VJ202IMG: JPSS-2 VIIRS Satellite Imagery at 375m Resolution

VJ202IMG is a Level-1B calibrated radiance product from the VIIRS instrument aboard the NOAA-21 (JPSS-2) satellite. It provides five image-resolution bands at 375-meter nadir resolution, covering visible, near-infrared, shortwave-, mediumwave-, and longwave-infrared wavelengths from 0.6 µm to 12.4 µm. The dataset includes three reflective solar bands and two thermal emissive bands, offering finer spatial detail than the instrument's moderate-resolution and day-night bands.

Use Cases

• Monitoring land surface temperature and thermal anomalies based on thermal emissive band data.
• Analyzing vegetation health and land cover using reflective solar bands in the visible and near-infrared spectrum.
• Detecting and tracking active fires or volcanic hotspots from mediumwave- and longwave-infrared signals.
• Creating high-resolution true-color or false-color composite imagery for visual analysis of Earth's surface.

Strengths

• Provides high-resolution imagery at 375 meters per pixel, which is twice as fine as the sensor's moderate-resolution bands.
• Covers a broad spectral range from 0.6 µm to 12.4 µm across five distinct bands sensitive to different physical phenomena.
• Includes calibrated radiance values, suitable for quantitative scientific analysis.

Limitations

• Key metadata such as row count, file size, and specific column structure is unavailable across all sources.
• Sources conflict on the presence of tags and some metadata fields, indicating potential inconsistencies in platform records.
• The dataset's spatial coverage is not explicitly defined, limited to the satellite's swath path.
