AWIPS era real time TAF, FWC, and LAMP ceiling and visibility verification program at WFO Tulsa

An overview of the Terminal Aerodrome Forecast (TAF) verification program that was developed at the National Weather Service Weather Forecast Office in Tulsa will be presented. TAF prevailing forecast data and the associated FWC and LAMP ceiling and visibility forecasts are gathered for each routinely issued TAF by software on AWIPS (Advanced Weather Interactive Processing System). The verification is done using the FWC/LAMP ceiling and visibility categories. The data are updated every six hours and are available to be viewed by forecasters. Numerous statistical verification are available, including frequency distribution, bias, absolute errors, probability of detection, false alarm rate and critical success index. The data can be sorted by cycle time or six-hour forecast periods, and can be viewed in tabular or graphical form. The graphical user interface, which allows users to easily follow FWC and LAMP trends and gives forecasters immediate feedback on their TAFs, will be presented.
