AERDB_M3_VIIRS_NOAA20: Monthly Aerosol Data Grid

VIIRS/NOAA20 Deep Blue Level 3 monthly aerosol data provides a 1x1 degree gridded product derived from daily satellite observations. The dataset contains 45 Science Data Set layers in netCDF format, with monthly aggregation requiring at least 3 valid days of data per grid element. Its record starts from January 5th, 2018.

Use Cases

• Analyzing monthly aerosol optical depth trends based on the 45 SDS layers.
• Mapping global aerosol distribution using the 1x1 degree gridded data.
• Validating atmospheric models with satellite-derived aerosol statistics.
• Studying long-term aerosol changes from the January 2018 start date.

Strengths

• Contains 45 distinct Science Data Set layers for detailed analysis.
• Provides a consistent monthly record starting from a specific date (January 5, 2018).
• Aggregation algorithm requires at least 3 valid days to ensure data quality per grid element.

Limitations

• Column names and dataset size are unspecified across all platforms.
• License details are unclear, listed only as 'other-license-specified'.
• Metadata completeness is low, with missing author, row count, and size information.
