SNPP VIIRS+CrIS Fusion: Infrared Radiance at 750m Resolution

Version 2.0 of this NASA product fuses VIIRS and CrIS sensor data to construct infrared absorption band radiances at a 750-meter spatial resolution. The dataset is stored in 6-minute NetCDF4 granules and includes improvements for scanline quality control, collocation accuracy, and artifact correction over warm, dry surfaces. Its spectral bands are designed to provide continuity with legacy HIRS and MODIS instruments for cloud, moisture, and atmospheric applications.

Use Cases

• Continuity analysis for cloud and moisture products based on legacy HIRS and MODIS spectral bands.
• Atmospheric sounding and temperature retrieval using the fused infrared radiance and brightness temperature look-up tables.
• Quality assessment of satellite data fusion techniques, leveraging the improved scanline and collocation checks in v2.0.
• Studying surface artifacts in water vapor channels over warm, dry regions, as addressed by the v2.0 correction.

Strengths

• Provides a specific 750-meter spatial resolution, matching the native VIIRS M-band.
• Represents a v2.0 collection with documented improvements to data salvage, collocation, and artifact correction.
• Data is structured in compressed NetCDF4 files, a standard format for scientific geospatial data.

Limitations

• Column names and specific data structure are not provided in the available metadata.
• Dataset size and row counts are unknown across all sources.
• License information is inconsistently reported as 'other-license-specified' or null.
