VJ202IMG_NRT: VIIRS/JPSS2 375m Resolution Satellite Imagery

NASA's VIIRS/JPSS2 Imagery Resolution 6-Min L1B Swath 375m Near Real Time (NRT) product provides calibrated radiance and reflectance data from five image-resolution bands. The dataset includes three reflective solar bands and two thermal emissive bands, with a spatial resolution of 375 meters at nadir and a nominal temporal duration of 6 minutes per granule. Each data granule has image dimensions of 6464 lines by 6400 pixels, covering wavelengths from 0.6 µm to 12.4 µm.

Use Cases

• Monitoring wildfire hotspots and thermal anomalies based on thermal emissive band data.
• Analyzing cloud properties and aerosol optical depth using calibrated reflectance from reflective solar bands.
• Tracking sea surface temperature and ice cover dynamics from longwave infrared wavelengths.
• Conducting land cover change detection with high-resolution visible and near-infrared imagery.

Strengths

• Provides high-resolution imagery with a 375-meter nadir resolution, twice as fine as the sensor's moderate bands.
• Offers near-real-time (NRT) data availability for time-sensitive applications.
• Covers a broad spectral range from visible to longwave infrared (0.6 µm to 12.4 µm).

Limitations

• Column names and a complete data schema are not provided in the available metadata.
• Conflicting 'last updated' dates exist between sources (2026-04-09 on datagov vs. 2025-04-13 on nasa_earthdata).
• Dataset size and total row counts are unspecified across all platforms.
