VJ201_NRT: VIIRS/JPSS2 Raw Radiance and Telemetry Swaths

VIIRS/JPSS2 Raw Radiances in Counts 6-Min L1A Swath NRT contains unpacked, raw science, calibration, and engineering data from the VIIRS instrument. The product includes extracted ephemeris and attitude data from spacecraft diary packets, plus raw ADCS and bus-critical spacecraft telemetry. Users can download the VIIRS Level 1 Product User's Guide for detailed documentation.

Use Cases

• Calibration validation based on raw sensor counts and engineering data.
• Attitude and orbit determination based on extracted ephemeris and attitude data.
• Instrument health monitoring based on raw spacecraft telemetry.
• Level 1B product generation based on unpacked raw VIIRS science data.

Strengths

• Near Real Time (NRT) availability suggests rapid data delivery.
• Cross-platform presence on datagov and nasa_earthdata indicates established importance.
• Product documentation is explicitly referenced and available.

Limitations

• Metadata completeness is low: column names, size, row counts, and author are unknown.
• License information is inconsistent: 'other-license-specified' on datagov vs 'None' on nasa_earthdata.
• Last updated dates conflict: 2026-04-09 on datagov vs 2025-04-13 on nasa_earthdata.
