Short summary
In May 2017, E-AMDAR service temporarily increased the number of aircraft data over France, especially from from planes ascending from or descending towards French airports. This was the opportunity to check the impact of these additional data on forecast skill scores in AROME-France model. An OSE was carried out by removing about 14 % of E-AMDAR data but a critical step before the OSE was to identify which data could be considered as supplementary. Results of the one-month OSE are discussed.
