VJ102IMG: VIIRS/JPSS1 375m Resolution Swath Imagery

NASA's VIIRS/JPSS1 sensor provides calibrated radiance data across five spectral bands at a 375-meter nadir resolution. These bands cover wavelengths from 0.6 µm to 12.4 µm, capturing visible, near-, shortwave-, mediumwave-, and longwave-infrared radiation. Each data granule represents a nominal 6-minute observation swath, contrasting with the 5-minute duration of MODIS L1B products.

Use Cases

• Monitoring wildfire hotspots based on thermal emissive band (TEB) data.
• Analyzing cloud properties and sea surface temperature using calibrated radiance across multiple infrared wavelengths.
• Assessing vegetation health and land cover change with reflective solar band (RSB) data.
• Calibrating and validating other satellite sensors using the geolocated radiance and reflectance data.

Strengths

• Provides data from five distinct spectral bands with a specific 375-meter spatial resolution at nadir.
• Includes calibrated and geolocated radiance/reflectance data alongside quality flags and metadata.
• Data is produced by NASA, a highly authoritative source for Earth observation.

Limitations

• Key metadata such as specific column names, dataset size, and row counts are not provided across any source.
• License information is inconsistent, with one source specifying 'other-license-specified' and another providing no license.
• The 'last updated' date of 2026-04-09 appears to be a future date, indicating potential metadata errors.
