Detection, nowcasting and forecasting for airports

MicroStep-MIS, in cooperation with SESAR (Single European Sky ATM Research Joint Undertaking) on the PJ04 TAM project, has developed the Advanced Aviation Weather Decision Support System (AAWDSS).

The AAWDSS is used for detection, nowcasting and forecasting of phenomena affecting airport operation. It includes detection and nowcasting algorithms and forecasting models, such as thunderstorms, low-level windshear and microburst, gust fronts, turbulence, fog and NWP models.

The solution integrates all available meteorological observations and forecasts with progressively finer steps and evaluates them against airport-specific configurable thresholds.

Enhanced common situational awareness is enriched by alerting functionalities based on intensity, duration, probability and related impact assessment. AAWDSS is an advisory tool that provides local procedures related to the alert, to minimize human-factor failure. It informs the user about the current state of significant meteorological phenomena, and provides forecasts (nowcasting) as well as a short history of them to see the trend. Current data, as well as the history of the phenomena, are gathered from a standard AWOS (automated weather observation system) and METAR/SPECI messages. Input data used for nowcast generation are configured to the customer’s specifications.

A regional weather prediction model can be deployed as standalone or integrated with AAWDSS. Furthermore, other models, such as fog prediction or radar-based thunderstorm nowcasting, can be deployed together with radar or integrated with AAWDSS.

The Advanced Aviation Weather Decision Support System can integrate data from multiple sources. It comes with an integrated monitoring system IMS4 that integrates and collects the data from the other IMS4 products. IMS4 is an application software, now its fourth generation since 1993. It is designed for 24/7 unattended operation, all in compliance with ICAO, WMO, ISO, EUROCAE, NATO and EU regulations.
