The 14th of June Sandy Chkeir presented the results of the collaboration between SINOPTICA and ALARM projects in the “1st workshop on data science for GNSS remote sensing”, Potsdam, Germany (

The presentation “Leveraging GNSS tropospheric delays to nowcast severe weather events by assimilation into WRF and by machine learning techniques: the hailstorm of 13 July 2021 on Milano Malpensa airport” focused on a specific case study when a strong hailstorm hit the Emirates EK205 aircraft, damaging the fuselage and forcing the pilot to land in Milano Malpensa just a hour after the take off from the same airport.

Sandy presented the nowcasting of the thundertorm performed with the WRF model developed within SINOPTICA and a machine learning algorithm model within ALARM.
