CLDMSK_L2_VIIRS_NOAA20: Cloud Mask and Spectral Test Results

NOAA-20 satellite data provides a Level 2 cloud mask product at 750-meter spatial resolution. The dataset is derived from the MODIS-VIIRS cloud mask algorithm, designed to sustain long-term records from MODIS and VIIRS satellite heritages. It contains spectral test results for cloud detection over a 6-minute swath.

Use Cases

• Cloud detection and mapping based on spectral test results.
• Climate trend analysis leveraging the long-term continuity with MODIS data.
• Satellite data fusion studies using calibration-adjusted NASA VIIRS L1B inputs.

Strengths

• Provides continuity with long-term MODIS and VIIRS cloud records.
• Offers a nominal spatial resolution of 750 meters.

Limitations

• Column names and data structure are unknown from all sources.
• Metadata completeness is low, with no explicit row counts, file sizes, or author information.
• The term 'MVCM', central to the algorithm description, does not appear in the product's metadata.
