VJ102MOD_NRT: VIIRS/JPSS1 Satellite Imagery Swath

Near Real Time data from the VIIRS sensor on the JPSS1 satellite, processed in 6-minute temporal granules. The dataset contains calibrated radiances and reflectances from sixteen moderate-resolution bands, with wavelengths from 0.402 to 12.49 microns covering visible, near-infrared, and thermal infrared spectra. Each band has a spatial resolution of 750 meters at nadir and includes quality flags and geolocation data.

Use Cases

• Monitoring land surface temperature and thermal anomalies based on thermal emissive band (TEB) data.
• Assessing vegetation health and ocean color using reflective solar bands (RSB) in visible and near-infrared wavelengths.
• Detecting and tracking aerosol plumes or wildfire smoke across a 750m resolution swath.
• Providing input radiance data for downstream atmospheric and environmental Level 2 retrieval algorithms.

Strengths

• Provides calibrated, geolocated radiance data from a well-documented NASA sensor (VIIRS).
• Covers a broad spectral range with 16 specific bands, including 11 reflective solar and 5 thermal emissive bands.
• Offers Near Real Time (NRT) availability for time-sensitive applications.
• Has a defined spatial resolution of 750 meters at nadir for its moderate-resolution bands.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided by any source.
• Conflicting wavelength ranges are reported (0.402-12.49 microns vs. 0.412-12.1 microns).
• License information is inconsistent, listed as 'other-license-specified' on one platform but absent on others.
