NOAA-21 VIIRS: Global Binned Normalized Difference Vegetation Index Data

The 2022.0 version of Level-3 global binned NDVI data from the Visible and Infrared Imager/Radiometer Suite (VIIRS) instrument. VIIRS is flown on the Joint Polar Satellite System series, including the Suomi NPP spacecraft launched in October 2011, and is the successor to MODIS for Earth science products. The instrument has 22 spectral bands, including 16 moderate-resolution bands (750m at nadir), 5 image-resolution bands (375m), and one day-night band.

Use Cases

• Monitoring global vegetation health and phenology based on the Normalized Difference Vegetation Index (NDVI).
• Analyzing land cover change and agricultural productivity using multi-spectral bands ranging from 412 nm to 12 nm.
• Comparing vegetation trends with MODIS data, as VIIRS is described as its successor.
• Conducting diurnal environmental studies leveraging the instrument's day-night band (DNB).

Strengths

• Data originates from the VIIRS instrument, which has 22 spectral bands providing detailed spectral information.
• Provides global coverage as a Level-3 binned product, likely aggregating observations over space and time.
• Platform tags and description specify its relevance to Earth Science, Vegetation, and the Biosphere.

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 may reflect geographic or temporal bias inherent to the satellite's polar-orbiting coverage pattern.
