XAERDT_L2_ABI_G17: GOES-17 Aerosol Data at 10 km Resolution

NASA's MEaSUREs program produced this Level 2 aerosol dataset from the GOES-17 satellite's Advanced Baseline Imager. It contains 45 Science Data Set layers, including 8 for geolocation and 37 for geophysical parameters like Aerosol Optical Depth. The product provides full-disk observations at a 10-minute cadence and 10-km spatial resolution, covering the GOES-West operational period from February 2019 to January 2023.

Use Cases

• Tracking aerosol plume movement and evolution based on 10-minute geostationary observations.
• Validating and intercomparing aerosol retrievals across seven GEO and LEO satellite sensors.
• Analyzing diurnal cycles of atmospheric particulates using the high-temporal-resolution data.
• Assimilating near-real-time Aerosol Optical Depth measurements into air quality forecast models.

Strengths

• High temporal resolution with a 10-minute full-disk cadence, yielding about 144 granules per day.
• Part of a cross-platform project ensuring consistent science maturity across 7 sensor/platform combinations.
• Contains a detailed structure of 45 Science Data Set layers for comprehensive geophysical analysis.

Limitations

• Metadata completeness is low; specific column names, row counts, and file sizes are not provided on any platform.
• The temporal coverage is explicitly limited to the GOES-17 operational period, ending in January 2023.
• Conflicting license information exists between 'other-license-specified' and 'None' across the sources.
