Gridded GDP Projections Compatible with SSPs, 1850–2100 at 1/12-Degree Resolution

Estimated GDP values for 1/12-degree grid cells from 1850 to 2100 at 10-year intervals. The data is produced by downscaling national GDP figures using spatial-economic interactions, urban growth patterns, and geographic data like land cover and road networks. The projections are authored by Daisuke Murakami and colleagues and are compatible with the five Shared Socioeconomic Pathways (SSPs).

Use Cases

• Modeling climate-economy interactions based on SSP-compatible economic scenarios.
• Analyzing long-term spatial economic inequality trends based on gridded GDP projections.
• Downscaling integrated assessment model outputs for regional impact studies based on the described urban growth and spatial interaction methods.
• Projecting future land-use demand by coupling economic and geographic data as mentioned in the description.

Strengths

• Projections span a 250-year period from 1850 to 2100.
• Data is provided at a high spatial resolution of 1/12-degree grid cells.
• Estimates incorporate multiple geographic data sources including land cover and road networks.
• Scenarios are aligned with five established Shared Socioeconomic Pathways (SSPs).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
