VJ102MOD: VIIRS Level-1B Calibrated Radiance Swaths

NASA's VIIRS instrument on the JPSS1 satellite provides moderate-resolution multispectral imagery of Earth. The dataset contains calibrated radiance and reflectance data across sixteen spectral bands, ranging from visible to longwave infrared wavelengths, with a spatial resolution of 750 meters at nadir. Each data granule covers a nominal temporal duration of 6 minutes.

Use Cases

• Atmospheric correction of satellite imagery based on calibrated radiance data across 16 spectral bands.
• Land surface temperature retrieval using the five thermal emissive bands (TEB).
• Vegetation index calculation (e.g., NDVI) using the eleven reflective solar bands (RSB).
• Fire detection and monitoring based on mediumwave- and longwave-infrared sensitivity.
• Cloud property analysis using geolocated radiance and quality flags.

Strengths

• Provides data across 16 spectral bands, from 0.402 µm to 12.49 µm, covering visible, near-, shortwave-, mediumwave-, and longwave-infrared wavelengths.
• Offers a spatial resolution of 750 meters at nadir, with 16 detectors per band providing detailed along-track sampling.
• Includes calibrated and geolocated radiance and reflectance data, quality flags, and granule- and collection-level metadata.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided across any platform.
• The listed last update date of 2026-04-09 is in the future, indicating a potential metadata error or placeholder value.
• The license is ambiguously listed as 'other-license-specified' without further details.
