Arctic Vegetation and Snow Depth Maps for Alaska and Canada

Eleven sites across the North Slope of Alaska and the Northwest Territories of Canada provide vegetation cover maps, Normalized Difference Vegetation Index (NDVI) maps, snow depth, and thaw depth data. This dataset was created for a biocomplexity project, forming transects across climate and latitudinal gradients. The data is hosted by ORNL_CLOUD, but the specific collection date range is not provided.

Use Cases

• Analyzing vegetation cover changes across Arctic climate gradients using site-specific maps.
• Correlating Normalized Difference Vegetation Index (NDVI) values with latitudinal position from Inuvik to Isachsen.
• Investigating relationships between snow depth measurements and active layer thaw depths at monitoring sites.
• Comparing biogeophysical conditions between acidic and nonacidic tundra sites at Sagwon.

Strengths

• Data covers a transect of 11 specific field sites across two countries, enabling gradient analysis.
• Includes multiple synchronized data layers: vegetation cover, NDVI, snow depth, and thaw depth.

Limitations

• Column names and specific row or file counts are unknown from all sources.
• Sources conflict on the last updated date: one states 2012-12-31, while others state 2026-03-13.
