Modeled Permafrost Active-Layer Depth in Russia

Modeled active-layer depth values in centimeters cover Russia from 50°N to 80°N and 60°E to 160°E. The dataset provides depth calculations for both current climate conditions and a projected 2050 climate scenario. It is authored by NSIDCV0 and available in tab-delimited ASCII text and GIF image formats.

Use Cases

• Comparing current and projected 2050 active-layer depths using the modeled depth values.
• Analyzing spatial patterns of permafrost thaw across Russian latitudes and longitudes.
• Validating other permafrost or climate models with the provided depth calculations.
• Creating visualizations or maps from the geospatial data points and GIF images.

Strengths

• Provides data for two distinct climate scenarios: current conditions and a 2050 projection.
• Covers a specific, large geographic region spanning 20 degrees of latitude and 100 degrees of longitude.
• Includes both numerical data (tabular text files) and visual representations (GIF maps).

Limitations

• Key metadata such as row count, column names, and exact data size are unavailable from all sources.
• Conflicting last updated dates exist: one source reports 2003-03-04, while others report 2026-03-13.
