NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Land Surface Bidirectional Reflectance Factor (BRF)
The GOES-R Advanced Baseline Imager (ABI) Level 2 Bidirectional Reflectance Factor (BRF) products provide spectral land surface reflectance, i.e., a ratio between outgoing radiance at one given direction and incoming radiance at another given direction (same or different from the incoming direction). In this product, the outgoing direction is the direction of the satellite view, while the incoming direction is the direction of solar illumination. The BRF is produced at the following wavelengths: 0.47 µm, 0.64 µm, 0.86 µm, 1.61 µm, and 2.26 µm, corresponding to bands 1, 2, 3, 5, 6. The product includes associated data quality flags and percentage of each flag value, mean, maximum, minimum, and standard deviation of BRF of each band. The ABI BRF provides spatial and temporal continuous surface reflectance information. The product image is provided at 2 km resolution on the ABI fixed grid for Full Disk, CONUS, and Mesoscale coverage regions from GOES East and West.

NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Land Surface Albedo (LSA)
공공데이터포털
The GOES-R Advanced Baseline Imager (ABI) Level 2 Land Surface Albedo (LSA) as defined as the ratio between outgoing and incoming irradiance at the earth's surface. The LSA is a shortwave broadband blue-sky albedo over wavelengths between 0.4 and 3.0 µm. Besides the blue-sky broadband shortwave albedo, the LSA algorithm also generates spectral land surface reflectance as byproducts. The frequent temporal refreshment, fine spectral resolution and large spatial coverage make ABI a unique data source for mapping LSA. The Land Surface Albedo product image is provided at 2 km resolution on the ABI fixed grid for Full Disk, CONUS, and Mesoscale coverage regions from GOES East and West.

NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Fog/Low Stratus (FLS)
공공데이터포털
The GOES-R Advanced Baseline Imager (ABI) Fog/Low Stratus (FLS) products contain estimates of low cloud/fog thickness and probabilities of reduced aviation visibility for Marginal Visual Flight Rules, Instrument Flight Rules, and Low Instrument Flight Rules from the Advanced Baseline Imager (ABI) instrument. Also, the FLS probability products include information when higher clouds mask the satellite view of low clouds, and screens out regions of elevated stratus to highlight areas where the cloud ceiling likely meets the categorical thresholds.

NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Cloud Cover Layers (CCL)
공공데이터포털
The GOES-R Advanced Baseline Imager (ABI) Cloud Cover Layers (CCL) product contains estimates of cloud fraction between predefined atmospheric levels, as well as, the total cloud fraction at a specified spatial resolution. There are five flight levels of cloud fractions classified as low, middle, and high clouds. The 5 layers defined in feet are: surface to 5000, 5000 to 10000, 10000 to 18000, 18000 to 24000, and 24000 to top of the atmosphere. The horizontal spatial resolution of the products are 10km for full disk and CONUS, and 4km for mesoscale.
