Boreal Forest Vegetation Greenness Trends from Landsat, 1985-2019

Circum-hemispheric boreal forest biome data between 45 to 70 degrees north provides interannual trends in annual maximum vegetation greenness from 1985 to 2019 for about 100,000 sample locations. The dataset, from the National Aeronautics and Space Administration, uses an ensemble of spectral vegetation indices derived from Landsat products at 300 m resolution. It includes raster data in GeoTIFF format and trend data in CSV format, with uncertainty estimates from Monte Carlo simulations.

Use Cases

• Modeling climate-driven biome shifts based on multi-decadal greenness trends.
• Analyzing vegetation response to warming based on spectral vegetation indices (NDVI, EVI2, kNDVI, NIRv).
• Assessing ecological change in undisturbed boreal areas based on data stratified by Ecological Land Unit.
• Validating remote sensing products based on Landsat-derived time series from 1985-2019.

Strengths

• Covers the circum-hemispheric boreal forest biome between 45 to 70 degrees north.
• Analyzes about 100,000 random sample locations.
• Provides a 34-year time series from 1985 to 2019.
• Uses an ensemble of four spectral vegetation indices and includes Monte Carlo uncertainty estimates.

Limitations

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