Haze, dust and smoke in the air (GOES-17)

GOES17 ABI Deep Blue Aerosol L2
atmosphere NASA LAADS Level 2 netCDF-4
In plain English

What it measures. Measures airborne particles such as dust, smoke, and haze over a full Earth disk, using the 'Deep Blue' method tuned for bright land surfaces.

How it's made. Derived every 30 minutes from the ABI imager on the GOES-17 geostationary weather satellite, aggregated to roughly 1 km pixels.

How & where you'd use it. Because it watches the same region continuously, it lets researchers follow how haze and smoke build and move through the day, with current files covering May 2019 to April 2020.

Official description

The ABI G17 Deep Blue Aerosol 10-Min L2 Full Disk product, short-name AERDB_L2_ABI_G17 is produced every 30 minutes and contains full-disk observation data. The L2 data products comprise 10 x 10 native GEO pixels. Each spectral band with 0.5 km or 2 km resolution is downscaled or upscaled to a nominal ~1 km horizontal pixel size in the production process. To distinguish them from native instrument pixels, these 10 x 10 aggregated pixels are also called retrieval pixels. Therefore, the L2 products’ image dimensions are roughly 10 km x 10 km at the sub-satellite point and are larger away from that point because of the combined effects of the sensor’s scanning geometry and Earth’s curvature. This first release of these products spans from May 2019 through April 2020 with a potential to generate additional temporal coverage in the future. The Level-2 (L2) Advanced Baseline Imager (ABI) Geostationary Operational Environmental Satellite-17 (GOES-17) Deep Blue Aerosol Full-Disk dataset is part of a 12-product suite produced by an Earth Science Research from Operational Geostationary Satellite Systems (ESROGSS)-funded project. The 12 products in this project include nine derived from three Geostationary Earth Observation (GEO) instruments and three from merged data from GEO and Low-Earth Orbit (LEO) instruments. The AERDB_L2_ABI_G17 product, in netCDF4 format, contains 51 Science Data Set (SDS) layers.
