ABoVE: Maximum NDVI for Northern Alaska and Yukon, 2002-2017

2002-2017 annual maximum Normalized Difference Vegetation Index (NDVI) at 1-km resolution over northern Alaska and the Yukon Territory, derived from MODIS satellite data. The dataset includes a long-term 16-year maximum NDVI product, aggregated from 250-meter pixel observations collected during each growing season. It was produced by the National Aeronautics and Space Administration.

Use Cases

• Modeling vegetation productivity and phenology based on annual maximum NDVI values.
• Analyzing long-term greening or browning trends in the Arctic based on the 16-year time series.
• Mapping land cover and ecosystem boundaries based on spatial patterns in maximum NDVI.
• Calibrating or validating ecological models with satellite-derived vegetation index data.

Strengths

• Provides a consistent 16-year time series from 2002 to 2017.
• Data is derived from MODIS Collection 6 products, a standard satellite data source.
• Includes both annual maximum values and a synthesized 16-year maximum product.

Limitations

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