VNP02DNB: VIIRS Day/Night Band Satellite Radiance Swaths

NASA's VIIRS/NPP Day/Night Band 6-Min L1B Swath 750 m product (VNP02DNB) provides calibrated panchromatic radiance data at a 750-meter spatial resolution. Its spectral range from 0.5 µm to 0.9 µm enables measurement across a large dynamic range, from quarter-moon illumination to full daylight. The dataset facilitates analysis of night lights and reflected solar or lunar radiation.

Use Cases

• Mapping urban development and energy consumption based on night light emissions.
• Monitoring disaster impacts like power outages from reflected lunar illumination.
• Studiating atmospheric phenomena and cloud properties using calibrated radiance across the day-night cycle.
• Calibrating and validating models of light propagation and surface reflectance.

Strengths

• Data originates from NASA, an authoritative source for satellite earth observation.
• Provides a unique panchromatic band specifically designed for a massive dynamic range from night to day.
• Has a consistent at-nadir spatial resolution of 750 meters across the entire sensor swath.

Limitations

• Column names and detailed data structure are not provided in any source description.
• Metadata on data volume (size/rows) is consistently absent across all platforms.
• License information is inconsistently reported as 'other-license-specified' or null.
