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:\n\n| Platform | Instrument | Temporal Cadence | Spatial Res. | Product |\n| :-------: | :----------: | :------------------: | :-----------: | :-------: |\n| **GOES-16** | **Advanced Baseline Imager** | **30 Min.** | **10 km** | **AERDB_L2_ABI_G16** |\n| GOES-17 | Advanced Baseline Imager | 30 Min. | 10 km | AERDB_L2_ABI_G17 |\n| Himawari-8 | Advanced Himawari Imager | 30 Min. | 10 km | AERDB_L2_AHI_H08 |\n| GOES-16 | Advanced Baseline Imager | Daily | 1\u02da x 1\u02da | AERDB_D3_ABI_G16 |\n| GOES-17 | Advanced Baseline Imager | Daily | 1\u02da x 1\u02da | AERDB_D3_ABI_G17 |\n| Himawari-8 | Advanced Himawari Imager | Daily | 1\u02da x 1\u02da | AERDB_D3_AHI_H08 |\n| GOES-16 | Advanced Baseline Imager | Monthly | 1\u02da x 1\u02da | AERDB_M3_ABI_G16 |\n| GOES-17 | Advanced Baseline Imager | Monthly | 1\u02da x 1\u02da | AERDB_M3_ABI_G17 |\n| Himawari-8 | Advanced Himawari Imager | Monthly | 1\u02da x 1\u02da | AERDB_M3_AHI_H08 |\n| Multiple* | ABI, AHI, VIIRS, MODIS* | 30 Min. | 0.25\u02da x 0.25\u02da | AERDB_L2G_GEOLEO_Merged |\n| Multiple* | ABI, AHI, VIIRS, MODIS* | Daily | 1\u02da x 1\u02da | AERDB_D3_GEOLEO_Merged |\n| Multiple* | ABI, AHI, VIIRS, MODIS* | Monthly | 1\u02da x 1\u02da | AERDB_M3_GEOLEO_Merged |\n\n\\*  includes G16-ABI, G17-ABI, H08-AHI, SNPP-VIIRS, NOAA20-VIIRS, Terra MODIS & Aqua MODIS\n\nEach L2 ABI/GOES-16 product 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\u2019 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\u2019s scanning geometry and Earth\u2019s 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.\n\nEach L2 ABI/GOES-16 datafile contains 51 Science Data Sets (SDS) that include the following:\n\n1.
