Automatic TAFs for Aviation
Functionality of the Auto-TAF system |
Auto-TAF is a special MSwr-MOS based system, designed in accordance to the
requirements of aviation, especially of Terminal Aerodrome Forecasts
(TAFs). It consists of three parts:
1) TAF Guidance
It is produced each hour and contains detailed probabilistic MOS
forecasts for all significant weather phenomena regarding wind,
visibility, clouds and significant weather. Very special predictands
like 'Probability for total cloud cover below 1.500 feet is 5 Octa or
more (e.g. Ceiling below 1.500 feet)' are predicted to serve as a
basis for the later generation of short and long TAFs.
Furthermore the detailed information provides a lot of useful
information for the airport authorities to optimize the traffic
flow. It also allows for better decision making for the airlines
regarding the necessary amount of Cerosene at launch.
2) Encoded Auto-TAF
A TAF code generator translates the information of the TAF Guidance
into a TAF complying with ICAO regulations. It looks similar to the
human-made TAF and contains TEMPO and PROB groups as well. Official
verification at Deutscher Wetterdienst over the last 10 years shows
that Auto-TAFs continuously have about the same quality level as
human-made TAFs on the average.
3) Auto-GAFOR
General Aviation Forecasts (GAFORs) covering about 70 Areas in Germany
are generated in the requested format based on the TAF guidances.
