Performance-based Analysis of Aerodrome Weather Forecasts

Weather forecasting is a critical aspect for optimizing aerodrome operations. It allows ensuring on-ground and en-route safe and efficient air traffic management. Being a continuous and mandatory operation for aerodrome systems, it routinely produces large amounts of data. This paper suggests a customized performance-based analysis of weather forecasts accuracy in line with ICAO (International Civil Aviation Organization) standards. The analysis is instantiated into operational settings of a Euro-pean Weather Service Provider (WSP), and its implications for operations of an Air Navigation Service Provider (ANSP), by means of exemplary data intelligence reports including accuracy indicators. The analysis is meant to support decision makers in managing aerodrome weather forecasting gaining knowledge from past operations.
