Development of FAA National Ceiling and Visibility products: Challenges, strategies and progress
Recent development of an automated ceiling and visibility forecast system for the continental U.S. has utilized expert system methodology to blend numerical and observational inputs in the synthesis of ceiling and visibility analyses and forecasts out to 12 hours. The system makes use of current and historical METAR data, GOES observations, numerical models, MOS and LAMP forecasts, and observations-based ruleset forecasts. As this system matures, a similar approach will be used to provide corresponding analyses and forecasts in Alaska.
This paper outlines recent progress and current functionality of the continental U.S. system. This work is carried out by the National Ceiling and Visibility product development team under funding from the FAA's Aviation Weather Research Program.
