Dataset Overview | National Centers for Environmental Information (NCEI)

NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Fog/Low Stratus (FLS)

ABI-L2-GFLS

GOES-16 Instrument Flight Rule Fog Probability Map

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.

Data Update Frequency	Continual
Purpose	This data is available to the public for a wide variety of uses including scientific research and analysis. FLS may be used to gain more information on cloud decks over data voids. It may also be used as a decision aid for terminal aerodrome forecast preparation. FLS can provide the forecaster confidence information on spatial extent, and help the forecaster convey uncertainty in the Area Forecast Discussion and to NWS core partners (e.g. FAA).
Use Limitations	For a complete set of limitations for this dataset see the Algorithm Theoretical Basis Document (ATBD).

Processor	DOC/NOAA/NESDIS/OSPO > Office of Satellite and Product Operations, NESDIS, NOAA, U.S. Department of Commerce
Processing Steps	The Legacy Vertical Temperature Profile, Legacy Vertical Moisture Profile, Total Precipitable Water, and Derived Stability Indices products are generated by the GOES-R ABI Legacy Atmospheric Profiles ground processing algorithm. The algorithm uses processed NWP model profile data as the first guess and employs a regression retrieval followed by an iterative physical retrieval that utilizes the ground system implementation of the Community Radiative Transfer Model (CRTM) to derive the final product data. The temperature and moisture profiles contain values at 101 standard pressure levels, of which only 54 temperature and 35 moisture pressure levels are actually populated in the retrieval. The 54 temperature levels are from approximately 103 hPa to approximately 1014 hPa. The 35 moisture levels are from 300 hPa to approximately 1014 hPa. The regression retrieval is applied for coverage regions corresponding to local zenith angles to 80 degrees but the physical retrieval is limited to local zenith angles to 67 degrees. The product is generated for 5 x 5 fields of regard from 2 km pixel inputs where the percentage of clear pixels satisfies a 20 percent threshold. Clear sky is determined using clear and probably clear pixels indicated in the temporally coincident intermediate 4-level cloud mask generated by the Cloud Mask algorithm. Total precipitable water from the surface to 300 hPa is derived from the retrieved moisture profile. In addition, the five atmospheric stability indices, CAPE, K-index, Lifted Index, Showalter Index, and Total Totals Index, are derived from the retrieved moisture and temperature profiles. Pixels in the product images with out of range values are assigned the minimum or maximum value in the valid range.
