VJ202IMG_NRT: VIIRS JPSS2 375m Imagery Radiance Swaths

NASA VIIRS/JPSS2 Level-1B calibrated radiance product provides five image-resolution bands at 375-meter nadir resolution. The dataset includes three reflective solar bands and two thermal emissive bands, covering wavelengths from 0.6 µm to 12.4 µm for visible, near-, shortwave-, mediumwave-, and longwave-infrared sensing. Each data granule represents a 6-minute temporal swath with image dimensions of 6464 lines by 6400 pixels, containing calibrated radiance/reflectance, geolocation, quality flags, and metadata.

Use Cases

• Monitoring thermal anomalies like wildfires based on thermal emissive band (TEB) data.
• Analyzing cloud properties and aerosol optical thickness using reflective solar bands (RSB).
• Land cover and vegetation studies leveraging the 375-meter resolution I-bands.
• Near-real-time (NRT) environmental event detection from 6-minute temporal granules.
• Cross-sensor comparison with MODIS products, utilizing the finer spatial resolution.

Strengths

• Provides high spatial resolution with 375-meter nadir resolution, twice as fine as VIIRS moderate bands.
• Covers a broad spectral range from 0.6 µm to 12.4 µm across five distinct I-bands.
• Delivered in near-real-time (NRT), supporting time-sensitive applications.
• Each granule has defined dimensions of 6464 lines by 6400 pixels, providing consistent data structure.

Limitations

• Column names and specific data schema are not provided in the available metadata.
• Conflicting 'last updated' dates (2026-03-12 and 2026-04-09) on datagov create uncertainty about freshness.
• License is ambiguously listed as 'other-license-specified' without explicit terms.
