Fog and Low Stratus - Fog Detection
The Fog and Low Status (FLS) uses GOES ABI L1B data to quantitatively identify clouds that produce Marginal Visual Flight Rule (MVFR), Instrument Flight Rule (IFR), and Low Instrument Flight Rule (LIFR) conditions. It provides the probability that MVFR/IFR/LIFR conditions are present, along with an estimate of the geometric cloud thickness. FLS products cover the Full Disk, CONUS, and Alaska regions.

JPSS Risk Reduction Products - Clouds
The JPSS‑RR Clouds product is an experimental, VIIRS-based satellite dataset for cloud detection and classification. Developed to test and mature risk-reduction algorithms, it offers layered views of cloud cover over time and space—helping improve future JPSS operational cloud-monitoring tools.
