Permafrost Thaw and Distribution Across the Tibetan Plateau, 1980-2100

1980-2019 bias-corrected climate data and simulated permafrost distribution for the Tibetan Plateau, with projections to 2100 under three SSP scenarios. The dataset includes permafrost table depth maps and a shapefile for 10 sub-regions. It was created by Taihua Wang of Tsinghua University.

Use Cases

• Modeling historical permafrost distribution based on bias-corrected temperature and precipitation data.
• Projecting future permafrost extent and table depth under SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios.
• Analyzing changes in near-surface permafrost defined as areas with table depth less than 3 meters.
• Regional analysis of permafrost changes using the provided shapefile for 10 Tibetan Plateau sub-regions.

Strengths

• Includes historical data for 1980-2019 and projections for 2060 and 2100.
• Covers three Shared Socioeconomic Pathway (SSP) scenarios: SSP1-2.6, SSP2-4.5, and SSP5-8.5.
• Uses ERA5 reanalysis data bias-corrected with observations from 97 meteorological stations.

Limitations

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