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.
