Suomi-NPP VIIRS: Global Vegetation and Sea Surface Temperature

VIIRS, the successor to MODIS, collects data across 22 spectral bands from 412 nm to 12 μm at resolutions of 375m and 750m. Its global binned data provides sea surface temperature (SST) and normalized difference vegetation index (NDVI) products for environmental monitoring. Researchers use these to track marine heatwaves, detect ocean fronts, and analyze vegetation health over time.

Use Cases

• Monitoring marine heatwaves and ocean fronts based on sea surface temperature (sst) data.
• Driving ecosystem and habitat models by pairing SST with chlorophyll-a and other ocean color variables.
• Analyzing vegetation health and trends over time using the normalized difference vegetation index.
• Providing boundary conditions for biogeochemical and climate analyses based on global SST fields.

Strengths

• Data originates from the VIIRS instrument on the Suomi-NPP satellite, a joint NASA-NOAA program launched in October 2011.
• Instrument provides 22 spectral bands with high spatial resolution (375m and 750m at nadir).
• Dataset is the successor to MODIS for Earth science data product generation, indicating a proven lineage.

Limitations

• Column names and specific row counts are not provided by any source, limiting understanding of data structure.
• Conflicting metadata: one source lists 'other-license-specified' while another shows no license information.
• Sea surface temperature data is noted as sensitive to clouds, aerosols, and diurnal warming, requiring careful analysis.
