Peak Greenness of Canadian Boreal Forest from Landsat, 1984-2011

A 28-year time series of peak greenness (NDVI) and normalized burn ratio (NBR) data for the Canadian boreal forest, derived from Landsat 5 TM imagery. The dataset, provided by NASA, covers 46 selected sites from 1984 to 2011, with data regridded to a 500-meter resolution. Supplemental metadata includes land cover composition and disturbance history for each site.

Use Cases

• Modeling vegetation phenology trends based on the 28-year NDVI time series.
• Assessing forest disturbance and recovery patterns based on the normalized burn ratio (NBR) data.
• Analyzing the relationship between climate gradients and peak greenness across the 46 selected sites.
• Conducting trend analysis on vegetation health at a 500-meter spatial resolution.

Strengths

• 28-year temporal coverage from 1984 to 2011 provides a long-term perspective.
• Data from 46 sites across gradients in climate, tree cover, and disturbance history.
• Includes two derived indices (NDVI and NBR) and supplemental site metadata.

Limitations

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