The FAA Aviation Weather Research Program's (AWRP) National Ceiling and Visibility Product Development Team (NCV PDT) has developed automated analysis and forecast products describing ceiling and visibility conditions over the continental United States. The NCV analysis product incorporates observational data from both Automated Surface Observing System (ASOS) and Geostationary Operational Environmental Satellite (GOES) imagers. At present, GOES imager data are used to outline the extent of clear and cloudy conditions, while ASOS data is used to determine cloud ceiling height and visibility. This paper will discuss the use of cloud masking, related GOES products, interpolation techniques, and confidence in the analysis product's current system methodology, performance and future development.
