VJ202MOD: VIIRS/JPSS2 Satellite Radiance Data at 750m Resolution

NASA Visible Infrared Imaging Radiometer Suite (VIIRS) calibrated radiance data from the JPSS-2/NOAA-21 satellite. The product comprises sixteen moderate-resolution bands with a spatial resolution of 750 meters at nadir, including eleven reflective solar bands and five thermal emissive bands. Data includes calibrated radiance and reflectance, quality flags, and metadata, with reprocessing updates for the reflective solar bands.

Use Cases

• Monitor land surface temperature and thermal anomalies based on the five thermal emissive bands (TEB).
• Analyze vegetation health and ocean color using the eleven reflective solar bands (RSB).
• Perform geospatial analysis of environmental features using the 750-meter resolution calibrated radiances.
• Develop algorithms for atmospheric correction and cloud detection using the calibrated radiance and quality flags.

Strengths

• Data includes sixteen spectral bands with a spatial resolution of 750 meters at nadir.
• Product contains calibrated radiance and reflectance data, quality flags, and granule-level metadata.
• Reprocessing includes calibration updates for the eleven reflective solar bands.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or temporal bias inherent to the satellite's polar orbit.
