Aviation Weather Decision Support System IMS4 AWDSS System Overview Local AWOS/ARWIS Data The local AWOS and ARWIS system are the source of the accurate real time meteorological data: temperature/dew point, wind, pressure, visibility/cloudbase, runway temperature and runway state. Additional sensors like soil thermometers and soil moisture probes as well as cameras may provide the auxiliary information to the models and algorithms. Data from WMO/ICAO Exchange Networks Having the interface to the AFTN/AMHS/GTS Exchange networks the AWDSS receives and processes the METAR/ SPECI observation...

Aviation Weather Decision Support System System description Gust Front Detection Algorithm This algorithm allows to detect gust fronts form Doppler weather radar data or LIDAR data. Inputs: • Reflectivity • Doppler velocity • Polarimetric data are not necessary, but if available, they increase the quality of results Output is image with gust front position and wind speed values accompanying the front, that is overlaid with airport map. Depending on the system configuration, the IMS4 AWDSS runs on the several Linux duplicated servers dedicated to data acquisition and communication, servers...
