VIIRS Cirrus Reflectance Swath Data at 750-Meter Resolution

The VIIRS/Suomi-NPP Cirrus Reflectance 6-Min Swath 750m is a Level-2 satellite product generated at 750-meter spatial resolution at nadir. It uses a series of visible and infrared threshold tests to assess confidence in an unobstructed Earth surface view and provides an indication of scene shadows. The dataset is produced by the LAADS organization and was last updated in March 2026.

Use Cases

• Confidence assessment for unobstructed Earth surface views using visible and infrared threshold tests.
• Detection of shadows affecting satellite scenes.
• Identification of cirrus cloud reflectance properties from radiance data.
• Quality assurance flagging based on input radiance completeness and accuracy.

Strengths

• Provides radiometrically-accurate radiances required for precise atmospheric analysis.
• Offers a high spatial resolution of 750 meters at nadir for detailed swath imagery.
• Algorithm employs multiple visible and infrared consistency tests for reliable confidence specification.

Limitations

• Specific row counts, column names, and dataset size are not provided by any source.
• Sources conflict on license details, with some listing 'other-license-specified' and others 'None'.
• Holes in the Cloud Mask product will appear wherever input radiances are incomplete or of poor quality.
