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. It is derived from NASA VIIRS L1A raw radiances and includes calibrated radiance and reflectance data, quality flags, and metadata.
Use Cases
- Monitoring land surface temperature based on thermal emissive band data.
- Analyzing vegetation health and ocean color using reflective solar band radiances.
- Developing cloud detection algorithms based on calibrated radiance and quality flags.
- Conducting atmospheric research using data from bands sensitive to visible and infrared wavelengths.
Strengths
- Provides data from sixteen spectral bands ranging from 0.402 µm to 12.49 µm.
- Offers a spatial resolution of 750 meters at nadir for all moderate-resolution bands.
- Includes calibrated and geolocated radiance and reflectance data with quality flags.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
Provenance
