AERDA_D3_VIIRS_MODIS_NRT: Daily Satellite Aerosol Data

NASA's AERDA_D3_VIIRS_MODIS_NRT product provides 24-hour aggregated aerosol optical depth data from four satellite instruments: VIIRS on NOAA-20 and SNPP, and MODIS on Aqua and Terra. It combines Dark Target and Deep Blue retrieval algorithms with consistent Level 3 aggregation and pre-defined QA filtering for near-real-time applications. The dataset is produced daily after all upstream Level 2 data becomes available.

Use Cases

• Evaluating aerosol product performance based on combined Dark Target and Deep Blue retrievals.
• Data assimilation for atmospheric models using near-real-time, quality-filtered Level 3 data.
• Monitoring daily global aerosol optical depth patterns from multiple satellite platforms.
• Benchmarking aerosol retrieval algorithms using the consistent aggregation methodology.

Strengths

• Combines data from four satellite instruments (VIIRS/NOAA-20, VIIRS/SNPP, MODIS/Aqua, MODIS/Terra) for broad coverage.
• Provides near-real-time data with daily (24-hour) temporal resolution.
• Applies consistent Level 3 aggregation and pre-defined QA thresholds for reliability.

Limitations

• Column names and specific data structure are not provided in any source description.
• Conflicting license information: one source lists 'other-license-specified' while another lists 'None'.
• Dataset size and row counts are unknown across all platforms.
