ABI G17 Deep Blue: Daily Aerosol Grid Data

NASA's AERDB_D3_ABI_G17 dataset provides daily Level-3 aerosol optical depth measurements from the GOES-17 satellite's Advanced Baseline Imager. The data is aggregated to a 1x1 degree global grid, with each cell representing the arithmetic mean of at least three quality-filtered retrievals per day. This product contains 48 Science Data Set layers in netCDF4 format and is part of a 12-product suite from the ESROGSS-funded project.

Use Cases

• Tracking daily aerosol optical depth patterns over the GOES-17 field of view based on the 1x1 degree gridded data.
• Analyzing aerosol transport and seasonal variability using the time series from May 2019 to April 2020.
• Validating aerosol models with satellite-derived, quality-assured mean and standard deviation statistics.
• Integrating geostationary aerosol data with low-earth orbit observations as part of the broader ESROGSS product suite.

Strengths

• Data is quality-assured, requiring at least three valid retrievals per grid cell per day.
• Contains 48 distinct Science Data Set layers providing multiple aerosol-related variables.
• Part of a cross-platform, multi-instrument suite (ESROGSS), indicating peer-reviewed methodology.

Limitations

• Initial temporal coverage is limited to one year (May 2019–April 2020), though future extensions are possible.
• Key metadata like row count, file size, and specific column names are unavailable across all sources.
• Conflicting 'last updated' dates (2026-03-13 on datagov vs. 2020-05-01 on nasa_earthdata) create uncertainty about data currency.
