national level, in US dollars in 2017 price level and 2017 Purchasing Power Parity, with annual timesteps.
Countries and other territories are identified by ISO 3166-1 code. Data is harmonized to a single delineation of boundaries reflecting actual present-day availability of statistical data.

This dataset was created in Horizon Europe project COMPASS (https://compass-climate.eu/)
Historical (1850-2023) GDP per capita at national level was compiled or estimated from many sources in COMPASS D3.1 [1] and multiplied by estimated mid-year population (see Population — National (ISIMIP4)”). Future national GDP (2025-2100) was extrapolated from 2020 with gap-filled SSP v3.2 data [2], and 2024 interpolated between 2023 and 2025.
Input data, code and documentation (including detailed sources) is available on Zenodo [1] and will be further documented in a forthcoming journal publication.
