Siberian Larch Biomass and Fire Scar Maps for Kolyma Basin

NASA's dataset provides 30-meter resolution maps of Cajander larch aboveground biomass circa 2007 and perimeters for 116 forest fires from 1966-2007. The data covers approximately 100,000 square kilometers of the Kolyma River Basin in northeastern Siberia, Russia. It combines biomass estimates with a multi-decadal fire history for a key boreal forest region.

Use Cases

• Modeling carbon stocks in Cajander larch-dominated boreal forests using the aboveground biomass (AGB) layer.
• Analyzing the spatial relationship between historical fire perimeters (1966-2007) and contemporary forest biomass.
• Studying long-term fire regime impacts on Siberian forest structure and recovery over a 41-year period.
• Calibrating or validating remote sensing biomass algorithms with ground-referenced estimates for a specific tree species.

Strengths

• Provides species-specific (Cajander larch) biomass estimates at a high 30-meter spatial resolution.
• Integrates two key data products: biomass maps and a 116-fire perimeter database spanning 41 years (1966-2007).
• Covers a large, contiguous study area of approximately 100,000 square kilometers in northeastern Siberia.

Limitations

• Specific column names and data structure are not documented on the provided platforms.
• There is a conflict in the 'last updated' metadata: datagov lists 2026-03 12, while nasa_earthdata lists 2007-07-26.
• The license is specified as 'other-license-specified' without explicit details on reuse terms.
