Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/esrogss/aerdb_l2g_geoleo_merged.001
The Level-2G (L2G) Geostationary Earth Orbit (GEO)-Low-Earth Orbit (LEO) Merged Deep Blue Aerosol 0.25 x 0.25-degree Gridded dataset is part of a 12-product suite produced by an Earth Science Research from Operational Geostationary Satellite Systems (ESROGSS)-funded project.
Description
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 as summarized in the following table: | Platform | Instrument | Temporal Cadence | Spatial Res. | Product | | :-------: | :----------: | :------------------: | :-----------: | :-------: | | GOES-16 | Advanced Baseline Imager | 30 Min. | 10 km | AERDB_L2_ABI_G16 | | GOES-17 | Advanced Baseline Imager | 30 Min. | 10 km | AERDB_L2_ABI_G17 | | Himawari-8 | Advanced Himawari Imager | 30 Min. | 10 km | AERDB_L2_AHI_H08 | | GOES-16 | Advanced Baseline Imager | Daily | 1˚ x 1˚ | AERDB_D3_ABI_G16 | | GOES-17 | Advanced Baseline Imager | Daily | 1˚ x 1˚ | AERDB_D3_ABI_G17 | | Himawari-8 | Advanced Himawari Imager | Daily | 1˚ x 1˚ | AERDB_D3_AHI_H08 | | GOES-16 | Advanced Baseline Imager | Monthly | 1˚ x 1˚ | AERDB_M3_ABI_G16 | | GOES-17 | Advanced Baseline Imager | Monthly | 1˚ x 1˚ | AERDB_M3_ABI_G17 | | Himawari-8 | Advanced Himawari Imager | Monthly | 1˚ x 1˚ | AERDB_M3_AHI_H08 | | **Multiple*** | **ABI, AHI, VIIRS, MODIS*** | **30 Min.** | **0.25˚ x 0.25˚** | **AERDB_L2G_GEOLEO_Merged** | | Multiple* | ABI, AHI, VIIRS, MODIS* | Daily | 1˚ x 1˚ | AERDB_D3_GEOLEO_Merged | | Multiple* | ABI, AHI, VIIRS, MODIS* | Monthly | 1˚ x 1˚ | AERDB_M3_GEOLEO_Merged | \* includes G16-ABI, G17-ABI, H08-AHI, SNPP-VIIRS, NOAA20-VIIRS, Terra MODIS & Aqua MODIS Each L2G GEO-LEO Merged Deep Blue Aerosol product contains gridded Aerosol Optical Thickness (AOT) at 550 nm reference wavelength, derived from seven merged GEO-LEO AOT layers (G16-ABI, G17-ABI, H08-AHI, SNPP-VIIRS, NOAA20-VIIRS, Terra MODIS and Aqua MODIS) and from each of the individual (three GEO and four LEO) instrument sources.
Each L2G aggregated datafile is spatially comprised of a 0.25˚ x 0.25˚ horizontal grid that exists for every 30 minutes. This represents a 30-minute Deep Blue best-estimate AOT from each of the seven sources besides an error-weighted merged AOT layer. This first release of these products spans from May 2019 through April 2020 with a potential to generate additional temporal coverage in the future.
