NOAA-20 VIIRS: Global Binned Normalized Difference Vegetation Index Data

The Visible and Infrared Imager/Radiometer Suite (VIIRS) instrument provides global vegetation index data from the NOAA-20 satellite. This dataset is the successor to MODIS for Earth science products and contains data from 22 spectral bands, including 16 moderate-resolution and 5 image-resolution bands. The data is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Monitor global vegetation health and phenology based on the Normalized Difference Vegetation Index (NDVI).
• Analyze land cover changes and agricultural productivity using multi-spectral remote sensing data.
• Model climate and ecosystem interactions based on data from the VIIRS instrument's 22 spectral bands.
• Compare vegetation trends with historical MODIS data, as VIIRS is described as its successor.

Strengths

• Data originates from the VIIRS instrument, which has 22 spectral bands providing detailed spectral information.
• Includes 16 moderate-resolution bands (750m at nadir) and 5 image-resolution bands (375m) for varied analysis scales.
• Produced by the authoritative National Aeronautics and Space Administration (NASA).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data is provided in specialized BIN and ISO file formats, which may require specific tools for processing.
