Aviation safety can be jeopardized by multiple hazards arising from natural phenomena, e.g., severe weather, Aerosols/gases from natural hazard, space weather, and, though not directly affecting the safety of aviation but the planet, the climatic impact of aviation. All in all, the overall objective of ALARM project is to develop a prototype global multi-hazard monitoring and Early Warning System for all these above exposed hazards. Continuous global Earth observations from satellite, ground-based systems, and atmospheric forecasts will be used to feed models capable of observing and predicting (nowcasting/forecasting) the displacement of particles in suspension and gas derived from natural hazards (volcanic ash and SO2, dust clouds from sandstorms, and smoke from forest fire); evere weather situations such as deep convection and extreme weather; exposure to increased levels of solar radiation during flight; and environmental hotspots potentially contributing to global warming in a large extent. Specifically, the aim is to enhance situational awareness of all stakeholders in case of multiple hazard crisis by facilitating the transfer of required relevant information to end-users, presenting such information in a user-friendly manner to ATM stakeholders. In summary, anticipating severe hazards and fostering better decision-making.
