ABoVE: NDVI and Trends for Alaska's North Slope, 2000-2015

The north slope of Alaska, USA, is covered by this dataset, which provides the average Normalized Difference Vegetation Index (NDVI) at 1-km resolution for each growing season from 2000 to 2015, along with trends for the period. It presents growing-season averages and trends derived from MODIS satellite data and predicted by the Coupled Carbon and Nitrogen (CCaN) model. The dataset was produced by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling vegetation productivity changes based on NDVI trends from 2000 to 2015.
• Comparing satellite-derived vegetation indices with process-based model predictions based on the CCaN model outputs.
• Analyzing spatial patterns of greening or browning on the North Slope of Alaska based on 1-km resolution NDVI data.
• Calibrating or validating ecological models using the MODIS- and CCaN-derived NDVI averages.

Strengths

• Provides 16 years of continuous data from 2000 to 2015.
• Offers 1-km spatial resolution for detailed regional analysis.
• Includes data from two distinct sources: MODIS satellite observations and the CCaN process-based model.
• Focuses on the ecologically sensitive North Slope of Alaska region.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific North Slope region.
