SNPP VIIRS AER_DBDT_D10KM_L3_VIIRS_SNPP: Global Daily Aerosol Data

Global satellite data provides daily, high-resolution (0.1 x 0.1 degree) Aerosol Optical Depth (AOD) measurements from 2012-03-04 to the present. The dataset combines retrievals from the Deep Blue and Dark Target algorithms on the Suomi NPP satellite's VIIRS instrument. It includes averaged AOD values, standard deviation, pixel count, and average sensor zenith angle for quality filtering.

Use Cases

• Monitoring regional air pollution trends based on daily, global AOD measurements.
• Validating and improving atmospheric models using high-resolution, algorithm-combined aerosol data.
• Studying long-term aerosol transport and climate impacts using the multi-year time series from 2012 onward.
• Filtering data for specific research applications using the provided quality metrics like standard deviation and sensor zenith angle.

Strengths

• Provides a long, consistent time series with global coverage starting from March 4, 2012.
• Offers high spatial resolution (0.1 x 0.1 degree) for detailed regional analysis.
• Combines two established retrieval algorithms (Deep Blue and Dark Target) to improve data coverage and reliability.
• Includes quality assurance metrics like standard deviation and pixel count for each averaged value.

Limitations

• Specific column names and the exact data structure are not detailed in the provided metadata.
• One source lists a last update date in the future (2026-04-09), indicating potential metadata freshness issues.
• The dataset's size and row count are unknown across all sources.
