VJ202MOD_NRT: VIIRS/JPSS2 Satellite Radiance Imagery at 750m Resolution

Global satellite imagery from the JPSS-2/NOAA-21 platform provides calibrated radiance and reflectance data across 16 spectral bands. The product contains 3232 lines by 3200 pixels per image, with a nominal temporal duration of 6 minutes per swath. It is derived from NASA VIIRS L1A raw radiances and includes quality flags and metadata.

Use Cases

• Monitoring land surface temperature changes based on thermal emissive band (TEB) data
• Analyzing vegetation health and reflectance based on reflective solar bands (RSB)
• Developing computer vision models for cloud detection and classification based on calibrated radiance imagery
• Conducting time-series analysis of environmental phenomena based on 6-minute temporal swaths

Strengths

• Provides data across 16 spectral bands ranging from 0.402 µm to 12.49 µm wavelengths
• Offers a spatial resolution of 750 meters at nadir
• Includes calibrated radiance, reflectance, quality flags, and metadata
• Image dimensions are 3232 lines by 3200 pixels per swath

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
