Historical and SSP-Consistent Gridded GDP and Three-Sector Value Added for China, 2000-2100

This dataset provides linked historical and scenario-conditioned gridded estimates of total GDP and primary, secondary, and tertiary value added for China. The historical product contains annual 500 m rasters for 2000-2023. The future product contains 30-arc-second rasters at five-year intervals for 2025-2100 under SSP1-SSP5. All values are expressed as million constant 2015 USD per grid cell. The release contains 416 GeoTIFFs together with administrative and sector-closure audits, data-source provenance, validity-mask documentation, file inventories, checksums, and a reproducible public workflow. Historical and future product families retain their documented native grids. Numeric zero within the valid-data mask is a legitimate value; areas outside product support are represented through the GDAL validity mask.
